ESC is used to select the Map Mode. It is followed by the illustration of the flight track (North is located at the top!). Additionally stored waypoints are plotted with a cross and name, and the scale is indicated in the lower left part.

F2: Zoom in: The map scale is gradually increased, up to approx. 0.5–1.0 km. Thus single circles are clearly recognisable (dependent on the Recording Interval settings) F1: Zoom out: The map scale is gradually decreased until the display screen is optimised.

OK: Return from any display back to optimised display screen. ESC: Return to flight selection Menu

All other keys cause the track in the current selection to be redrawn. Arrow keys:

During the flight one can blank out by use of the right arrow key all waypoints not being part of the Route. When having left the map screen and subsequently switches back, however all waypoints shall be displayed again. During the flight the current position is shown in the centre. The screen moves by half when the current position is getting to the frame, or when one returns to map mode from any other screen display.

When viewing a flight stored in the flight memory, the displayed frame can be shifted to the top, to the bottom, or to the right or left. This function is not enabled during flight.

Note: Each screen layout may take several seconds, depending on the amount of data. The more track points are already stored in memory, the more time for screen layout is required. If during screen layout a zoom- or pan key is actuated, then the momentary screen layout will be cut short and start over again with the new values. Thus the desired graph will be reached speedily. The track is redrawn back from the current position. This may become important during long-lasting flights with short recording intervals for screen layout.

If altitude is known, this value should be entered directly. (Highest accuracy). If altitude is set using the GPS the reception needs to be of proper quality. In case satellite reception quality is insufficient, difference values in altitude of up to 100 m may occur.

1.4.3 For what do I have to pay attention during the flight?

For nothing! Just enjoy the flight and watch not to commit an air space violation. The instrument shows all important data on the large display screen at any time. The Routes function, the last thermal display and the Wind direction shall assist you in making the right decision. Flight recording is triggered automatically, as soon as the difference in height exceeds 30m within 60s, or if speed over ground exceeds 10 km/h for 60 s.

The most important commands during flight are: ESC key for shifting to map or final approach display screen. If need be, Next Prev WP, in case one is flying a Route and does not want to follow the initial order. Switch-on or switch-off the sink alarm. 14 Mark an excellent thermal with the WP function „Add WP“ 22 Completion of the flight is detected automatically after landing, or it can be cancelled by use of the ESC key. Do not forget switch-off after calculation of the signature.

1.4.4 Data analysis after the flight

Switch-on the instrument and connect to the PC with the Mini USB cable. Caution: at first the USB driver needs to be installed. This is effected automatically when installing Flychart, otherwise you need to install the driver which is compatible to your system software from the CD. Select the correct interface on the flight analysis program (possible programs see chapter data transfer) or have it done by search and then download the flight from the instrument. Several programs provide direct entry to the OLC or similar online competitions. Flychart

Download the flights regularly from the instrument to the PC and format the flight memory with Del. All Records in Menu „Manage Memory“. This way you are ensured to record successfully your flights at any time.

1.6 Entering Text

It is possible to enter text for certain fields, as for example pilot’s name, type of aircraft, aircraft ID, or in regard to Waypoints or Routes the required text on the instrument. However, this procedure is quite laborious. It is indeed much more easier to implement the text entry on the PC by use of the program Flychart 4.52 and to transfer subsequently the data to the instrument. Text entry on the instrument is demonstrated here for the example of a Waypoint: by use of the keys ▲ and ▼ one can select a single Waypoint and alter it after pressing

2 Display Screens

2.1 Altimeter and air pressure

A barometric altimeter calculates altitude from the present air pressure of the atmosphere. Air pressure will decrease at increasing height. Due to the fact that air may be compressed, the pressure decrease is not linear, but indeed exponential. The basis for altitude calculation in aviation is an international formula which defines a standard atmosphere. In the CINA- Standard atmosphere the basic pressure on sea level is 1013,25 hPa (Hektopascal) at a temperature of 15°C. Furthermore it defines a continuous temperature decrease at increasing height of 0,65°C per 100m ascent. Therefore is binding: a barometric aviation altimeter displays the precise altitude only if weather conditions are in exact accordance to the standard atmosphere. In practice, such analogy is more likely to be the exception! Air weight and pressure are strongly influenced by air temperature. If temperature deviates from standard atmosphere, the display of altitude calculated as per the international formula is no longer correct. The altimeter displays during summer, when temperatures are higher, indeed altitude parameters which are too low, and during the winter it is exactly the contrary! Flying at lower temperatures is effectively done at lower altitude, and at higher temperatures flight altitude is higher than the altimeter displays! The deviation of 1 °C per 1000 height meters induces approx. 4 m error. (This empirical formula is valid for up to 4000m!) If you fly during summer through 2000 height meters in an air mass being too warm by 16 °C compared to standard atmosphere, the altimeter will then display 2 x 4 x 16 = 128m difference in altitude under real height! Based upon the internationally determined altitude calculation with standard values, this display error caused by air temperature shall not be rectified by the instrument. Air pressure changes in relation to weather conditions. In order to compensate for display fluctuations, an altimeter always needs to be gauged. This means that the altimeter has to be set precisely before take-off for any flight to a well-known altitude value. Caution: the atmospheric pressure may change during the timeline of one day up to five Hektopascal (for ex. cold front). As a result this is after all the equivalent of more than 40 meters height difference. There is another possibility to gauge the altimeter which is to enter the current QNH pressure value. The QNH (Question Normal Height) applied in aviation matches the current local air pressure, as it would be at sea level, so that the altimeter would indeed display 0m. Due to this process the local pressure data recorded by the various measurement stations is area-wide comparable, irrespective of the geographical height. The QNH-value is subject to be continuously updated and may be read in the flight weather report, or required by radio from airfields, or by enquiry on the Internet.

The instrument provides 3 altitude displays.

2.1.1 Altimeter A1, absolute Altitude A1 is always the altitude above sea level (large display in upper part of display screen).

Altitude A1 is originally set by the manufacturer to show the correct altitude of user’s location if air pressure at sea level is 1013 hPa. Bearing in mind that this only happens infrequently, the displayed altitude A1 should be gauged before each take-off to the actual, true height at location. Correction of altitude A1: Long pressure on

⇒ will generate the message Mod Alt1 ↑↓ in the lower information line.

- 12 -

Operating Manual Flytec 6020

Pressing the ▲key will increase the displayed altitude, the ▼ key will decrease altitude. Due to this adjustment the air pressure display will also change. This air pressure value (QNH) is always related to the height at sea level.

If the user does not know the altitude of his present location, he may obtain the data by fading in the „User Field QNH“ and, using the arrow keys, by changing the altitude value until the QNH matches the actual QNH as per weather forecast.

If the GPS system receives satellites, the GPS-altitude is applied as Alt1 by pressing the

(Alti GPS) key. If there is no GPS reception, it is possible to set the altitude Alt1 by use of the function key of 1013 hPa. If the altitude A1 of any given landing place is set to 0m, then after take-off there will of course always be displayed the altitude above this location. The related air pressure (QFE) is the real present air pressure at this place in hPa, which differs of course from QNH, which is the pressure at sea level, according to the difference of altitude.

Within the user selectable fields it is also possible to choose altitude A1 in ft. This information is important when being in contact with the air traffic manager in Restricted Areas.

Furthermore it is possible to choose FL (ft) in the user selectable fields. This value is an altitude display in feet for the Flight level (FL). This feature is not adjustable and is always related to a QNH value of 1013 hPa (air pressure at sea level). This display is particularly important for pilots of microlight aircraft to whom is assigned a Flight Level by air trafficcontrollers during flights in Restricted Areas.

2.1.2 Altimeter A2, relative altitude A2 (within the user selectable fields) is a reference altitude, it can be modified by use of the

arrow keys ▲▼. Correction of altitude A2: Long pressure on

By use of the arrow ▲▼ keys it is possible to set the height difference, or to set with brief pressure on

(SET 0) the height difference to 0.

2.1.3 Altimeter A3, cumulated altitude A3 (within the user selectable fields) sums up the total height meters gained during one

flight. For thermal flights this height is dependant on flight time. If several pilots complete the same flight task, then the one who had the least gain in height (A3) would have been the best to accomplish the task.

A2, A3, FL or QNH can be selected within the user selectable fields. (see page 10).

2.2 Variometer functions

2.2.1 Analog Vario

The most important indication for a non-motor driven aircraft is without any doubt the Variometer. It displays the vertical speed in meter/second and informs the pilot about the actual climb or sink rate.

It is only possible for the pilot by using the Vario (and its accompanying acoustics) to determine the most efficient thermal climb, and in the opposite situation, to recognise when he is sinking too rapidly in downwind and should leave them at best speed.

The scale of the analogue display is 0,2 m/s. The range of the first scale extends from 0 up to +/- 4 m/s, thereafter the scale display switches automatically and the range of the second scale extends from 4… 8 m/s. . The response characteristics of the analogue Vario and of climb

acoustics can be set within a wide range. In order to simplify the settings, Flytec has determined 5 basic filters which can be set by the Flychart program to particular requirements when using a special command.

2.2.2 Digital-Vario Average- or Netto-Vario The Digital Vario has a scale of 10 cm/s and an extensive measuring range of

up to +/- 100 m/s. It is therefore also appropriate to display the vertical speed for parachutists during the jump. It may be provided with a time constant from 1 … 30 s in the Set-Mode under "Variomode" as average value-Vario (also called integrating Vario). This feature is useful to provide a more settled Vario display inside a rough thermal. Integration time should be selected more longer in accordance to the thermal’s roughness.

2.2.3 Acoustics and Volume Level (Sound)

The Menu Climb acoustics facilitates the versatile setting possibilities of the Flytec 6020 GPS Vario – Acoustics. This feature enables a rapid and easy adaptation to the pilot’s requirements. By short pressure on the The adjustable sound levels are: 0 - 25% - 50% - 75% - 100% - 0. The selected value is displayed on the information line and confirmed with a short beep or double-beep.

Automatic volume control: with the basic setting levels 25 50 and 75 % the volume level will be slowly increased automatically, once the airspeed exceeds 40 km/h. However, it is impossible for the volume level to exceed 100%.

damp

Dampening The Variometer value is recalculated every 0.2s. In case of

rapid Vario changes and setting of quickly increasing tone pitch, this may possibly result between two calculation phases in a quite important modification of tone frequency. The ear perceives this incidence as a kind of fast “piano effect”. In order to diminish this effect, a damping feature may be fitted. Then rapid tone pitches are honed in the frequency. As a result, the Vario sound has a smoother

response.

2.3 Speed

The 6020-GPS provides a speed measuring inlet for a wind wheel sensor. This item displays the true flight speed through the air and starts correct measuring above 1 km/h, it is therefore also very convenient for determination of the wind strength at take-off. The speed measuring inlet can be adjusted by implementing a correction factor. Factory setting is always 100%. Main Setup Menu This correction is helpful, if the speed sensor can not be fitted at optimum.

The wind vane sensor measures the True Air Speed (=TAS). Speed is displayed in digital mode.

2.3.1 Speed without Speed Sensor

Frequently hangglider pilots fly without any speed sensor. In this case it is possible to present the GND-Speed as digital display within a freely selectable user field. The 6020-GPS calculates from GND-Speed, as well as wind direction and strength a computed air speed. However, this indication of air speed without speed sensor is just an approximation to the effective air speed. This is in many cases sufficient to do certain assessments, e.g. if the goal can be reached or not. The data of wind direction and strength are established in this case by flying one or more circles. The instrument computes wind direction and strength from the disparity. It is recommended to pilot’s flying without speed sensor to fly from time to time an entire full circle in order to establish wind direction and strength. Due to the fact that the calculated air speed is related to the wind data present at the location where circling was effected, the calculated air speed is no longer valid under different conditions of wind data. The air speed calculated without speed sensor is the True Air Speed. See Chapter 2.7.3 Wind direction and strength page 31.

2.3.2 Stallalarm

This audible alarm is consisting of a deep tone with short beeps and always with 100% volume level. In Main Setup Menu set the speed for activating the stall alarm, and likewise, the altitude can be set to the point from where up the alarm is active. If the stall alarm is set to the value of 0 km/h, the alarm is turned off. Stallalarm is only enabled when wind vane wheel is inserted. Furthermore, it is only enabled between 15 km/h True Air Speed and the selected Stall speed.

These settings are effected in Main Setup Menu Notice: all internal calculations of the instrument are made in UTC (Coordinated Universal Time). The local time is just used as „Time“ display and calculates simply the UTC plus or minus the UTC Offset. The local time is also binding for the take-off time at Competition Routes.

2.5 Temperature

The instrument Flytec 6020-GPS needs a temperature sensor for the temperature compensation of sensors, as well as for the automatic display contrast control. Temperature reading is possible in degree Centigrade or Fahrenheit. Main Setup Menu Caution: the sensor measures the circuit board temperature. The inside temperature of the casing may be higher or lower than the ambient air temperature, especially when the instrument is exposed to direct sunlight.

Instr. Settings ⇒ Units.

2.6 Navigation

Navigation activities without operating GPS-Receivers is unthinkable these days. Indeed a chain of satellites is orbiting the Globe. It provides the possibility to determine worldwide one’s own position very precisely, if min. 4 satellites are received simultaneously. The Flytec 6020-GPS computes various indicators via the positioning feature by GPS.

2.6.1 Assessment of reception quality

The 6020-GPS is fitted with a 16-channel GPS-Receiver which is featured with lesser power consumption and also a significantly shorter satellite detection time. Accuracy of position is between 7 to 40m. As an average one may assume approx. 20 m.

Normally the instrument recognises its position under unobstructed view conditons after maximum 1 to 2 minutes. If the receiver is switched-off for a short time (less than 2 hrs.), the time for new position finding is less than 10 seconds as a rule. Buildings, mountains or thick forest affect reception quality of the receiver. Therefore, one should always look for the best possible visibility around and the antenna in the casing should be pointed upwards if applicable. In particular when mounted on the steering holder of the hangglider, we recommend not to have the instrument fixed under the pilot’s head on the middle of the basis, but indeed sideways. In this position the 6020-GPS should not have more than 45° deviation from horizontal position so that the antenna points upwards.

- 18 -

Operating Manual Flytec 6020

Because the receiving intensity of the satellite signals is only approx. 1/1000 of mobile radios, any radio equipment and other disruptive factors (like notebooks) should be operated as far away as possible from the 6020-GPS. The number of received satellites is shown on the upper right side of the bar scale. The longer the bar, the more precise is the reception quality.

As soon as the instrument has sufficient GPS reception after energising, the date and time of day is recorded into the internal memory. This action is signalled by the instrument with a slight beep tone.

2.6.2 Compass and Flight Direction

In contrast to a normal magnetic compass which is oriented to the magnetic force lines of the Globe, the GPS compass can show the direction only when the user moves about. However, it has the advantage that it is not subject to any grid deviation and does not show any deviation as a result of iron or any magnetic material either. Its zero point always corresponds with the true geographic north (=0 or 360 degrees). The course, that is the flight direction (= Track), is calculated from a series of positions. If the user remains stationary at the same location, then the course and compass needles are undefined. The exact course (this is the direction in which the user travels over ground), is always at the top of the compass, but can also be read in the display “Track”. When circling in a thermal the compass rose only appears to turn; in reality the needle does not move; it’s the casing along with the aircraft, which moves around the rose.

2.6.3 Track und Bearing

The Track is defined as the direction of movements of the aircraft over ground. The geographic true North is always 0 or 360 degrees (East = 90, South = 180, West = 270 degrees). As the bearing is designated the direction (according to the system described above) to a selected waypoint seen from the viewer.

2.6.4 Waypoints and coordinates

A waypoint is any single point on the earth’s surface that you would like to go to. The 6020-GPS can save up to 200 different waypoints. Each waypoint can have up to 16 characters, e.g. to enter the altitude, i.e. positioning of waypoint on the earth’s surface. For this purpose the 6020-GPS utilises the geographical map system named WGS84 (World Geodetic System 1984). This reference system assumes that latitude is measured from the equator to the North Pole with 90° N, and to the South Pole with 90° S. Longitude is measured from the Greenwich zero meridian (near London), East is counted positive and West is negative, up to +/- 180°.

The 6020-GPS also understands waypoints entered according to the previous norm, introduced by Bräuniger: 3 letters and 3 numbers. Example: FIE112 indicates a waypoint with the name FIExxx and an altitude of 1120 meters above sea level.

In Basic Settings / Coordinate Format the data entry format is selectable between:

1) Degrees Minutes Decimal places of Minutes (dd°mm.mmm) (Factory setting)

2) Degrees Minutes Seconds (dd°mm’ss“)

3) Degrees Decimal places of degrees (dd.ddddd)

4) UTM (a grid system with 1 km raster in both NS and also in EW direction)

5) Swiss Grid

Basically one should always select the first possibility (=factory setting), because only this format is using exactly the same calculation format as the GPS receivers do. With all the other formats rounding errors could sum up to 20 m.

Computing is only done with the WGS84 system. Differing geodetic systems can no longer be selected.

2.6.4.4 Distance to Waypoint

Only in case a waypoint has been selected manually with the "Goto" function, or automatically with the "Route" function, the horizontal distance seen from the viewer to the waypoint is displayed. The scale is 10 m ( for distance under 10 km ) otherwise 0,1 km.

2.6.6 The Competition-Route

In contrast to the routes described above, the Competition-Route contains waypoints which are mandatory to be reached; for example turning points in competition or FAI-record flights, or performance flights. The regulation, which only recently came into effect in documenting distances flown, fully relies on the recording of GPS-Receiver position data (Tracklog points).

It is only when flying Competition Routes that the pilot will be warned by an acoustic alarm when approaching his waypoints or when leaving the start cylinder and that the unit switches automatically to the next waypoint. Call-up of the Competition Route is

effected by prolonged pressing of the

key and confirmation by OK key. The CompetitionRoute, once it has been activated, remains enabled even after switching-off the instrument. It can only be disabled by prolonged pressing of the

key followed by F2 Cancel Route.

Instead of the previous photographic sectors the pilot only needs to reach a predetermined distance to the turning point. It is also called the entering flight into the cylinder.

circumference of 400 m is pre-set.

Setting of the differing cylinder radii, of start time, the flight task (=Entering or Exiting the start cylinder) is effected upon data entry of the Competition-Route.

Beside the automatic shift to the next WP, the pilot can also shift manually by use of arrow keys ▲ or ▼ to the next or to the previous WP.

2.6.6.1 Flying Competition-Routes

Because the GPS-Receiver of the 6020-GPS identifies its new position every second, it takes only this one second to inform the pilot about his crossing of the turning point cylinder circumference or that the time has come to leave the start cylinder. In this case a long, unmistakable tone sounds during 2 seconds (CMP-Sound) and the instrument switches automatically to the next waypoint of the Route. Independent of what recording interval for storage is used during a standard flight, it is anyway guaranteed that several Tracklog points are saved in the memory of the 6020-GPS at one second intervals when crossing the cylinder circumference.

Usually the start cylinder is in first position of the Competition-Route. (However this is not mandatory). If during setting or changing the Competition-Route after marking a waypoint the key

McC

is pressed, the letter “S” for Start-Cylinder appears behind the WAYPOINT name. The “S” disappears if the same key is pressed again. Only if a waypoint is marked with “S”, it is necessary to set also a Start time and as task ENTER or EXIT. If no WAYPOINT has been designated as Start-Cylinder, the pilots are not bound to observe a start time and the automatic shifting to the next WAYPOINT is effected, as soon as the pilot is present inside the cylinder.

If however in a competition a start cylinder is predetermined, the valuation starts as soon as the start time is reached under these conditions:

Startmode EXIT: if the pilot leaves the cylinder from inside to outside. Startmode ENTER: if the pilot crosses the Start cylinder from outside to inside.

It is possible to choose several start gates.

During a flight the pilot can see on the Info-field display via count-down how many seconds / minutes are left before opening of the Start line. At the same time he can read in the display „Dist to WP“ and “Dist.Cyl” if he is inside or outside of the start cylinder. If the pilot has flown out of the WP-Cylinder and the instrument has shifted to the next waypoint, it is possible by pressing the ▼ arrow key to switch back at discretion to the previous waypoint, and by pressing the ▲ arrow key to shift again to the next waypoint. This is useful when a pilot, after having left the start cylinder, has decided to fly back and to restart at a later time.

Also during the flight in Competition-Route, it is possible by using the Goto-key (prolonged pressing) to call-up additional waypoints (thermal sources), sorted according to their distance from the pilot. The waypoints being part of the Competition-Route are marked with an asterisk in the displayed list; this means it is mandatory that they need to be approached. Even in case a waypoint not belonging to the Route has been called-up, the alarm remains enabled when entering the cylinder of the waypoint belonging to the Route. With the it is possible to toggle back and forth between the waypoint of the Competition-Route and the other waypoint.

After completing a flight task, the waypoints belonging to the Competition-Route will be listed in the data transfer to a PC under the header of the IGC file. A n appropriate PC program can check therefore if the assigned task was completed correctly.

When setting up a Competition-Route without a start cylinder, i.e. without a start time, the automatic switch over to the next waypoint is effected, as soon as the pilot is present inside the 1. cylinder radius. So it makes no sense to choose the “Take off” place as the 1 waypoint, because immediately after receiving satellites the instrument switches over to the next waypoint.

2.6.6.2 Competition-Route Set – Alter – Delete

Even so a called-up Competition Route is treated differently than a usual Route during flight and also for data transfer after the flight’s completion, there is no difference when setting or changing it. The route can be set up with the help of the keypad of the instrument or can be transferred from the PC. This feature is particularly useful for Competitions when in a short time the flight tasks on the basis of turning points have to be distributed error free to many pilots. The waypoints of the Competition-Route can be altered, however the designation „COMPETITION Route“ can not be deleted. If the CompetitionRoute does not contain any waypoints, it cannot be selected.

2.6.6.4 Dist to Goal (Total distance to the Goal of a Route)

In this field there is displayed during flight of a Route the sum of the legs lying in front of the pilot. The distance is calculated from the current position. Thus he knows at any moment, how much km are still in front of him until completion of the task

2.6.6.5 Distance to starting point

The instrument memorises the coordinates of the point, where the start recognition (flight acceptance) has begun. This is a GND Speed of 10km/h for more than 60 seconds. With user field “Dist.Start” the distance to this point can be illustrated. Usually this is the point from where one has started.

2.6.7 Diff. BGGoal

Furthermore it is possible to pre-calculate the expected arrival altitude above goal over several waypoints for display in the user defined field „Diff.BGGoal“. This computing incorporates wind strength and direction, which one has determined by flying a full circle.

Hereby it is assumed that one is flying from the actual position in direct flight to the next waypoint, and continues from there on the Route. The calculation is assuming that one is covering the leg with the speed of best glide. On this note it is simply an estimation, allowing the pilot to determine his strategy under consideration of local topography and of wind components. The display shows the pilot if he has sufficient height to fly over the last waypoint directly to the goal. See also chapter 2.7.4 (= L/D ratio) page

2.6.8 Relocating Thermals

With weak or widely dispersed thermals this function helps to relocate any lost thermals. A small arrow pointing up in the compass rose shows the direction to the last thermal with at least a 1 m/s climb. If this arrow is positioned at the top of the display, then you are flying towards the thermal, however, if it is positioned in the lower part of the display, you are flying away from the thermal. In case one wants to use this function, then the indicator "Dist Therm" should additionally be activated in the user defined fields. This value indicates the distance from the pilot to the last Thermal.

This field indicates the shortest distance (perpendicular to the Track and related to a map view) to the active leg of a Route.

The accuracy of the indicated value depends on the length of the active leg. The largest Inaccuracy arises in the centre between start and the next waypoint, if one is very close to the track (the angles become very flat). With 50 km distance between start and waypoint, the inaccuracy in the centre can reach up to 400m. Positive values are displayed if one is on the right of the track, negative values on the left of the track. Even if one has cross flown over the next waypoint, the distance to the straight line is shown. (see position 3).

2.6.10 Air Space - CTR (Restricted areas)

On the 6020-GPS up to 150 CTR’s can be entered. The CTR’s may comprise straight lines and arc segments, or also be circles. These sectors appear in the Map Mode. Each CTR may be composed of max. 110 waypoints.

Information to number of endpoints / elements

The CTR is defined by endpoints and arc segments or just by a circle. When entering these elements it must be taken care of that the endpoints are precisely created in their order of appearance (to the right or to the left) in which these lines should be displayed later. The 6020-GPS instrument draws automatically a line from the recent waypoint to the first one. It is therefore not required to repeat as last waypoint the first one.

2.7 Flight optimisation

2.7.1 Groundspeed (Speed over ground)

The GPS-Receiver calculates its new position once every second. Speed over Ground is derived from the distance between these positions. From the difference between Airspeed and Speed over Ground it is possible to reach conclusions about the wind’s influence.

2.7.2 Head- Cross or Tailwind; the Wind component

During a flight to goal or in calculating a final glide, it is not really the absolute value of wind, but the wind component, i.e. the difference between Ground speed and Air speed, that is decisive. In most cases the wind does not blow directly from the front or from behind, but somewhat from the side. If this wind component “Spd-Diff” (in the user defined fields) is positive, then the pilot will fly with a tail wind and the glide ratio over the ground will improve. If it is negative, it contains at least a part of head wind and the glide ratio over ground will decrease. The 6020-GPS takes this wind portion in any case into consideration for calculation of the final glide. The Windspeed can be displayed as user field.

If the windsock indicating the wind direction covers the wind symbols N E S W, then for reasons of clarity the corresponding letter positioned below shall disappear!

2.7.3 Wind direction and Wind speed

It is very important to know the wind in direction and strength, especially in case of an out landing. The Wind strength can be selected In the user defined fields. However, for this purpose it is necessary to fly one or two complete circles as steadily as possible. Whilst circling, the 6020-GPS determines the direction of least speed over ground and checks also synchronously if in opposite direction there might be the fastest speed over ground. .

Therefrom it is possible to compute the values for wind direction and wind speed. Wind direction is shown in the compass rose at the position from where the wind is blowing by a small windsock symbol. During the landing approach this symbol should always be at the top.

Operating Manual Flytec 6020

2.7.4 Glide ratio ( = L/D ratio) By definition, the glide ratio is calculated by taking the horizontal distance traveled and

dividing it by the height which was lost. If instead of the horizontal speed is taken the speed through the air, the error is 2% at glide ratio 5 and just only 0,5% at glide ratio 10. This small inaccuracy is insignificant and may be disregarded

Within the user defined display fields the glide ratio may also be selected. Hereby the following facts are applicable: Glide ratio through the air:

L/DAir

= TAS/Sink True Air Speed divided by Sink rate Glide ratio over Ground : L/D Ground

= GS/Sink Speed over Ground divided by Sink rate Required Glide ratio over Ground from momentary position for reaching selected WP: L/D Req = Distance to the WP / Height difference to WP Required Glide ratio over Ground from momentary position for reaching the goal.

example for explanation of glide ratio (L/D) values:

Best glide – exit point 931m over the goal

act. height

956m

681m

Alt a BG 275m

Best glide 8

L/D req 5.7

2km

Act. distance to WP 5.45 km

This field indicates the required glide ratio over ground to the goal crossing several waypoints. This user field is only displayed if a Route is active. This way it can be decided, whether one should be flying directly to goal while crossing several waypoints, or whether one must gain height in between within a Thermal. The calculation does not take into account if there is a waypoint in between with higher altitude than the direct line from current altitude position to the goal.

2.7.5 Safety altitude over the path of best Glide – Diff.BGWayp and Diff.BGGoal

In order to evaluate if one has sufficient safety altitude, these two user fields display the difference between current altitude and the altitude which is necessary to reach the goal with the speed of best glide. The best glide includes the momentary flight conditions. Up-wash and down-wash, as well as head- or tail wind are also taken into account. However, this calculation does not consider that on the path to the active waypoint other climb- or sink zones can be incorporated, or that the wind values accounted for in the computing can be

- 32 -

Operating Manual Flytec 6020

subject to modification. Furthermore the glide ratio for best glide as entered into the instrument settings must be correct. If the Diff.BGWayp is positive, it represents a safety altitude which the pilot may loose accessorily for reaching the active WP even so while flying with the speed of best glide. If this altitude is negative, the pilot needs to circle up to at least the indicated altitude for reaching the goal.

Diff.BGGoal calculates this altitude over several waypoints of a Route to the goal, starting from the current position.

2.7.6 Display screen final approach

In order to realise all these data at a glance, the Flytec 6020-GPS provides a specific display screen which shows the pilot in an intuitive mode, if he can reach his goal and in which way he can reach it optimally. After repeated pressing of the approach appears as in the illustration on the right, for graphic presentation of the calculation for final approach. Cross hairs show the path to goal, a glider symbol in relation to it, and the pilot’s position. The horizontal scale of the cross hairs shows the deviation between current track and goal (e.g. caused by shearing winds). Each graduation line corresponds to 10°. In the illustration the pilot is drifting by 22° too far to the right. The vertical scale shows the glide ratio. In the intersection of cross hairs is positioned the best glide ratio of the wing as entered into the Basic Settings. When wind is encountered, this glide ratio shall be rectified by the corresponding wind component. Each graduation line corresponds to 0,5 glide ratio.

2km

For the example given above the pilot has entered the best glide ratio 8. If he would be precisely on the path of best glide, the wing symbol would be exactly on the horizontal line, and „Alt a.BG“ should be 0. Because his distance to goal is still 5,45 km, his altitude should be in this case by 5450 : 8 = 681 meters higher than goal. However, „Alt a.BG“ indicates 275 m, therefore he is by 681 + 275 m higher than goal. The required L/D is indeed 5450 : 956 = 5.7. The paraglider symbol is therefore 8-5.7= 2.3 Units or 4.6 crosshairs above the best glide line .

The strategy during the final approach is to hold the symbol in the cross-point. In order to have some margin, experienced pilots will rather hold the symbol somewhat above the cross-point of best glide.

During thermalling, the symbol remains on the vertical axis. As long as the deviation is more than approx. 20 L/D, the symbol appears in grey in the centre. Below of approx. L/D 20 the symbol disappears. Upon approx. L/D 6 it reappears again on the screen bottom-up. When it goes upside over the upper margin, it will again appear in grey.

Also during thermalling there is a small arrow ^ as exit assistance in the upper part, if Track and Bearing correspond to each other within +/- 10°. When sinking the arrows <^> show a recommendation in which direction one should head for. If the symbol leaves the range of approx. plus minus 60°, it shall be presented in grey. In this case one should shift back to the Vario screen using the the compass rose with its direction pointers.

2.8 Battery - Management

Two Bargraph scales show the charge state of the batteries. The Flytec 6020 is provided with 2 battery banks with 2 batteries each. Bank 1 must always be loaded. Bank 2 may be kept unloaded. However, it is highly recommended to also equip Bank 2. As soon as Bank 1 batteries are discharged, the instrument automatically switches to Bank 2. We recommend to place the partly discharged batteries of Bank 2 after a long flight into Bank 1 and to place new batteries into Bank 2. In doing this it is ensured that you may use up the batteries completely without taking the risk that during a flight all the batteries are discharged.

The following batteries are appropriate for use:

• 2 pieces each per Bank Alkaline High Power batteries 1.5V size AA.

Estimated operation time - 2 times 20h = 40h in total

• 2 pieces each per Bank NiMH accumulators 2100mAh or more, 1.2V size AA.

Estimated operation time - 2 times 15h = 30h in total.

The correct battery type needs to be set in Main Setup Menu

If a wrong setting has been entered, it may induce to the result that the instrument prematurely switches off completely, when changing from Bank 1 to Bank 2.

We recommend not to use NiCd accumulators. These batteries have significantly reduced capacity and they are less environment-friendly. Also the switching threshold data are not laid-out for NiCd Accumulators.

The estimated operation time mentioned above is based on normal temperatures (20-25 °C). At low temperature the batteries and accumulators have a considerably shorter service life.

4 Flight Memory and data analysis

The flights are recorded inside a Flash-Memory (see below). Each trackpoint contains time of day, position, GPS-altitude, barometric altitude as well as speed through the air. Due to this feature it is possible later on to reproduce the barograph and individually the graph for Vario, Speed, and the track (course) of the flight over a map presentation. These data are processed for flight analysis by various analysis programs. With Flychart 4.52 it is for example possible to retrace the flight on the PC-monitor in three-dimensional mode over the corresponding territory. (Google Earth).

Operating Manual Flytec 6020

For tests or acrobatic flights a sampling rate of 2 seconds is recommended. However, the recommendation as standard setting is a recording interval between 5 and 10 s. With it also narrow curves are well recognisable, and the number of data points for the external computing of OLC points remains manageable. Factory setting here is 10 seconds. For the beginning of a flight the following arrangement applies:

the start is recognized as soon as the ground speed reaches at least 10 km/h for more than 60 seconds, or if altitude difference within 60s is more than 30m.

In each case however, the previous flight history with up to 30 recording points is filed in the 6020-GPS memory. With it, and at 10 sec. recording interval, even the last 3 minutes before the start of the filed flight can be noted.

An end of flight is recognized under automatic recording if there is no speed for 60 seconds (less than 10 km/h speed or airspeed) and also if no change in altitude occurs.

Then the standard display screen is automatically switched to flight analysis. From this moment on the “digital signature” of this flight is calculated and a notice is displayed in the info field. Please wait until this calculation is completed. With short pressing on the one returns to normal mode.

It is also possible to shift the instrument to manual recording. For this purpose it is necessary to select under Main Setup Menu

⇒

User Settings ⇒Flightmemory ⇒Rec.

Auto/Man the value “No”.

This setting enables the recording to start approx. 10 seconds after switch-on and is only stopped after the

Page/ESC On/Off

key has been pressed for 3 seconds.

The start of recording is visible by the running “Flight time” counter. Please take into account that altitude A1 may not be changed during recording process.

Caution: Make sure before the start that the GPS-Receiver indicates to receive at least 4 Satellites in order to achieve valid recordings.

Comment 1: in the Flight analysis are displayed max. values which appeared during the flight. Due to the fact that the display screen is updated every second, the 1-second values are saved for the flight analysis. If one undertakes a download of such a flight afterwards on the PC using a program such as Flychart, SeeYou, CompeGPS, MaxPunkte etc., these programs are only appropriate to analyse the flight records in IGC format. In the IGC file are saved the time of day (UTC), position, barometric altitude, GPS-altitude and True Air Speed of the wind vane or pitot pressure sensor. The programs calculate the Vario-meter values out of the altitude data. If for instance, one has set a recording interval of 10s, and has made a height difference of 5m during these 10 seconds, the Vario value of 0.5 m/s shall be calculated. However, during this time a 1-second Vario value of 2m/s may have been performed. Only this value shall be indicated on the Flight-Analysis page and is not subject to electronic readout.

Comment 2: Although the instrument is capable to store up to 100 flights, we recommend to save the flights in regular intervals on a PC and to reformat the flight memory afterwards by entering the command Main Setup Menu

4.2 Data transfer

In the memory of the 6020-GPS are saved all data entered by the pilot, such as waypoints, Routes, pilot’s name etc., as well as the automatically by the instrument recorded tracklogpoints of the flights being performed. Each one of these points contains the time of day, position, GPS-altitude, barometric altitude, as well as the flight speed. In this way it is possible to graph the Barogram, Variogram, Speedgram and the track (course) of the flight over a map presentation for later analysis. With Flychart 4.52 it is even possible to retrace the flight on the PC-monitor in three-dimensional mode over the corresponding territory. For this purpose the software program Google Earth needs to be installed.

4.3 Data exchange via PC

The basic equipment of the 6020-GPS includes a data cable for a USB PC interface USB Mini B. Due to this feature data transfer can be carried out in both directions. The data transmission is effected via serial interface COMX with: 57.600 baud; 8 databit; 1 stopbit; no parity, Xon/Xoff.

Using the USB interface the 6020-GPS can also be operated for data readout and entry:

• entire instrument configuration (Basic Settings, User def. fields)

• list of waypoints

• list of Routes

Only readout of flights saved in the flight memory is possible.

Important: for transfer of a.m. data the 6020-GPS must first be switched-on and the relevant

program for data transfer has been called-up, before the connection cable to the PC is plugged to the 6020-GPS. Important: at first the USB driver as provided from Prolific has to be CD installed. Upon installation of Flychart the USB driver installation is effected automatically.

To perform data transfer the instrument needs to be switched to the Main Setup Menu by prolonged pressing on the Please observe the instructions of the software being used for transfer of stored flight data. (For most software programs it is required to shift to the Flightmemory resp. to the FlightAnalysis mode). There are various software programs available for creation of IGC-files, partly even for OLC-files. For more detailed information please check homepage

We recommend the use of Flychart which can be downloaded from the website. With Flychart all instrument settings can be effected comfortably on the PC.

4.3.3 Airspace (CTR)

The same principle applies on Airspace. For this purpose please activate button „Airspace“.

4.4 Transferring new software to the 6020-GPS

As is the case with many other present-day instruments, there is also the possibility to up-date the software version (Firmware). Hereby future requirements presented by pilots or new Competition regulations may be rapidly implemented. The manufacturer Flytec shall post from time to time program up-dates of the 6020-GPS firmware on its Internet homepage, which can be downloaded by the user free of charge for storage and subsequent transfer to the 6020-GPS. In order to be able to write into the 6020-GPS flash memory with a PC, the program “Flasher.exe” is required, which is available in zipped format file under the name of “Flasher.zip”. In addition, also the intrinsic firmware to be uploaded has to be obtained from the homepage. Its name is e.g. “6020v325.moc” (approx. 500 KB) which is equivalent to version 3.25. We recommend to save all the related files in one single subdirectory (e.g. C:\Programs\ FlytecFlasher\).

Operating Manual Flytec 6020

After decompressing the ZIP file a number of files are created. Double clicking on the file “Flasher.exe” starts the program.

One can set the interface, or in case it is not known, having it done by automatic search. With "File" you select the program to be transferred with the extension " .moc " or you can pull it from the Explorer into the field by drag & drop. Boot the data transfer. The bootloader version of the instrument will appear and the transfer rate. The numbers appearing in the field on the right side are the instrument’s response.

Important: By contrast to the flight data transfer make sure that the 6020-GPS is not switched-on when the connection cable to the PC is plugged. Caution: Never leave the PC cable hooked to the instrument for a longer period when it is turned off. Indeed this is energy consuming and the batteries could be discharged unnoticed.

Lead: In Windows the characteristic noise for USB devices should be audible when the unit is plugged.

7.1 Landing in Water

In case you are forced to land in water with your 6020-GPS and it may have penetrated the instrument, there is still a chance to save the instrument or at least some of its parts. Once water has intruded the GPS module it is then irrevocably lost. Take out all batteries as fast as possible, thereby the circuit is disconnected from power supply. Then afterwards the casing can be opened. In presence of aggressive liquids, such as salt water, place the circuit board and all parts affected by the salt water into warmed freshwater for a minimum of about ½ hour. Thereafter dry the instrument carefully with warm air (hair dryer). It is also recommended to remove the flat cable of the keypad. Please return imperatively the dried instrument to Flytec Company for final check over.

Any claim under Warranty is void after a Water landing.

9 Appendix

9.1 Altimeter

An altimeter is really a barograph because it doesn’t directly measure altitude, but air pressure. Altitude is calculated from air pressure data. The pressure at sea level is used as zero point altitude for the calculation of absolute altitude (according to the international altitude formula).

Why does pressure change with altitude? Pressure at any given point on the earth is created by the weight of air in the atmosphere above it. Therefore, pressure reduces with height – there is less air above you. A change in pressure of 1 mbar at 500 metres local altitude above sea level is a height difference of about 8m. However, in practice, it is not as simple as that because more factors have influence on air pressure. Therefore, air pressure is also depending on temperature and of course, on weather conditions. On a stable day, temperature induced air pressure variations of 1mb can occur, which means a height difference of ± 10 metres. Depending on the weather, air pressure at sea level (QNH) may vary from 950 mb to 1050 mb. In order to eliminate the influence of the weather, the altimeter has to be calibrated again at certain intervals. This means the altimeter has to be set to a known height and it needs to display this height.

During rapid weather changes (e.g. passage of a cold front), the air pressure can change by up to 5 mbar during one day. This means a height difference of 40 m!

Another alternative to calibrate an altimeter is setting it to the actual QNH. What is QNH? General air traffic needs a common zero point. This means that at a certain

altitude all aircraft show the same altitude on the altimeter. This common reference basis is the QNH. The QNH is the actual air pressure in hPa ( 1 hPa=1mbar ) calculated back to sea level. It is calculated several times a day and can be taken from the weather forecast for aviation or it may be requested by radio from airfields.

9.2 Speed

9.2.1 True or Indicated Airspeed - TAS or IAS

In general aviation it is customary to measure the airspeed by use of a pitot tube as a dynamic pressure speed (=IAS) and also to display it as such. The advantage of this method is the fact that at any altitude level the maximum admissible speed or the stall is marked (flight safety) at the same position on the scale. Furthermore it is the same for the speed of best glide for any altitude which is on a fixed position on the scale (flight performance). It is however the disadvantage of this system that all geographic calculations, such as for distance, required flight path angle, and all final approach computing, necessitate the true air speed to perform the calculation. Another disadvantage is the fact that the indicated speed is correct only at one certain altitude (usually at sea level). The higher one climbs, the glider will fly increasingly faster due to the air getting thinner, without the display screen following this fact. At approx. 6,500 m the air weighs only half of that at sea level, therefore the air speed will increase by 1.41 times (as a radix of 2).

- 46 -

Operating Manual Flytec 6020

The physics could be pictured as follows: In order to create a certain lift a certain number of air particles need to hit the airfoil. Because of the fact that at 6,500 m altitude there are now only half as many particles present per meter, the wing surface has to fly faster, but not twice as fast, because each particle has a higher striking energy and is then only 41% faster. However, for the calculation of wind, arrival altitude or arrival time at goal, the true air speed values are always required. The wind wheel sensor shows the true air speed (=TAS), because it runs practically without friction. The Flytec 6020 GPS indicates generally the true air speed - TAS.

9.2.2 Stall alarm

If a pilot slows down his glider gradually, he will cause a stall when falling below a certain speed, which will have different consequences, depending on the type of aircraft. If the air current is suddenly cut-off from the entire surface, then a completely unforeseeable crash would be pre-assigned. For this reason, our airfoil manufacturers are building a so-called cross-setting into the support parts of the wings; this means that during flight the wing tips will always have a smaller stalling angle than the middle part of the glider. If the air flow stalls in the middle part of the surface when falling below a minimum speed, then lift still remains on the wing tips. The aircraft is now in the so-called descending or stall. Due to the fact that the wing tips are positioned behind the aircraft’s centre of gravity, the aircraft will independently drop nose downwards and try to increase the air current by gaining speed.

It is certainly to misadvise to remain a longer time span in this excessive flight situation, as the wing will react extremely sensitive to even minor air turbulences. A stall can be dangerous, especially during the landing approach. The consequence could result in a stall over one surface or a non intended 180-degree curve. The stall alarm is a loud, concise acoustic signal that requests the pilot to fly faster. It assists first and foremost hang gliders, however para gliders to a lesser extent. Anyone who has ever watched a hang glider come in during an approach can observe the following situation: always when a good headwind prevails, many pilots will pull out their steering bar too early; the glider then climbs a few more meters to end up in a favourable case afterwards with its keel stuck in the ground. With no wind or with a light tail wind most pilots wait too long to pull out the bar. In this case, and with any luck the result will only be a belly landing; but also a ground-loop with broken base side tubes may be the result, or the glider’s nose absorbs the impact energy when touching ground and the pilot will swing pendulum wise, hitting his helmet on the front keel tube.

There are different stall speeds to apply for each glider and varying weight of the pilots. Several tests are necessary to determine for the own arrangement the setting of correct stall alarm limit in Main Setup Menu it is worth to note that close to the ground, and because of the air cushion under the wings, the stall occurs at approx. 2 km/h lower speed than in the high air.

However, stall speed also depends on the specific weight of the air, meaning: the flight altitude. On the 6020-GPS the stall alarm level is automatically raised with increasing flight altitude, corresponding precisely to Indicated Airspeed. It is unimportant if the pilot has selected True- or Indicated Airspeed for the speed display screen.

The border limit between stall alarm and the speed for minimal sink is indeed very small. Hence several pilots have complained about the fact that while circling up in weak thermals at the speed of minimal sink, the stall alarm is triggered sometimes. In this regard there is

Stallspeed above which the stall alarm shall not be initiated. In this case naturally, the landing areas should be located below this limit.

9.3 Navigation

9.3.1 Reception quality of GPS

The GPS-Receiver can follow up to 16 satellites simultaneously. After turning on the unit it is necessary to receive at least 4 satellites to fix position for the first time. Once logged on, 3 satellites (for 2D positioning) are sufficient for further position finding. However, if altitude recording is also required (3D positioning), then definitely 4 satellites are required. There is a table in the receiver, The Satellite Almanac, in which the path, place, and time of all satellites are kept with reference to the receiver. The Almanac is continuously updated during signal reception. However, if the signal to the Almanac memory is disrupted completely or the unit is taken 200 km or more from the last reception point, then the Almanac has to be re-established. Power is still supplied to the almanac’s memory even when the unit is turned off.

Normally the instrument recognizes its position under unobstructed view condition after a few minutes. If the receiver is switched-off for a short time (less than 2 hrs.), the time for new position finding is less than a minute. Buildings, mountains or thick forest affect reception quality of the receiver. Therefore, you should always look for the best possible visibility around you and the antenna in the casing should point upwards if possible. In particular when mounted on the steering bar of the hang glider, we recommend not to have the instrument fixed under the pilot’s head on the middle of the basis, but indeed sideways. In this position the 6020-GPS should not have more than 45° deviation from horizontal position so that the antenna points upwards. Due to the fact that receiving strength of the satellite signals is only approx. 1/1000 of mobile radios, these radio sets and other disruptive factors (like notebooks) should be operated as far away as possible from the 6020-GPS. The 6020-GPS is fitted with a 16-channel GPS-Receiver which is featured with lesser power consumption and also a significantly shorter satellite detection time. Precision is between 7 to 40m. As an average one may assume approx. 15 m.

9.3.2 Accuracy of GPS altitude

A good explanation of GPS accuracy is found on the following website:

http://www.kowoma.de/en/gps/errors.htm

First of all the term accuracy has to be defined: On the website above you can read: “The declaration of the accuracy by Garmin GPS receivers sometimes leads to confusion. What does it mean if the receiver states an accuracy of 4 m? This readout refers to the so-called 50 % CEP (Circular Error Probable). This means that 50 % of all measurements may be expected within a radius of 4 m. On the other hand it also means that 50 % of all measured positions are outside of this radius. If one assumes a standard dispersion, then 95 % of all measured positions are within a circle of twice this radius, thus 8m, and 98.9 % are within a circle of 2.55 of the radius, thus in this case within 10 m. “

- 48 -

Operating Manual Flytec 6020

Satellite orbit radius =26560km

Earth radius =6360km

The position is derived from a triangulation. The GPS receiver measures the time of the signals and calculates the distance to the respective satellite by taking into account the speed of light. Based on three satellites the horizontal position can be determined, and with 4 satellites the spatial position with altitude. You can find a good explanation of the involved calculation on Wikipedia.

For a spatial position determination (3D position) there are needed 4 satellites, one satellite is hereby required for synchronisation.

In case of a 3D position identification, best accuracy is achieved if the 3 satellites are 90° to each other. In this case the volume of the spanned pyramid is the biggest. Again the DOP (Dilution Of Position) is the inverse value to the volume of this pyramid.

For a good 2 D position on the earth surface it is best, if you have 2 satellites at 90° near the horizon. So for example, one to the North, the other one to the East. The 3rd satellite vertically above the position does not contribute to accuracy, it just gives a rough information of the altitude, but which is good enough for a good lat/long determination.

90°

4th Satellite for time Synchronisation

Best Accuracy is achieved if the angle between 2 satellites is 90°. The spanned triangle between one’s own position and the two involved satellites then has the largest possible surface area. The unit DOP (Dilution Of Position) is proportional to the inverse value of this area

- 49 -

Operating Manual Flytec 6020

Almost no time difference Satellite 2

The chance to find 2 satellites near the horizon being at 90° apart, is better than to find 3 satellites with 90° to each other directly above the actual position.

Because the circumference area above the horizon is larger than the area perpendicular above the position, and assuming that the satellites are nearly equally dispersed, there is a bigger chance to find convenient satellites near the horizon. The GPS module will therefore prefer satellites near the horizon. For determination of the horizontal position, the module will calculate any combination of the visible satellites to make an average of these combinations every second. To do the same with the vertical position, the receiver would need twice the calculation power. Due to the fact that motor vehicles and pedestrians normally require the horizontal position, one saves the effort by computing altitude from the best combination and generates the average by time. This is an explanation of the lower accuracy and the run after or delay of the vertical position.

The GPS module of the Flytec instruments does not perform a timed filtering over the horizontal position, but in case of good reception quality it does a filtering over approx. 5 s for the vertical position. The poorer the GPS-reception, the longer this time constant.

9.4 Flight optimisation

9.4.1 Final glide calculation

Here the GPS-Data and the McCready theory go hand in hand. Principally it is about reaching a goal (of course it must be logged as a waypoint in the list) as fast as possible, or rather, to get a signal from the instrument of when the last thermal can be left in order to arrive at the WP as fast as possible. In order to be able to establish a statement about this, the distance to this location must be known. This distance will be calculated with help of the GPS-Receiver. In addition, we need the altitude of the waypoint (is mentioned in the list of waypoints), as well as the current altitude of the pilot. From this smallish amount of information it is possible to calculate the required glide ratio over ground (L/D req.) which is necessary to reach the goal. For this purpose all other conditions, such as climb, sink, wind and wind direction, flight speed and polar curve, are left entirely unconsidered. The required glide ratio can be displayed in the user defined fields: L/D req. It is only when the flyable glide ratio (over ground) has to be determined, that the before mentioned conditions have indeed an important role.

Basically the final approach consists of two phases which are to be considered separately:

1.) climbing in the last thermal and

2.) the straightest possible glide path to the goal.

The Flytec 6020 does not calculate with the McCready theory, but only with the speed of best glide. In order to reach the goal under optimal conditions all the same, the pilot can take nonetheless some decisions based on the final glide display screen, which will help him to reach goal safely in the shortest possible time. For this purpose it is helpful to keep part of the McCready theory at the back of one’s mind. The McCready theory declares that one is flying time optimised if, after having left the thermal, one would be flying as fast as one would be in a descending air mass at the same speed as would be the day specific climb in the thermal. This speed value has to be calculated from the polar curve and the resulting figure is the speed to fly. Given the fact that the 6020-GPS does not compute with the polar curve, one needs to estimate this „optimal“ speed by himself.

1.) Let’s assume that the pilot is circling under a cloud in quite a good thermal which provides to him an average climb of 2 m/s. While circling he will naturally try to fly with the speed for minimum sink. If, while circling, the nose of the aircraft turns again and again in the direction of the goal, the wind component, and, derived from this the wind factor, may be determined at this moment and consequently the glide ratio over ground (Gnd) can be calculated. From the distance to goal and the glide ratio (gnd) the 6020-GPS calculates the loss in height which the pilot requires on his glide path to the goal. If the altitude of the goal is added (for each WP also its altitude is saved), then we obtain directly the minimum departure altitude. The own altitude is known, therefore the instrument can now display directly by comparison at which altitude is reached the path of best glide and if we still have to thermal up to arrive safely. It is of course subject to the pilot’s experience whether he wants to take-off immediately upon positive „Diff. BGWayp“, or whether he will prefer to climb up further and take some reserve altitude. The 6020-GPS naturally does not know whether in the course of the glide path lifting or sinking air mass zones are incorporated, or if the wind intends to change. The instrument calculates with the current wind and assumes that no lifting or sinking zones are to be expected.

- 51 -

Operating Manual Flytec 6020

On the one hand one will climb for safety reasons somewhat above the path of best glide. On the other hand one will climb still slightly higher on a day with good thermal and then slowly annihilate this reserve altitude when gliding down by flying faster with consequently earlier arrival.

2.) Gliding down to Goal The pilot has left the thermal with sufficient safety altitude above the path of best glide and is flying towards his goal. He should speed-up until the display „Diff.BGWayp“ will begin to decline slowly. This display indicates that by flying faster, one is annihilating slowly the altitude reserve. However, one should look out for sinking air mass or head wind. This is shown when the display „Diff.BGWayp“ is declining more quickly and when the paraglider symbol on the final approach display screen is moving faster towards the intersection. In this case it is recommended to fly at a more slowing rate again.

For all previously made considerations we assumed that the wind component is automatically calculated from the difference: good reasons which justify to overwrite this automatically logged

1. While circling up in thermals the wind prevailing outside of the thermal shall always

be stronger than the measured one. The strength is dependent on the value of climb and also on the fact if the pilot is at the top or at the bottom of the thermal.

2. As for the final approach, also slight wind fluctuations, for ex. when induced

by yaw will take effect on the pre-calculated arrival altitude. A wind component logged as fixed value shall then calm the result.

3. When the pilot being in down glide from high altitude knows by experience,

in which way the wind shall change in the lower layers, he can consider this already in advance.

4. When para glider pilots fly without speed sensor, the manually logged wind

component can provide a significant improvement of final glide calculation.

9.4.2 Safety altitude (Alt a. BG)

The display „Alt a. BG“ indicates the pilot’s current altitude above (or below) the path of best glide leading to goal. The safety altitude (Alt. over Alt a.BG) is also this altitude which one could safely lose when flying through a sinking air mass and could still make it to goal. „Alt a. BG“ can also be shown continuously in the user selectable fields. It is only then identical to „Alt a. WP“ if the pilot flies with the speed of best glide. The fields „Alt a. BG“ and „Alt a. WP“ will switch to inverse display during thermal circling at the moment when the pilot could leave the thermal (Alt a.BG) in order to just arrive safely; or when the pilot should definitely leave the thermal (Alt a. WP) in order to reach the selected WP as fast as possible. (see picture on page 17).

9.4.3 Final Glide calculation over several Waypoints

As of the 6020-GPS a new user selectable field „Alt a. Goal“ has been added. This is a pre-calculation, based on Route, irrespective of how many WP’s are still in front of the pilot. The related actual wind vector is taken into account for all sectors, as well as the differing glide ratio values resulting from it. Naturally this result requires that the detected wind does not change on the way to goal. The wind vector is updated again by each flown full circle

best glide ratio, of required altitude above (or below) the last WP of a

Gndspeed – Airspeed. However, there are

Spd-Diff with a manually entered value.

9.5 Flight Memory and IGC File

9.5.1 Content of IGC Files

In the IGC File are saved all important data of a flight in readable format. One can open the IGC File by using any desired Editor. Though editing or modifying is possible, the signature at the end of IGC File shall be changed to invalid. This signature is calculated over all data and therefore covers the flight, as well as

the pilot’s personal data and the date. The signature is generated by the instrument. The misapplication is therefore practically excluded.

Sometimes it is helpful if one can import to Excel the raw data being stored in the IGC File in order to practice own calculations.

Please proceed as follows: In Excel program click on open / file Select file type all files. Follow the 3 Import steps.

Set the arrows for column disjunction as follows:

- 53 -

Operating Manual Flytec 6020

Select standard format for columns

The present head in lines 1 – 13 contains internal flight data. These are no longer required and can be erased.

For better understanding content and unit of columns are captioned.

The columns now have to be set into the configuration required by the Software Caution: the coordinates are in XX°XX.XXX’ format. Therefore the number 4619616 should be read as 46 degrees 19.616 minutes, which corresponds to 46°19’39.96“.

More information in regard to IGC Format is available on the FAI Website under:

http://www.fai.org/gliding/gnss/tech_spec_gnss.asp

9.5.2 New Regulations for Record flights or decentralised Competitions (OLC) Since the evidence of a completed flight depends entirely on the GPS recording, it is

important to ensure before take-off that the GPS-receiver indeed receives satellite signals. Therefore please switch-on the 6020-GPS at least a few minutes before take-off so

- 54 -

Operating Manual Flytec 6020

that even pre-flight events are included in the recording. The Barogram is also included in the IGC-File which is generated for each flight.

Photographic evidence and confirmation by flight observers are no longer required for national performance flights. The file can be sent directly to the judging committee of the OLC via the Internet. (at present, the OLC is evaluated in Germany by the DHV).

9.5.3 Evidence of flights - Safety against Manipulation

The FAI (Fédération Aéronautique Internationale) and its subgroup IGC (International Gliding Committee) require a recording format which, while memorizing continuously the time of day, position and also the flight altitude, and therefore substitutes the barograph. When transmitting flight data to the pilot’s PC, a so-called IGC-File is created, which receives a digital signature (=G-Record) authenticating the flight data and making it fraud-resistant. If only one character of the file containing the flight would be changed, the signature would no longer be compliant to the data and the judging committee would be aware of the manipulation.

9.5.4 Digital Signature and OLC- Registration

The popularity of decentralized competitions has been growing enormously over recent years. Meanwhile 26 countries have accepted the OLC (Online Contest) convention. These agreements state that any pilot can submit flights at will over the Internet for approval and evaluation. The submission has to be compliant to IGC-format (WGS84) and must have a digital signature. In order to facilitate further on the utilisation of usual GPS-Receivers, relevant PC-evaluation programs such as Compegps, Gpsvar, Maxpunkte or Seeyou calculate a digital signature to allow submission of flights in the required form. However, a “signature” created by PC provides only half the safety against falsification. In the long term this signature shall be mandatory to be provided by the GPS-Recorder instruments, as for ex. the 6020-GPS.

After completion of a flight, effected automatically or manually, this „Digital Signature“ is calculated autonomously by the 6020-GPS and added to the flight data file as so-called G-record. A correlative remark „Generating Digital Signature“ is displayed in the info field of the instrument. As this calculation is extremely complicated, it may take several minutes following a long flight with setting of a short scan rate. Please wait until this message will disappear.

Should it once happen that the OLC does not accept the digital signature upon the transfer of flight data, the signature can be recalculated on the flight analysis display, by pressing the

key

Recalc Signature „Rec Sig“.
