Keyboard

Operating philosophy

The philosophy behind all Flytec instruments is to keep everything as simple as possible. This is why each key has only one function, i.e. a function can be displayed and switched on or off with each key. In or der to alter a function, you pr ess and hold down the r elevant function key. The setting to be changed will then flash and can be altered by pressing and .

The instrument has three operating modes: normal operating mode, setting mode and configuration mode.

Run mode (normal operating mode)

The instrument is in run mode when used in normal operation. In run mode, the instrument will display your altitude, ascent and the time continuously.

Setting mode (for adjustments)

In setting mode, the most important value can be changed for each display. For example, the altitude can be set by using the setting mode for altimeter 1.

Enter setting mode for a particular display (e.g. for altimeter 1), by pressing the relevant function key (e.g. ) and holding it down for about 4 seconds. As soon as you are in setting mode, the SET indicator will appear in the INDICA TOR display. The value to be changed begins to flash.

In order to return to run mode, press the relevant function key briefly (e.g. ) If no change is made in setting mode for 15 seconds, the instrument returns to run mode.

Option mode (configuration mode)

Option mode allows you to configure the instrument to your requirements and prefer ences. In option mode, you can set the parameters for the relevant display or function at various levels. For example, these can be units or special functions. A precise description of the various settings in option mode is given in the descriptions of the individual functions.

You can enter option mode (in the setting mode of a function) by simultaneously pressing the two keys marked “Option” in yellow (Fig. 1). If the instrument is in option mode, this is confirmed by the OPTION indicator in the INDICA TOR display.

In OPTION mode you can change several parameters. By briefly pressing the relevant function key (e.g. ) you skip from one level to the next. In each level you can change one parameter of the relevant function. The level number will appear each time in the digital vario display.

If no change is made for 15 seconds in option mode, the instrument returns to run mode.

In order to return to run mode manually , pr ess the two option keys simultaneously again (Fig. 1).

Using FlyChart 4.0 software on a PC, all settings in setting and option modes can be conveniently set and transmitted to the instrument via the PC interface.

Commissioning

Switch on the instrument with the On/Off switch. On being switched on, the instrument goes through a self-test routine and then enters run mode.

When switched on, the instrument settings correspond to those valid when the instrument was last switched off.

When first switched on, the instrument displays the approximate charging status of the batteries in the vario bar display. If the display shows approximately 50% of the maximum display in the green sector, the batteries are still half full. If the display is in the red sector, the batteries must be changed. If the batteries are low on charge during a flight, PO will light up briefly in the digital vario display and, at the same time, the charging status of the batteries is shown in the bar display.

The battery life of the instrument using alkaline batteries is 160 hours. Rechargeable batteries can also be used. However, operating time is substantially shorter with these (total operating time is approximately 40 - 50 hours).

Alkaline batteries can also be recharged several times using the appropriate char ging unit (no fast chargers!).

The altimeter

General remarks

How does an altimeter work?

An altimeter is really a barometer because it does not measure altitude directly but pressure. The altitude is then calculated from the pressure. For the purpose of calculating absolute altitude (according to the international formula for altitude), the pressure at sea-level is assumed as being zero-point pressure.

Why does pressure change with altitude? The air pressure at a point on Earth is pr oduced by the weight of the atmospheric air above it. This is why air pressure decreases with altitude there is less air above your head! At 500 meters above sea-level, a pressure change of 1 mbar corresponds to a difference in altitude of about 8 meters.

In practice, however, it is not quite that simple as other factors also have an influence on air pressure. Pressure also depends on temperature and, of course, weather. On a stable day, there can be air pressure fluctuations of 1 mbar caused by temperatures and this corr esponds to a difference in altitude of ± 10 meters. Depending on the weather, air pressure at sea-level (QNH) can be between 950 mbar and 1050 mbar . In order to eliminate this weather effect, an altimeter needs continual recalibration. This means that the altimeter must be set at a known altitude to display that same altitude.

Operating Instructions FL YTEC 4020 8

When the weather changes fast (e.g. cold fronts), air pressure can change in the course of a day by up to 5 mbar . This r epresents a change in altitude of 40 meters!

Another method of calibrating an altimeter is by entering the current QNH. What is the QNH? In flying circles, a general zero point is needed to enable all aircraft at the same altitude to also have the same altitude on their altimeters. This joint basis is called the QNH. The QNH is the current air pressure in hPa (1 hPa = 1 mbar) calculated at sea-level. It is redetermined several times daily and can be obtained in the flying weather report or from airfields by radio.

Altimeter 1 (ALT 1)

Altimeter 1 displays absolute altitude, i.e. the altitude above sea-level. Function key is used to change from the displays for altimeter 1, altimeter 2 and the

stopwatch. Pressing and holding down this key will make the instrument go into setting mode. Attention: While a flight is being r ecorded (REC

activated) the setting mode is blocked for Altitude 1. This altitude can only be readjusted after the REC has been switched off. This is an FAI requirement.

Altimeter 1 setting mode

As mentioned above, the absolute altitude can be setin setting mode. The altitude and the

QNH flash on 2 lines. Using the setting keys and , you can set the altitude and the QNH simultaneously. If you do not know what altitude you are currently at, you can set the altitude using the QNH but this method is not as precise as direct altitude setting. The QNH has a resolution of 1 mbar which corresponds to an altitude resolution of approximately 8 meters. The altitude, however , can be set dir ectly to an accuracy of 1 meter .

Pressing the setting keys and simultaneously will take you from setting mode to option mode.

Altimeter 1 option mode

In option mode, you can set the unit for AL T 1 (meters or feet) at the first level and, at the second level, you can set the unit for the QNH (hPa or inHg). The indicator for the relevant unit set flashes in the display. The pressure sensor can be corrected at the third level (±50 hPa). If you find that the QNH value displayed at a known altitude deviates seriously from the QNH value of a weather station in your area, you can correct this deviation by entering the deviation (with a different prefix). I.e. if the QNH displayed by your instrument is 20 hPa too high, enter

-20 to correct this deviation. This deviation is caused by the aging of the pressure sensor and stabilizes after 2 - 3 years. N. B.: Incorrect manipulation of the correction value of the pressure sensor will result in false

altitude readings! Never alter the basic settings of the altimeter unless you have good reason to do so (in your own interest)!

In option mode, the indicators OPTION and AL T 1 appear and the relevant number of the module is shown at the top of the display. The unit to be adjusted will flash.

Altimeter 2 (ALT 2)

Altimeter 2 can either be used as an absolute altimeter or as a relative altimeter.

When used as an absolute altimeter , it functions in precisely the same way as altimeter 1. Altimeter 2 can now, for example, display the altitude in feet and altimeter 1 the altitude in meters.

The relative altimeter displays the current altitude with reference to a point. This reference point can be set at zero in run mode at any time by using the key or set at any altitude in setting mode. The relative altimeter can thus be used to measure the higher altitude of the takeoff area. Pressing the key at the take-off area will zero ALT 2 for this purpose.

Altimeter 2 setting mode

The altitude can be set in setting mode in precisely the same way as with altimeter 1. If altimeter 2 is selected as the absolute altimeter, it is coupled to altimeter 1. Any change in

the display for altimeter 1 is reflected by a corresponding change in the display for altimeter 2 and vice-versa.

Altimeter 2 option mode

In option mode, you can select the unit (meters or feet) at the first level as with altimeter 1. The unit selected flashes in the display. You can toggle between units by pr essing either the key or the key.

Press key to enter the second level of option mode. At this level, you select the opera- ting mode of altimeter 2. If this is set at absolute altimete, the two indicators AL T 1 and ALT 2 will flash in the display. If set at r elative altimeter, only the indicator ALT 2 will flash.

You return from option mode to run mode by waiting 15 seconds or again pressing the two keys marked “OPTION” simultaneously.

Vario

Vario sound levels

T wo sound levels can be set or the sound system switched off completely by r epeatedly pressing the key. While the key is pr essed, a tone will sound at the desir ed level.

Analog vario bar display

The vario bar display has a range of ± 8 m/s in two scale passes. The scale unit always corresponds to 0.2 m/s. Up to 4 m/s , the bar display fills. If it displays more than 4 m/s (ascent), the ascent is displayed inverted, i.e. the display is full at 4 m/s and empties from below when ascent increases.

E.g.:

The sensitivity of the bar display corresponds to the basic attenuation of the vario (‡ setting mode of the vario). It therefore always displays current ascent.

Digital vario display (Integrator)

The digital vario displays the attenuated climb rate for the last X seconds in second rate. The time X, via which ascent is attenuated (integration time), can be changed at the first level of option mode. These values appear flashing in the digital vario display.

Y ou can enter the vario’s setting mode by pressing the key for a long time (appr oximately 4 seconds).

Vario setting mode

The basic attenuation of the vario can be altered in setting mode. The basic attenuation of the vario is effective on all vario functions; it can be set to 0.5 sec, 1 sec or 1.5 sec.

N.B.: The fastest vario is not always the best vario. In very rough and severe conditions, it is advisable to attenuate the vario more. Turbulences are then filtered out by the attenuation and not displayed.

You can enter option mode by simultaneously pressing the two option keys.

Vario option mode

The integration time of the digital vario can be altered at the first level of option mode. The values are in 5-second steps between 5 and 35 seconds and appear flashing in the digital vario display. At setting 1, the digital vario is displayed without averaging and then runs parallel to the bar display. The values can be altered with the and the keys.

The audio response point can be adjusted at the second level. The audio response point can be adjusted from +2 cm/s to +40 cm/s. The current response point appears in the bar display and represents one tenth of the value displayed. E.g.: a display of 2 m/s corresponds to an audio response point of 20 cm/s.

The digital vario unit can be selected at the third level: m/s or feet/min x 100. The current setting flashes in the digital vario display. You can switch between the two units with the key.

Speedometer

General remarks

A speed sensor (speedometer) can be purchased as an accessory. The speed sensors in the 3000 series can also be used with instruments in the 4000 series.

The accuracy of a vane wheel sensor is highly dependent on its point of attachment. Additionally, the individual pr obes have an accuracy of approximately + 2.5% (industrial stan-

dard) resulting from manufacturing operations and it is possible for two probes not to display exactly the same speed. These deviations can be largely corrected by the instrument. (±option mode of the speedometer).

Display

If a vane wheel sensor is connected to your instrument, speed (in kph, mph or knots) relative to the air can be shown in the lower display by pressing the key .

When a stall alarm is switched on, a warning tone sounds when speed falls below a certain absolute speed. No stall alarm will sound at speeds that are below 10 kph. If the threshold is set at 10 kph (or 5 mph), the stall alarm is switched off.

The current time can be shown every 30 sec in the SPEED display ( option mode of the speedometer).

Correction

If a probe always displays too much or too little, this deviation can be corrected at the third level of option mode.

Speedometer setting mode

The response threshold of the stall alarm can be altered. If the threshold is set at 10 kph (or 5 mph), the stall alarm is switched off.

TIME SPEED

MEMO

Option mode of the speedometer

At the first level, you have a choice of whether the time should be displayed automatically every 30 seconds when the speed display is switched on.

At the second level, the desired unit of the speed displayis set. Y ou can choose between kilometers per hour (kph), miles per hour (mph) and knots (kts) by using the key and the key.

At the third level, you can also make adjustments to the correction of the speedometer. The correction value is given in percent using the key and the key. If the speed display is uncorrected, the display will show 100 (%). If the display still shows a 4% excessively high value (e.g. 50 kph instead of 48 kph), the display is corrected by setting 96 (%). This means that the display will now always show 96% of the original speed.

3. The observer must switch the instrument on and check that the time, the date and the

take-off altitude have been set correctly. If any of these values are incorrect, the observer must set them to the correct value ( setting mode altimeter 1.) The time has to be corrected in the time mesurement display setting mode.

ATTENTION:The real time clock and the date can no longer be altered once the barograph recording has been activated with the REC switch. These two functions can only be reset when the memory has been cleared ( setting mode of the barograph).

4. The observer must switch the barograph on (REC).

5. The observer must continuously observe the pilot until take-off and verify that the pilot

takes off with the instrument. The observer must note the exact time of take-off using an independent timepiece.

6. After landing, the pilot must set the REC switch and then the instrument to Off.

7. Printout: The observer must verify that the instrument displays the correct time and date

and note any discrepancies with respect to local time. The observer must verify that the
