Operating Manual Flytec 6020 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.
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.
Operating Manual Flytec 6020 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.
Operating Manual Flytec 6020 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. key the volume level will increase each time by 25%. 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.
Operating Manual Flytec 6020 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.
Operating Manual Flytec 6020 Main Setup Menu ⇒ User Settings ⇒ Variometer ⇒ Basic filter . Filter type Depending on the condition, if the air is quiet or turbulent, one can select 5 different filters. See „Analog Vario“ page 14. The warning sound for Stall alarm is a pitch tone of medium height with a very fast interval rate and always at full volume level of 100%. All sound effects described here above may be heard in simulation mode. 2.

Settings. ⇒ Time zone 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.
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.

The 6020-GPS can save up to 200 different waypoints. Each waypoint can have up to 16 characters, e.g. “Fiesch Airfield”.
Operating Manual Flytec 6020 2.6.4.1 Waypoints - alter, delete or insert In this position of Setup-Menu the waypoints may be managed. Waypoints may also be set comfortably on the PC by use of the „Flychart 4.52“ PC-Software and be transferred via the PC-interface to the instrument. Waypoints Using Menu ⇒ Waypoints prompts a list with the waypoints -------------Flytec stored in memory.

The coordinates are also displayed when entering a waypoint using the key McC ⇒ F1 AddWp. 2.6.4.3 Memorising the actual Position It may happen from time to time that the current position should be saved as waypoint. For this purpose the key should be pressed during 3 seconds and subsequently the key ⇒ AddWp.
Operating Manual Flytec 6020 2.6.5 Flying Routes A route is an arrangement of various waypoints. The waypoints used on a Route need to be saved in the unit’s memory. Whilst in the Goto-Function the next WP has to be selected each time from a list by prolonged pressing of the key, when flying Routes it is possible to switch forward by briefly pressing the key ▲ (next WP) or ▼ (previous WP ) if one is inside the WP Menu. The WP Menu is enabled by prolonged pressing of the key.
Operating Manual Flytec 6020 Now at this point the individual waypoints need to be inserted into the Route. After pressing the key (lns.Wayp), the list of available waypoints will appear in the bottom half of the screen in alphabetical order. At the same time one will see the prompt: “Select Waypoint No1.” Again by using the ▲ or ▼ keys one has to search for the 1st WP and it is added to the Route by pressing the key. This is indicated in the upper half of the screen. By pressing the key (Ins.
Operating Manual Flytec 6020 This distance, or cylinder circumference can be set in Main Setup Menu ⇒ Routes ⇒ COMPETITION-ROUT for each waypoint separately within the range of 20 m up to max. 200 km. In Default- or factory settings a 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.
Operating Manual Flytec 6020 EXIT Cylinder WP2 WP3 WP1 Exit The signal „waypoint reached“ is audible as soon as the start time is reached and the pilot is inside the start cylinder. It will also sound if the start time is positive and the pilot crosses the start cylinder circumference from outside to inside. In both cases the next active waypoint will be enabled, in this case Waypoint2.
Operating Manual Flytec 6020 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.
Operating Manual Flytec 6020 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 WP1 WP2 Goal Start 2.6.6.
Operating Manual Flytec 6020 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.
Operating Manual Flytec 6020 CTR’s can be entered into the instrument either manually in Main Setup Menu ⇒ Airspace, or with less effort by assistance of a PC-program, e.g. Flychart, this program may be downloaded from our Internet Homepage at (www.flytec.ch). • • Without activation the user has 20 CTR’s at his disposal. One can in Basic Settings -> Init CTR’s call-up the CTR Innsbruck into the instrument and then alter it in Main Setup Menu -> restricted areas.
Operating Manual Flytec 6020 To enter arc segments, then the following sequence must be observed: Long, Lat centre; Long, Lat start point of arc segment; Long, Lat endpoint of arc segment; Rotational direction (+clockwise, - counter-clockwise) For circles the centre and the Radius are sufficient Long, Lat of centre; Radius in km. 2.7 Flight optimisation 2.7.1 Groundspeed (Speed over ground) The GPS-Receiver calculates its new position once every second.
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.
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.
Operating Manual Flytec 6020 Alt a BG 275m Best glide –exit point 931m over the goal L/D req 5.7 Best glide 8 act. height 956m 2km 681m Act. distance to goal 5.45 km 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.
Operating Manual Flytec 6020 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.
Operating Manual Flytec 6020 3 The Setting Menus OK Prolonged pressing of the key gives access to the setting mode. With the arrow keys▼ and ▲ one of the menu items is selected and pressing the key gives access to the relevant subdirectory. OK 3.1 User Settings A series of settings allow the instrument to be programmed in accordance to the user’s preferences. Every pilot may realise his very own ideas here.

Operating Manual Flytec 6020 3.4 Specific Instrument factory settings This default value, which is not accessible to the pilot, contains all basic settings of the instrument. In particular, both the sensor specific parameters and all calibration data are located here. These data are not lost, even when the power supply is missing. 4 Flight Memory and data analysis The flights are recorded inside a Flash-Memory (see below).
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.
Operating Manual Flytec 6020 4.1.1 Logbook and Flight Analysis page After leaving the Flight-Analysis the flight is saved in the flight memory. Data and Track of the flight can be viewed on the Flight-Analysis page. Under Main Setup Menu ⇒ Flightmemory appears the list of saved flights in chronological order. The recent flights rank first. The duration of the flight is also displayed.
Operating Manual Flytec 6020 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.
Operating Manual Flytec 6020 4.3.1 Fightinstrument Option All settings can be set or changed comfortably with Flychart 4.52 User settings and Instrument settings Waypoints Airspace 4.3.2 Waypoints and Routes Within the same Flychart Menu the Waypoints and Routes may be transferred to the instrument. Flychart is also appropriate to import waypoint files from SeeYou or CompeGPS or Garmin for transfer to the instrument. 4.3.3 Airspace (CTR) The same principle applies on Airspace.
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.
Operating Manual Flytec 6020 6 Simulation OK After choosing the Simulation mode in the Setup Menu and pressing the key, you have access to this highly interesting function. With the arrow keys and you shift the Simulation checkbox to “Yes” and confirm again with . Now the simulation starts and the last known GPS position is applied. With the ► and ◄ arrow keys you can adjust the speed through the air and ground speed; the ▲and ▼ arrow keys change the sink or the climb.
Operating Manual Flytec 6020 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.
Operating Manual Flytec 6020 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.
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.
Operating Manual Flytec 6020 an altitude limit to be adjusted by the pilot in Main Setup Menu ⇒ User Settings ⇒Speed ⇒Stallspeed above which the stall alarm shall not be initiated. In this case naturally, the landing areas should be located below this limit. Practice has proven that about half of the otherwise unattractive landings have been rescued by pushing the steering bar upright when the stall alarm was triggered. 9.3 Navigation 9.3.
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.
Operating Manual Flytec 6020 Satellite 2 Almost no time difference Satellite 2 Satellite 1 Time difference Satellit 1 Position A Position B 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.
Operating Manual Flytec 6020 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.
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.
Operating Manual Flytec 6020 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.
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“.
