2 GETTING STARTED
2.1 CONNECTIONS
The mini USB socket provides the battery charge and the link to a Personal Computer. Micro SD card slot. Bluetooth connection.
2.2 BATTERY
The main power is supplied by an internal rechargeable high capacity lithium battery. This battery has no
memory effect, so it can be partially recharged, without affecting the battery’s time life. It also has a very low
self-discharge rate (more than one year) and works very well at low temperatures. A fully charged battery life
ranges over 30 hours.
When the battery’s icon starts to blink there are roughly 4 hours use remaining.
2.2.1 BATTERY RECHARGE
To recharge the instrument insert the charger plug or other mini USB accessory and wait till the battery level
indicator is totally filled.
The required time for a full charge is about 8 hours. There are no problem if you leave the vario charging for more than 8 hours, as the vario automatically
switches to a “maintain mode” to prevent the battery’s overcharge.
The Digifly AIR’s lithium battery has no “memory effect”, so it can be also partially charged.
2.2.2 EXTERNAL POWER SUPPLY
The mini USB socket can be used to power the instrument and simultaneously charge the internal battery for
unlimited time.
With the instrument turned on, it is necessary an external stabilized 5VDC power supply (e.g. a solar panel)
and a minimum of 150mA to properly power the instrument. The exceeding electric current will be used
charge the internal lithium battery. Proper solar panels are suitable to power the instrument.
2.3 KEYBOARD - NORMAL OR LONG KEY PRESS
The time length you press the keys on your Digifly instrument selects the available functions. Normal press key means to press the button for less than a second For a long key press, you must keep the button pressed down for at least 2 seconds When not specified, the key press has to be considered as a normal key press (less than a second).

4.2.3 GRAPHIC ALTIMETER
In the COMPASS page, the altimeter’s digital information is integrated with a
graphic sliding scale. This scale is intuitive to be understood and feature a
numeric indication of the 500 and 1000 m altitude’s gap in a graphic design that
enables, at a glance, a visual distinction of the height. It features also a simple
graduated scale for the hundreds meters.
4.2.4 COMPASS SCREEN ESSENTIAL INSTRUMENTS
In the COMPASS page the essential flight info are simply shown aligned in a
raw.
Aligned with the digital variometer you can find the altimeter A1 value, the
current glide ratio and the Indicated Air Speed (if the optional pitot tube is
installed) or the GPS ground speed
4.2.5 PLOTTER PAGE ESSENTIAL INSTRUMENTS
In the PLOTTER page, the essential info are slightly different from the compass
page, to allow the availability of a larger amount of info for the navigation.
Aligned to the digital variometer, on the display’s opposite side is located the
IAS/GS indicator, while the altimeter A1 and the glide ratio are positioned on the
left-upper side of the display.
Page 14
4.2.6 NAVIGATION PLOTTER SCREEN
In the PLOTTER page the navigation is based on a graphic perspective plotter that
features:
o Graphic representation of the flight track toward the current WP; o Graphic representation of the current WP cylinder; o Optimized course line to the current WP cylinder; o Optimized course line to the next WP; o Wind’s direction and intensity;
The following info are listed in digital format:
o Required glide ratio to the current WP and its distance; o Expected height of arrival above the Current WP and current glide ratio; o Current WP name.
4.2.7 HSI NAVIGATION PLOTTER PAGE
In the center of the PLOTTER page are represented two dotted lines crossed,
where the crossing point indicates the current WP with its real altitude. During
the glide to WP the “plane” symbol, moves toward the right or the left of the
vertical dotted line to indicate a wrong route to the cylinder’s center and moves
above or below the horizontal dotted line to indicate if with the current glide will
arrive above or below the WP.
Along the horizontal line, the symbol represents the optimized direction to the current WP.
4.2.8 BEARING COMPASS
On the bottom of the PLOTTER page there is a bearing compass showing also all
the navigation’s info with graphics symbols (WP direction, wind etc.…).
If the GPS signal is valid, the direction is the TRK of the GPS track, otherwise it is
represented the AIR’s internal magnetic compass.
COMPASS SCREEN MAIN FIELDS
In the COMPASS page, the navigation info are represented with a series of
concentric circles with some rotating symbols:
- Outside the circle there are the N-E-S-W points;
- In the outer ring are rotating the direction to WP symbols;
- In the inner ring are rotating the direction to the last thermal, the wind direction
and wind speed symbols.
4.2.9 COMPASS SCREEN, NAVIGATION TO THE START LINE
In the COMPASS page, during the task’s phase preceding the Start, the pilot finds some
specific info to navigate to the Start line.
On the top section there is a clock and below a field with the countdown timer to start.
Page 15
Below the glide ratio indicator is shown the distance of the Start Line closest to the pilot and its direction. After the Start and once correctly passed the Start line, these fields can be optionally used for other info on
pilot’s choice.
5 BASIC FUNCTIONS
5.1 ALTIMETERS
The Digifly AIR features 7 different altimeters: A1, A2, AG, A3, H1, HA.
- A1: Barometric altimeter.
- A2: Altimeter A2.
- AG: Altimeter GPS.
- A3: Last thermal height gain
- H1: Estimated height over current WP
- HA: Estimated height over goal.
5.1.1 ALTIMETERS SETTINGS
Enter in the “ALTIMETERS” menu and select which altimeter to set (A1 or A2). The A2 altimeter is suitable for general purpose. To reset the A2 altimeter hold pressed the key from the
PLOTTER or COMPASS pages;
The A3 altimeter is automatically reset while entering in a thermal. The altimeters can be displayed in meters (mt) or feet (ft). To change the altitude’s unit of measure enter the
setup from (MAIN SETUP \ n. 15 U-AL).
5.2 VARIOMETERS
5.2.1 SUPERFAST INTELLIVARIO
The Intellivario is a revolutionary digital system designed by Digifly, based on sophisticated integrated circuits
combining info coming from the atmospheric pressure sensor joined with the inertial platform data
(accelerometer, magnetometer and gyroscopes). This allows to obtain a highly precise and sensible vario,
exempt from radio interferences. All the vario data are subject to this filter.
The Digifly AIR utilizes an extremely sensible pressure sensor and an excellent data acquisition sys providing a
very quick and extremely precise vario (updated 24 times each second).
5.2.2 VARIO SENSIBILITY
Three different electronic filters are available to change the vario’s sensibility. These settings allow the pilot to
get a strong instrument’s customization, to better adapt it to his flight habits and needs.
Filter 1, adjustable in the menu (VARIOMETER SETUP \ n. 10 FLT1), default value 80% , suggested use range
from 70% to 95%, reducing this value makes the vario very sensible to variations.
Filter 2, adjustable in the menu (VARIOMETER SETUP \ n. 11 FLT2), default value 72, suggested use range
Page 16
from 48 to 96, reducing this value makes the vario very sensible to variations.
Filter 3, adjustable in the menu (VARIOMETER SETUP \ n. 12 FLT3), default value 0%, suggested use range
from 0% to 10%, reducing this value makes the vario very sensible to variations.
5.2.3 VARIO REACTIVITY
To adjust the vario’s reactivity, enter in the menu: (VARIOMETER SETUP \ n. 13 RVAR). The default value is 0.
To slow the reactivity, increase this parameter.
5.2.4 ANALOGICAL VARIO
Indicates the instant vario values. It is displayed by the analogical bar indicator on the left of the screen, it
shows the sink or climb rate within a +/- 5 m/s range.
5.2.5 INTEGRATED AVERAGE VARIO
Shows the integrated vario values. This means an average data reading (slowed down in the time) of the
instant vario.
Can be set slowed down or immediate. Setting to the minimum the integrated vario value, the shown value
will be the same of the instant vario (factory setting).
It can be used to monitor the proceeding of the climb to see if it is getting better or worse. For example: if the
integrated vario value is higher of the instant vario one, means that previously the climb was stronger. It can
be used therefore to better core the thermal.
To change the integration time, set the parameter: (VARIOMETER SETUP \ n. 14 INTE) from 0 to 60 seconds.
It is analogically displayed on the right of the instant variometer, with a bar showing the climb or sink rate with
a range +/- 5 m/s. During the glide the gauge alternates with the “NETTOVARIO”.
5.2.6 ACOUSTIC VARIO
The acoustic vario represents the instantaneous values of the vario with a modulated acoustic tone. Pressing the key (long pressure) the sound’s volume changes into three levels: “HIGH”, “OFF” & “LOW”.
The chosen volume is shown by the ‘loudspeaker’ icon on the center left of the display.
To set the sound’s threshold level to indicate lift, go to parameter (VARIOMETER SETUP \ n. 1 V.UP), for the
sink, go to (VARIOMETER SETUP \ n. 3 V.DN).
It is possible to set the preferred acoustic profile with the parameter (VARIOMETER SETUP \ n. 4 PROF). Three
pre-set profile are available: FAS, STD, SFT, Two fully customizable profile: USR1, USR2 are available via PC
using the AirTools software; moreover, there is a new manual ‘MAN’ mode, that allows to directly customize
the instrument using the following parameters.
Style, (VARIOMETER SETUP \ n. 5 STYL) relation among sound/pause, values from 1 to 3. Modulation, (VARIOMETER SETUP \ n. 6 MODH) increases the tone frequency from 1 to 30 Hz. Pitch, increases ascending the tones rhythm (VARIOMETER SETUP \ n. 7 PITC) values from 1 to 4. Climb start tone’s frequency (VARIOMETER SETUP \ n. 8 UPHZ) Sink start tone’s frequency (VARIOMETER SETUP \ n. 9 DWHZ) Autosilence, (VARIOMETER SETUP \ n. 19 AUTV) activates the acoustic vario only after the takeoff and stops it
Page 17
60 seconds after the landing.
5.2.7 ACOUSTIC VARIO PRE-THERMAL ADVIDSE
If activated, an acoustic signal with a tone and modulation significantly different of the acoustic vario,
indicates that the instantaneous sink rate is better of the glider’s minimum sink rate, therefore indicating an
area of slightly climbing air. To set the pre-thermal sound’s start threshold go to: (VARIOMETER SETUP \ n. 2
V.PT) value from 0,00 to 1,00 m/s. Suggested value 0,4 m/s.
5.2.8 VARIO SIMULATOR
For a perfect tuning of the acoustic vario without flying, it is possible to set the ‘vario simulator’ mode, setting
“ON” the parameter (VARIOMETER SETUP \ n. 18 SIMV). Then exit from menu and use the arrow keys
to set the preferred vario sound.
To deactivate the simulator set to “OFF” the parameter “SIMV”. Anyway, for safety reasons the simulator is
automatically deactivated when the instrument power on.
5.3 AIR SPEED (ANEMOMETER WITH OPTIONAL PITOT TUBE)
This sensor measures the glider’s air speed (Indicated Air Speed) that can be visualized in km/h or mph. To
change this parameter use the menu (MAIN SETUP \ n. 16 U-SP).
This function is available only installing the Pitot tube sensor module (optional). The tube will have to be
inserted in the specific housing hole located on the instrument’s top, and the parameter (ADVANCED SETUP \
n. 1 PITO) have to be set to “ON”.
The minimum speed indication is 18 km/h.
5.4 ANEMOMETER SETTING (WITH OPTIONAL PITOT TUBE)
It is possible to perform a fine tuning of the anemometer using the parameter (ADVANCED SETUP \ n. 3 KIAS)
it indicates the anemometer’s correction value (100%=no correction, 110%=increase, 90%=decrease).
Warning: a wrong use of this parameter makes less reliable the anemometer’s indications, the calibration of
the anemometer with the Pitot tube should have done at the sea level in standard atmosphere conditions.
5.5 TIME & CHRONOGRAPH
The Digifly AIR can visualize the expected hour and time referred to a route’s waypoint, or a goal arrival. Relative time (hour/min or min/sec with blinking points)
- ero: relative time – expected arrival time to the start pylon cylinder shown in seconds. Negative value if it’s
too early (wrong), positive value if it’s late (right).
- es: countdown to the start time gate
- e1: expected arrival time to the current Waypoint
- eA: expected arrival time to the goal (accordingly to the route)
- ch: chronograph
Page 18
Absolute time (hour/min)
- ts: absolute time to start pylon gate
- t1: Expected absolute time to the current Waypoint.
- tA: Expected absolute time to goal.
- rt: Absolute time UTC (hours/min).
5.6 DISTANCES
It is possible to set the distance’s unit of measure using the parameter (MAIN SETUP \ n. 16 U-SP) the same
used also for the speed value.
- dstT: Distance to last thermal.
- dst1: Distance to last Waypoint.
- dstA: Distance to goal (along the route).
- dst0: Distance to the cylinder
5.7 AIR EFFICIENCY (GLIDE RATIO)
- efrT: Needed glide ratio to the last thermal.
- efr1: Needed glide ratio to current Waypoint.

- BR1: Direction (bearing) to the optimized point of current Waypoint.
- TRK: Tracking (current direction referred to North)
5.9 BAROMETER
The barometric pressure can be visualized on every one of the customize fields. It is possible to rectify the shown pressure value modifying the calibration with the parameter (ADVANCED
SETUP \ n. 4 KBAR).
Warning: a wrong use of this parameter makes the barometric altimeter data less reliable.
5.10 TIME/CHRONOGRAPH SETUP
rt: UTC time (clock). ch: Chrono (chronometer).
To zero the chronograph, press the (long press).
Page 19
The vario time and date are automatically synchronized with the GPS data at the instrument’s power on. To set the time zone for your country go to (MAIN SETUP \ n. 7 UTCO). To manually adjust the time and date, go to (MAIN SETUP \ n. 8 HOUR), (MAIN SETUP \ n. 9 MIN), (MAIN
SETUP \ n. 10 DAY), (MAIN SETUP \ n. 11 MONT), (MAIN SETUP \ n. 12 YEAR).
5.11 PILOT’S NAME & GLIDER’S DATA
To set the pilot name, the glider type and the glider id, go to (MAIN SETUP \ n. 17 PILO), (MAIN SETUP \ n. 18
GTYP), (MAIN SETUP \ n. 19 GID).
6 ADVANCED FUNCTIONS
6.1 TOTAL ENERGY COMPENSATION
To use this function it is necessary to install the optional Pitot tube. Generally a variometer works as follows: it feels the atmospheric pressure change rate considering it as an
altitude change, but, if during the flight the pilot slows the glider (and even more if he does it quickly) there is
a real change of pressure, so a vario ‘without compensation’ records it as a climb, but this variation is caused
by a change of speed (cinetic energy) not a true thermal.
With the total energy compensation, the part of the climb due to the change in velocity is ignored, allowing you
to identify “real” thermals.
To properly set the TOTAL ENERGY
compensation value go to (VARIOMETER
SETUP \ n. 17 TEC), to do it you should fly in
calm air conditions and slow down as if you
are entering a thermal. If the vario shows a
change in lift, you have to increase the total
energy compensation value, until the
change in velocity isn’t recorded as lift.
A typical value for hang gliders is 65. The default setting of “0” deactivates the total energy compensation
function
6.2 POLAR (WITH OPTIONAL PITOT TUBE)
A polar curve (shown in bold on the figure) is the graph of
your glider’s sink rate over its speed range.
The black bold curved line represents the polar. The
glider’s stall speed is shown at point S on the left and the
glider’s max speed at point T on the right of the graph.
On the graph, you can also see three pairs of relative
speed readings and sink rates. The graph shows at point A,
the lowest sink rate achieved at the top of the curve.
Therefore SinkA is the minimum sink rate and VA is the speed at which this is achieved.
Page 20
The glide ratio is the ratio between the glider’s horizontal speed and the sink rate. To find the best glide rate
on the graph, it is necessary to draw a straight line from the origin of the graph (point O) tangent of the curve.
The intersection of the tangent with the curve (point B) shows the speed to fly at to achieve the best glide (air
related) is therefore VB and the glide ratio is VB/SinkB.
On your Digifly AIR you can insert three different polars using the function (ADVANCED SETUP \ n. 10 - 18 Px-
A/B/C). To choose which polar to use, go to (ADVANCED SETUP \ n. 9 POLA).
If this parameter (ADVANCED SETUP \ n. 6 POLA) is set to “OFF”, all information relating to McCready,
McCready Equivalent, and Netto Vario are not displayed on the instrument.
On the instrument there are three preloaded polars, (2 for hang gliders and 1 for a paraglider). Using the
Digifly AirTool software, available on the Digifly web site (www.digifly.com), it is possible to see the values of
the three default polars and to set your own polar.
We suggest that you insert your own polar curve data which best reflects the actual performance of your
glider.
6.3 SPEED TO FLY (WITH OPTIONAL PITOT TUBE)
If this parameter (ADVANCED SETUP \ n. 9 POLA) is set to “OFF”, all information
related to McCready, McCready Equivalent, and Netto Vario are not displayed
on the instrument.
Speed to Fly (STF) is the best anemometric speed to obtain the best glide ratio.
This value depends on performance of your glider as well as vertical and
horizontal airflow. In calm air, the optimum flying speed is the same as the best
glide speed (point B).
The diagram shows different values of speed to fly value related to different
flight conditions
The X-axis shows horizontal speed, the Y-axis shows sink rate. With head wind or sink conditions, the best
glide speed increases. In order to find the optimum speed to fly value in sink conditions, add the sink rate of
the air to the polar of your glider, drawing a new polar and a new tangent line from the initial point of axes.
The new tangent (point D) meets the polar at the point giving a higher optimum flying speed VD.
To fly at the correct “Speed to fly” you have to adjust your anemometric speed “IAS” to overlap the triangle
symbol with the numeric value of the optimal anemometric speed.

6.4 McCREADY (WITH OPTIONAL PITOT TUBE)
If this parameter (ADVANCED SETUP \ n. 9 POLA) is set to “OFF”, all
information related to McCready, McCready Equivalent, and Netto Vario are
not displayed on the instrument.
The McCready value is the average lift value of the last “nn” minutes To adjust the average lift time go to (ADVANCED SETUP \ n. 19 MCRA).
6.5 EQUIVALENT cCREADY (WITH OPTIONAL PITOT TUBE)
If this parameter (ADVANCED SETUP \ n. 9 POLA) is set to “OFF”, all information related to McCready,
McCready Equivalent, and Netto Vario are not displayed on the instrument.
This value indicates the Equivalent McCready value: this means the McCready value considering the current air
speed as the optimal speed.
The equivalent McCready, based on the glider’s polar, the sink rate and the current anemometric airspeed
(IAS), indicates in real time at with which true McCready value we are flying compared to the optimal speed.
When this value coincides with the one estimated in the thermal, this means that the current airspeed (IAS)
coincides with the optimal speed (see “speed to fly” paragraph).
To set the reaction time of the Equivalent McCready indicator go to (ADVANCED SETUP \ n. 20 MCRE).
6.6 NETTO VARIO (WITH OPTIONAL PITOT TUBE)
If this parameter (ADVANCED SETUP \ n. 9 POLA) is set to “OFF”, all information related to McCready,
McCready Equivalent, and Netto Vario are not displayed on the instrument
It is shown thru an analogic scale on the right of the instant variometer that shows the climb or sink rate
within a range +/- 5 m/s. This indicator, during the glide, alternates with the “NETTOVARIO”.
To use this function it is necessary to set the proper polar of your glider.

7 GPS FUNCTIONS
7.1 INTEGRATED 99 CHANNELS GPS RECEIVER
Digifly AIR features an extremely sensible, and state-of-the-art, 99 channels integrated GPS receiver.
7.2 GPS STATUS INFORMATION
The GPS status icon is located in the status bar, on the right lower part of the display (plotter screen) or on the
lower edge of the display (compass screen) and has different meanings:
1) Fixed GPS icon = GPS FIX valid ( GPS position available)
2) Blinking GPS icon = insufficient signal (GPS position NOT AVAILABLE)
7.3 GPS INFORMATION DISPLAY
This page shows in real time: Waypoint and symbol, Latitude,
Longitude, GPS direction (“TRK”), Ground speed (“GS” in km/h or
mph), GPS Altitude (“GPS-ALT” in mt or feet), Satellite’s number
(“SAT”), GPS Signal power (“hdp”).
In the status bar is visible also the flight recorder status and the
battery level
Pressing the key (long pressure) it is possible to memorize a
Waypoint (“MARK” function), holding pressed the key activates the
navigation function “HOME”.
7.4 LATITUDE & LONGITUDE COORDINATES OPTIONS
Three different kinds of coordinates are available:
DMS = grade, minute & second (dd° mm’ ss.s) (default)
DMM = grade & minute (dd° mm.mmm’)
UTM Universal Transverse Mercator (utm x, y, zone).
To set the coordinates DMM, DMS or UTM use the parameter (ADVANCED SETUP \ n. 23 CORD).
The coordinates latitude and longitude are referred to map datum WGS84.
7.5 GPS ALTITUDE
The GPS altitude is the height above the sea level accordingly to the satellite system (“AG”), it is visible in the
page GPS INFO.
7.6 GPS GROUND SPEED
The GPS ground speed is the glider speed related to the ground (“Gs”). When a navigation is activated, the ground speed is visualized in reverse mode if the glider is moving away
from the waypoint.

Page 23
7.7 GPS DIRECTION (TRK)
The GPS direction (“TRK”) is the glider’s direction related to the ground.
7.8 GROUND EFFICIENCY (GLIDE RATIO)
It shows the efficiency (glide ratio) related to the ground. To set the time over which the average efficiency (glide ratio) is calculated, go to (ADVANCED SETUP \ n. 7
EFF).
If the “ground speed” slows below the 2km/h or the GPS signal is not valid, the indicator shows: “ 0.00 ”. If you are in lift, the efficiency indicator is in reverse mode and shows the average efficiency calculated during
the last glide, go to (ADVANCED SETUP \ n. 8 EFFA) to set the time to be used to calculate the medium
efficiency (glide ratio) to be used for the glide calculation to WP
The average efficiency value is very important because it is the value used by the glide computer.
7.9 WIND SPEED AND DIRECTION INDICATION USING GPS
The wind speed and its direction are automatically computed and displayed using the direction info coming
from the GPS (“TRK”) and the “ground speed (“Gs”).
To determine the wind speed and its direction, you should make a “normal” turn, which has to be neither too
tight, nor too wide.
It is also important to maintain constant airspeed during the turn. For an accurate calculation, a 360º turn must be completed. The wind direction related to the glider and its speed are visualized in the both main screens COMPASS and
PLOTTER.
This function uses the parameter (ADVANCED SETUP \ n. 22 WSEN) for the wind calculator sensibility (default
WSEN = 5)
7.10 LAST THERMAL DIRECTION, DISTANCE, HEIGHT INFORMATION
The data: direction “brt”, distance “dst T” and altitude gain “A3” are shown on the display when it is detected a
thermal.
To define a thermal, this function uses two parameters: the variometer value (VARIOMETER SETUP \ n. 15
THEV) to define the vertical speed (vario), and the lift’s minimum duration in seconds (VARIOMETER SETUP \ n.
16 THET) to define how many consecutive seconds this vertical speed has to be detected.

11 OPERATION CHECKLIST BEFORE A TASK
Be certain that the batteries are fully charged Download the waypoints from the competition organization web site Upload them on the Digifly Air with the software AirTools (PC) or GpsDump (PC e MAC), or copy them
transferring the file from one instrument to the other using the direct connection cable.
Edit a route accordingly to the task’s director instruction Insert correctly the turn points cylinders radius Insert correctly the start info (entering or leaving) Insert correctly the start hour If existing, insert also the ulterior gate time ( how may and when) In the route page verify that the total distance is corresponding (“Tot dst km”) Activate the route Set the barometric altimeter, it is top important because it used also by the glide’s computer. Before the takeoff, provide to turn on the instrument with the proper advance to acquire the proper GPS
position
After the GPS point acquisition, verify that the time is correct, in case correct the time zone (pay attention to
the summer time shift) otherwise the start time will be totally wrong.
12 NAVIGATION ROUTE
To have these info available it has to be activated a route’s navigation.
12.1 DIRECTION, DISTANCE & HEIGHT ON THE WAYPOINTS
This function indicates the direction, distance and the estimated arrival height above the current waypoint
(H1); the next Waypoint (H2) and the goal’s Waypoint (HA).
The arrival height above the current Waypoint (H1) is computed accordingly of the following info: Altimeter A1,
distance to Waypoint, Waypoint’s altitude and medium glide ratio.
The medium Glide Ratio is constantly updated during the glide and memorized during the thermal flight, to
change the GR media calculation time (in seconds) go to (ADVANCED SETUP \ n. 5 EFFA).
12.2 NEEDED GLIDE RATIO TO CURRENT WAYPOINT / NEXT WAYPOINT / GOAL
It is the estimated needed glide ratio to reach the current waypoint.
This info is available in all the three screens (Thermal, Glide Compass, and Glide Plotter) using the tools
“efr1”, “efr2”, “efrA”.
Page 31
12.3 OPTIMIZED NAVIGATION
The optimized navigation shows to the pilot the shortest way of the task’s route:
12.4 NAVIGATION TO START PYLON WAYPOINT
If the current waypoint is a Start Pylon, on the info bar appears the message “START PILON” and 3 minutes
before the start time it appears the message " 3 min to go! " emphasized by a beep.
3 minutes before of the start time some fields of the screen are automatically changed by the instrument
itself.
More: in the screen Glide Plotter, 3 minutes before the start time are changed also the first field from the top
showing the distance from the start “dst1” and the second one from the top where it is shown the tool “er0”,
that indicates in seconds the estimated arrival time to the start, based on the current medium speed referred
to the countdown. E.G: if this field shows “10” means that the pilot twill arrive at the start with a 10 second
late, if it shows “-15”, this means that he will arrive 15 second early (penalty).
Still in this condition, it is disabled the graphic indicator of the HSI.
When expires the time to the start (e.g. =00:00), it appears the message “Gate Opened” followed by a long
beep, advising the pilot that the start gate is opened and it is possible to cross the start line.
When the start time gate is open "Gate Opened" it is allowed to cross the start’s cylinder line (entering or
leaving accordingly of the selected IN / OUT option).
If the start’s pylon cylinder is crossed before the open start gate time, the start pylon distance’s indicator
blinks to show that the pilot is in the wrong side of the start pylon cylinder.
This instrument constantly drives the pilot toward the start line of the “start pylon” till t is properly crossed
from the right side, IF the start time gate is opened; if everything is correct it appears the message: "Start is
OK" and the navigator switches to the next waypoint.

12.5 NAVIGATION TO STANDARD WAYPOINT
If the current Waypoint is not set as a start pylon, the navigation is managed in ‘standard cylinder mode’ and
the Digifly Air will drive you providing constant
info about your posistion, distance, direction,
required glide ratio and expected arrival
height above the waypoint.
When you arrive near the cylinder (see the
Waypoint’s parameter NEAR) the flight
recorder rate is automatically set to one data
point per second. The parameter “NEAR” can
be modified from the page Waypoint’s edit.
Cylinder validation: entering in a cylinder the
Digifly air will alert you with a sound and will appear the messageo “WPOK”, then flight recorder rate returns
to the setup value (MAIN SETUP \ n. 5 RECR). .
12.6 NAVIGATION TO CONCENTRIC WAYPOINT
To properly manage a task’s route with concentric waypoints it is necessary to insert in the desired route the
same waypoint two-three or more times, accordingly to the task route, but with different cylinders radius.

13 FLIGHT RECORDER
When the Digifly Air starts the flight recorder, it compares the message “REC ON” and the icon “rec”
on the bottom of the display starts blinking. The following parameters are continuously
recorded: Date and time, Latitude, longitude, number of satellite, tracking GPS, ground speed GPS, altimeter
GPS, barometric altimeter A1, variometer and anemometer.
IMPORTANT: the flight recorder is automatically deactivated if the setup is modified or the flights are deleted.
13.1 ACTIVATING / DE-ACTIVATING FLIGHT RECORDER
The flight recorder can operate in three different ways:
- “AUT” Automatic flight recorder.
- “ALW” Flight recorder always active
- “OFF” Flight recorder de-activated.
13.1.1 AUTOMATIC START RECORD MODE “AUT”
By default setting, the flight recorder starts automatically, MAIN SETUP \n. 3 RECM = AUT The flight recorder activates automatically only if it is available the GPS position and it is detected a takeoff
with an altitude variation of at least 0,5m for 3 consecutive seconds. To change the altitude variation
parameter go to: (MAIN SETUP \ n. 4 R.DS = 0,5) the change the detection time parameter go to (MAIN
SETUP \ n. 4 R.TI = 3).
The flight recorder is automatically de-activated 60 second after the landing or if the instrument is turned off.
13.1.2 ALWAYS ACTIVE RECORD MODE “ALW”
To set the always active record mode parameter go to (MAIN SETUP \ n. 3 RECM = ALW). The flight recorder is
activated once the instrument is turned on and is de-activated when it is turned off.
13.1.3 RECORD MODE OFF “OFF”
To de-activate the flight recorder set the parameter (MAIN SETUP \ n. 3 RECM = OFF), no data are recorded.
13.2 RECORD RATE
The recorder rate can be adjusted from 1 to 60 seconds, go to (MAIN SETUP \ n. 5 RECR). setting 1 data point per second you can record over 10 hours of flight data. Setting 1 data point per minute, you can record up to 600 hours of flight data. The recorder memory has room for up to 45,000 GPS data point and up to 250 flights. When you are near a ‘GO TO’ Waypoint, the recorder rate is automatically increased to 1 data point per
second.
When the recorder’s memory is full, the oldest flight is automatically deleted by the new one. The remaining free memory time and percentage are shown for 2 seconds as the instrument is turned on If a single flight fills the whole memory, it is no more possible to use the recorder and the message “MEM
FULL” appears every time that you try to use it. To activate again the flight recorder it is necessary to clear the
