Operating Instructions FLYTEC 4020 3 General remarks Introduction Flytec’s 4020 is a completely new development. The new instrument is now more compact, lighter and more economical thanks to the use of the very latest technology. The 4020 is an instrument which you can adjust to suit your requirements. For this reason, all important data can be altered quickly and easily.

This is why each key has only one function, i.e. a function can be displayed and switched on or off with each key.
Operating Instructions FLYTEC 4020 6 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 INDICATOR display. The value to be changed begins to flash. ALT 1 ALT 2 CHRONO In order to return to run mode, press the relevant function key briefly (e.g.
Operating Instructions FLYTEC 4020 7 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.
Operating Instructions FLYTEC 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 represents 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.
Operating Instructions FLYTEC 4020 9 Altimeter 1 option mode In option mode, you can set the unit for ALT 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).
Operating Instructions FLYTEC 4020 10 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.
Operating Instructions FLYTEC 4020 11 Vario Vario sound levels Two sound levels can be set or the sound system switched off completely by repeatedly pressing the key. While the key is pressed, a tone will sound at the desired level. 0-I-II 0-I-II 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.
Operating Instructions FLYTEC 4020 12 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.
Operating Instructions FLYTEC 4020 13 Descent tone/Descent alarm The descent tone is a continuous tone dependent on descent which sounds as soon as descent is greater than the response point. The descent tone can be set or switched off with the key. When the descent tone is active, the SINK indicator is displayed. When the descent tone is first switched on, a mark appears in the bar display indicating the response point set.
Operating Instructions FLYTEC 4020 14 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 probes have an accuracy of approximately + 2.
Operating Instructions FLYTEC 4020 15 Option mode of the speedometer SPEED 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. SPEED 4 Sec. SPEED At the second level, the desired unit of the speed display is set. You can choose between kilometers per hour (kph), miles per hour (mph) and knots (kts) by using the key and the key.
Operating Instructions FLYTEC 4020 16 Time measurement and temperature display Clock time (real-time clock) TIME SPEED In the lower display, the key is used to toggle between speed, time and MEMO display. The time, the date and the year can be set in setting mode. MEMO Stopwatch (CHRONO) The stopwatch is displayed in the upper display. It can be started and stopped with the key. If the stopwatch has been started, the indicator CHRONO will flash.
Operating Instructions FLYTEC 4020 17 Time measurement and temperature display setting mode CLEAR ALT 2 The key and the key are used in setting mode to set the time. The hours and minutes are set first and confirmed with the key. The date can now be entered in precisely the same way. This input is again confirmed with the key. The year is also entered and confirmed in the same way. START - STOP RESET TIME/TEMP TIME SPEED MEMO TIME 4 Sec.
Operating Instructions FLYTEC 4020 18 Logbook General remarks The maximum values of the current flight and those of the previous 19 flights are saved in memory and can be invoked in the MEMO display and printed out on a printer. You can access the MEMO display by repeatedly pressing the key until the MEMO indicator appears.

Operating Instructions FLYTEC 4020 Barograph setting mode 20 MEMO In setting mode, all flights in the logbook can be deleted and the recording interval of the barograph can be set. In setting mode, the recording interval saved is displayed first. Using the key or the key, change in the MEMO display between the recording intervals 1, 5, 15 sec and CI. Briefly press MEMO to save the interval displayed and thus leave setting mode. MEMO 4 Sec.
Operating Instructions FLYTEC 4020 21 At the fourth level, you can enter your name; the name entered appears on the logbook printout. The individual letters of the name must be entered individually as ASCII code ( ASCII table in the appendix). The letter displayed is confirmed with the key and the next displayed. The name may be 21 characters long. The number of the character appears in the digital vario display and the ASCII code for the character is shown in the MEMO display.
Operating Instructions FLYTEC 4020 3. 22 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.
