To view the track of a saved flight, press F1 (Shw Map) while viewing the Flight Analysis page

(see Section 8, “Flight Memory and Flight Analysis”). This display shows your screen-optimized

flight track with scale and waypoints (North is located at the top). You can change the display

using the F1, F2, Enter and Esc keys; all other keys cause the track in the current selection to be

redrawn.

F1 (Zom Out): The map scale is gradually decreased until the screen display is optimized.

F2 (Zom In): The map scale is gradually increased. At maximum zoom individual thermaling

circles will be clearly recognizable, provided a short record interval was selected.

Enter:Reverts the display back to the screen optimized track.

Esc:Back to the Main Setup Menu.

Arrow keys: Use these keys to shift (pan) the plotted area up, down, left and right. This function

is only enabled in Flight Memory mode. During flight, your actual position is in the center of the

map. If your position reaches a border, the map pans automatically.

Note: Depending on the amount of data in the track, it may take a few moments for it to appear.

The status line will show “Wait” or “Ready” accordingly. If you press a zoom or pan key during

the process, the redraw will re-start with new values. This way you will be able to quickly obtain

the desired zoom or section of the track.

1.1 Final Approach Screen

The final approach screen is primarily used on final glide but also may be useful when

approaching turnpoints. The horizontal axis shows the deviation between your current track and

the bearing to goal (or the next turnpoint). The vertical axis shows the deviation between the

necessary glide ratio to goal (or next waypoint) and the best glide of your glider as set in the

Basic Settings. If the glider symbol is below the horizontal axis the target cannot be achieved

without gaining additional altitude. If the glider symbol is on the horizontal axis the target should

just be in reach by flying best glide speed. During thermaling the glider symbol remains centered

on the vertical axis. When your glide ratio has decreased to within 6 points of your best glide the

symbol will be shown at the bottom of the vertical axis. As you climb higher the glider symbol will

move accordingly up the vertical axis.

At the top of the approach display there are 3 small arrows (< ^ >), one of which will appear

when you are on glide (not climbing) to provide heading assistance. If the deviation between

your track and the bearing to goal exceeds 60°, the glider symbol will be grayed. In this case,

switch to the Vario Screen by using Esc to see the compass with the direction markers.

1.1 Battery Management

The 5020 has 2 bar scales that indicate the remaining capacity of the batteries. There are 2

banks of 2 AA batteries each. Battery Bank 2 may be empty but Bank 1 must always be

equipped; however it is recommended that bank 2 be equipped as well. As soon as the first bank

is depleted, the instrument will automatically switch to the second bank. If the second bank is not

yet completely used up, and Bank 1 is equipped with new batteries, the instrument switches to

the first bank again. After a long flight it is recommended that the partly used batteries of Bank 2

be moved into Bank 1, and Bank 2 be equipped with new batteries. This will allow the 5020 to

completely use up the batteries without the danger of having empty batteries during a flight.

The following battery types are recommended:

• Alkaline AA 1.5V (e.g., Energizer or Duracell) - Estimated operating time 20 hours per bank.

• NiMH AA 1.2V 2100mAh - Estimated operating time 16 hours per bank.

• NiCd batteries may also be used but they have smaller capacities and shorter operating time.

The inserted battery type is not automatically detected by the 5020. Because the various battery

types have different voltages and different temperature behaviour, you must select the battery

type in Main Setup Menu/Basic Settings/Battery Type. The estimated battery life is based on

normal temperature conditions; hotter or cooler operating temperatures will affect battery life.

Please recycle spent batteries

1.1 Data Exchange via PC

The 5020 comes complete with a serial PC interface data cable (9 pol Sub D plug). See section

10.7, “Data Exchange via PC” for information.

The following can be read via this RS232 interface:

• Serial numbers and pilot names

• Waypoint list

• Route list

• A selected flight track log

The following can be uploaded to the 5020:

• Waypoints

• Routes

• Instrument configuration

Bank 1

Bank 2

Bank 1

Bank 2

Important: the 5020 must first be switched on before plugging in the connection cable to the

unit and the computer.

WARNING: In very rare cases it can happen that a flight instrument does not provide any

data at all or the data is incorrect. Flytec will not be held responsible for accepting any

damage claims arising from a malfunctioning unit. Responsibility for ensuring the safe

execution of his/her flights lies with the pilot alone.

1.1 Transferring New Firmware to the 5020

As is the case with many other new products, particularly during the introduction phase,

improvements or feature enhancements may be expected. Periodically Flytec will post firmware

updates at www.flytec.ch and www.flytec.com for you to download free of charge and upload to

your 5020. To be able to write to your 5020’s flash memory with a PC, you will need to use an

upload utility program named “Flasher.exe,” available from Flytec’s website in zipped form

(flasher.zip). Then you will need to download the actual firmware; it will be called “5020v*.**.moc”

where *.** corresponds to the firmware version number (e.g., 1.13).

1 Warranty and Liability

Our instruments carry a 24-month warranty. However, physical damage such as a broken

housing or display window as well as damage resulting from water landings are excluded from

this warranty. Flytec AG can accept no liability for faults arising from any abuse or unapproved

use of your instrument.

Important: Contrary to the instructions for data transfer of waypoints or routes, be sure that

the 5020 is turned off when plugging the cable into the computer and the 5020.

Important: Never leave the PC cable hooked up to the unit when it is turned off. This will

consume energy and can drain the battery.

2 Analog Vario

The most important instrument function for any kind of glider flying is the vario. The 5020

displays vertical speed in fpm or m/sec and tells you whether you are climbing or sinking. The

resolution of the analog vario (dial display) is 40 fpm or 0.2 m/s. The first full-scale range is from

+/- 0 to 800 fpm (+/- 4 m/s) after which the display switches automatically to a second range

from 800 to 1600 fpm (4 to 8 m/s). The time interval (damping) over which the measured climb

rates are averaged for the analog vario (and associated sounds) is factory set at 1.2 seconds.

This can be changed to any value between 0.6 sec and 4 sec. in Main Setup Menu/Basic

Settings/Vario/Spd Delay. If the time interval is too short, the vario is very twitchy; if too long, it’s

rather sluggish. A lower dampening value is preferable for smooth light conditions. A greater

dampening value may be desirable in rough turbulent conditions. Note: This setting should not

be confused with vario integration (averager) that can be set for the digital vario display (see

Section 5.3, “Digital Vario”). Additionally, in the Vario/Spd Delay menu a small pre-filter (i.e.,

turbulence filter) can be adjusted with a range of 0.1 second to 1 second (settings 1 to 10).

2.1 Altimeter and Air Pressure

The 5020 tracks and can display 4 different altitudes and the QNH. A1 is shown on the right side

of the vario screen and A1, A2, A3, FL and QNH can be displayed in the user-selectable fields.

A1 Altitude above sea level (QNH).

A2 Altitude with respect to a reference height that can be altered or zeroed at any time.

Press F1 (Nxt Fnc) until “Mod A2

↑↓

“ appears, then use the arrow keys to change

A2. Press F2 to reset A2 to zero.

A3 The total height gained during a flight.

FL (ft) Flight-Level is based on an air pressure of 29.92 inHg (1013 hPa) at mean sea level. It

cannot be adjusted by the user.

You should adjust A1 to display your actual height above sea level (QNH) before starting each

flight. The QNH is originally set at the factory to a sea level pressure 1013hPa. Since it is

unlikely that you are taking off from sea level and the air pressure is also 1013hPa, the correct

altitude should be set. When you first switch on the 5020 the display will show “Mod Alt1

↑↓

.”

Use the  arrow keys to set the desired altitude. If you have accessed other screens or

functions prior to setting the altitude, press F1 (Nxt Fnc) to bring up “Mod Alt1

↑↓

.” Note: Once

the flight has begun Alt1 can no longer be adjusted and “Mod Alt1

↑↓

” cannot be brought up with

F1.

If the altitude of a launch place is unknown you can set Alt1 to the GPS-derived altitude

(assuming the GPS has reception) by pressing F2 (QNH GPS). If there is no satellite reception

the 29.92InHg (1013 hPa) altitude will be used (same as FL (ft)).

If you set Alt1 to zero while you are in a planned landing area, then your height above this

location will always be displayed in Alt1. The associated air pressure (QFE) will be the actual air

pressure in hPa at this spot, which deviates from QNH, the pressure at sea level, according to

the difference in altitude.

Flytec 5020 Technical Manual

2.2 Acoustics and Volume Level

Each time you briefly press 0-I-II, the volume level increases by 25%. The adjustable sound

levels are: 0 - 25% - 50% - 75% - 100%. Each time you press 0-I-II, the chosen volume level

will briefly appear in the display. All of the sound effects described in this section can be heard in

simulation mode (see Section 10.1, “Simulation”). To adjust sounds go to Main Setup

Menu/Basic Settings.

Automatic volume control: If volume is set to 25%, 50%, or 75% it will automatically increase as

your airspeed increases. There will be no increase of the 100% setting since it is already at

maximum volume.

Vario audio threshold: The ascent tone starts when your climb rate exceeds a predetermined

threshold. To set the ascent tone threshold (the lift value that must be exceeded to start the

ascent tone) go to Main Setup Menu/Basic Settings/Audio Threshold. The greater the threshold

value the greater the lift needed to initiate the ascent tone.

Vario beep frequency: The frequency (Hz) of the acoustic vario increases as you encounter

increasing lift. The starting frequency can be set between 600 Hz and 1400 Hz in Main Setup

Menu/Basic Settings/Variotone/asc.F.

Modulation: The rate at which the frequency of the ascent tone increases as you encounter

increased lift is called modulation. The modulation of the ascent audio can be adjusted to values

from 2 to 9 under Main Setup Menu/Basic Settings/Variotone/mod. The higher the value, the

faster the frequency will increase as the lift values increase. A modulation setting of 9 will yield

more audible change at lower climb rates making it best suited for use in mild lift.

Sink Tone Frequency: The Frequency (Hz) of the descent audio decreases as you encounter

increasing sink. The starting frequency can be set between 600 Hz and 1400 Hz in Main Setup

Menu/Basic Settings/Variotone/asc.F.

Dampening: The vario value is re-calculated every 0.2s. Rapid changes in vertical speed

(turbulent air) may result in wide variations in the frequency of the vario audio (piano effect). To

Flytec 5020 Technical Manual

- 14 - © Flytec USA

reduce this, you may add damping to make the vario audio more settled. Set the amount of vario

audio dampening in Main Setup Menu/Basic Settings/Variotone/damp.

Pitch: By altering the pitch value (between 1 and 7) you can customize the beep/pause interval.

A pitch setting of 1 will yield a longer beep with a longer pause between beeps while a setting of

7 will yield a shorter beep with a shorter pause between beeps. The pitch value is set under

Main Setup Menu/Basic Settings/Vario tone/pitch.

Sink Tone Threshold:The threshold, or the sink value at which the sink tone starts, can be set

between -10 and -2000 ft/min (–0.1 and –9.9 m/sec) in Main Setup Menu/Basic

Settings/Sinktone Thres. The sink tone threshold can also be set with F1 (Nxt Fnc). Repeatedly

press F1 until “S. Thr –*.*” is shown in the Information Lines and use the arrow keys to

change the value to the desired setting. You can also toggle the sink tone off/on with F2.

Note: A low quiet random noise may be heard even if the speaker is set to 0%; this is a normal

effect of operation.

2.3 Digital Vario

The digital vario has a resolution of 20 ft/m (10 cm/s) and a very wide measuring range of

+/14,000 ft/min (+/-70 m/s). The digital vario can be set to function as an averager (also called

integrated vario), with an average period between 1 and 30 seconds. This is very useful in

determining the actual strength of a rough thermal.

3 Airspeed

The 5020 has an input for a vane wheel speed sensor. It shows the true air speed (TAS) and

begins to make correct measurements above 1 mph (1 km/h). The vane wheel sensor is also

well suited for determining the wind strength at take-off. In Main Setup Menu/Basic Settings/Spd

Corr./Vane you can calibrate the displayed speed from 70% to 150% (default is 100%).

Many paraglider pilots fly without a speed sensor. In this case we recommend displaying only

the GPS-Speed (ground speed). Firmware versions 1.12 and later provide mathematically

derived air speed when flying without the vane sensor. This value is found by a vector addition of

ground speed and the wind velocity. To get the wind strength and direction, you must fly a full

circle at regular intervals; the calculated airspeed will be available at that time.

3.1 Stall Alarm

The warning tone for stall alarm is a midrange tone with a fast interval and full volume. The

threshold speed and altitude for the stall alarm can be set under Main Setup Menu/Basic

Settings/Stallspeed. To turn off the stall alarm set the threshold speed to 0.

4 GPS Functions

The use of GPS receivers has become indispensable for navigation. A network of satellites circle

the Earth and it is possible to determine your position very precisely anywhere in the world by

simultaneously receiving signals from several of these satellites at the same time.

4.1 Assessment of Reception Quality

The 5020 integrated GPS Receiver can track up to 16 satellites at the same time. After the unit

is turned on it must receive at least 4 satellites to fix its initial position. Once acquired, only 3

satellites are necessary for further navigation (for 2D positioning). However, if you want to record

altitude in a flight record (3D positioning) then 4 satellites are required. For competition flights it

is necessary to have 3D positioning.

There is a satellite almanac table in the GPS receiver that keeps track of the path, place, and

time of all satellites 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

5020 is taken more than 125 miles from the last reception point, then the almanac has to be re-

established. In this case it can take ten minutes (or more) to determine the new position. When

the 5020 is turned off, power is still supplied to the almanac’s memory. The instrument will loose

the almanac if the batteries are removed from both battery banks.

If the receiver is turned off for only a short period of time (less than 2 hours), it should take less

than a minute to acquire satellites. Buildings, mountains or thick forest affect reception quality.

Therefore, when you first turn on the 5020 for the day, you should place the 5020 with the best

possible view of the sky, and place the antenna (under the 5020 label) pointing upwards. For the

same reason, when you attach the 5020 it should not have more than 45° deviation from a

horizontal position. Because the receiving strength of the satellite signal is only 1/1000 of mobile

radios, these radio receivers and other disruptive devices (like notebook computers) should be

kept as far away as possible from the Flytec 5020.

The arrowhead bar scale in the top right corner of the vario page shows the number of satellites

being received. Each filled-in arrow represents one satellite with good reception. The greater the

number of filled in arrowheads, the better the overall GPS reception.

Flytec 5020 Technical Manual

4.2 Compass and Flight Direction

Unlike a normal magnetic compass, which is oriented to magnetic north, the GPS compass can

show direction only when you are moving. However, it has the advantage that it is not subject to

any grid deviation and does not show any deviation as a result of proximity to iron or magnetic

material. Its zero point always corresponds with true geographic north (0° or 360°).

The flight direction (track) is calculated by the GPS from your movements. If you remain

stationary then the course and compass needles are inoperative. The exact course (that is, the

direction in which you travel over ground) is always at the top of the compass, but can also be

read in the user-selectable Track field. When circling in a thermal the compass rose appears to

turn; in reality the needle does not move, the 5020 moves around the rose along with the aircraft.

4.3 Track and Bearing

As is the convention with GPS

receivers, the track is defined as the

route of the aircraft over ground.

Geographic true north is always 0° or

360° (east is 90°, south 180°, west

270°). Bearing is the direction to a

specific destination or waypoint from

the aircraft, expressed in the same

way. It can be displayed in a user field.

Note: A Tracklog is the result of

recording many different position

points during a flight.

4.4 Speed Over Ground

The GPS receiver fixes its position

once every second. Speed over the

ground is derived from the distance

and time between these positions. By

comparing the difference between

airspeed and groundspeed

conclusions about the wind’s influence

can be derived. Ground speed (Gnd Spd) may be displayed as a user field.

4.5 Glide Ratio (L/D Ratio)

By definition, the glide ratio is calculated by taking the horizontal distance traveled and dividing it

by the altitude lost. The following different types of glide ratio can be selected as a user fields:

Glide ratio through the air:

L/D air = TAS/Sink (True airspeed divided by sink)

Glide ratio over the ground:

L/D gnd = GS/Sink (Ground speed divided by sink)

Required glide ratio to destination:

L/D req = Distance to the waypoint divided by the altitude difference to the waypoint.

Flytec 5020 Technical Manual

4.6 Head, Cross and Tail Winds — the Wind Component

During an XC flight or when calculating a final glide, the wind component (i.e. the difference

between ground speed and air speed) is very important. In most cases the wind does not blow

directly from the front or from behind. If the wind component, Spd-Diff in the user fields, is

positive, then you are flying with a tail wind and your glide ratio over the ground will improve. If it

is negative then you are flying with a head wind and your glide ratio will worsen. The Flytec 5020

takes the wind into consideration when calculating final glide. To learn how to find the correct

angle between your destination and the wind when a strong cross wind is present, please refer

to Section 7.9, “The Goto Function.”

4.7 Wind Direction and Speed

It is very important to know the wind direction and speed

when flying XC and before an out landing. The wind speed

(Wind Spd) can be selected as a user field. It is necessary

to fly one or two complete circles as steadily as possible in

order for the 5020 to determine the wind direction and

speed.

The instrument calculates the wind from the difference

between Airspeed and Groundspeed. Wind direction is

shown in the compass rose by a small windsock. During

the final landing approach, this symbol should always be

at the top of the compass rose (to the extent the landing

field will allow). Note: If the windsock covers one of the

compass cardinal directions (N, E, S, or W) the letter will

disappear.

4.8 Waypoints and Coordinates

A waypoint is any single point on the earth’s surface that you would like to go to. The Flytec

5020 can save up to 200 different waypoints. Each waypoint can have up to 16 characters, e.g.

“Quest Air.” To navigate to a waypoint you also need its coordinates. If you desire final glide

information the altitude of the waypoint must also be entered in the waypoint’s altitude field.

For entering coordinates the Flytec 5020 utilizes the most international and commonly used

geographical grid: WGS84 (World Geodetic System 1984). This reference system assumes that

latitude is measured from the equator (0º) to the North Pole (90º North) and to the South Pole

(90º South). Longitude is measured from the Greenwich meridian in London (0º). East is positive

(up to 180º). West is negative (up to -180º). UTM and Swiss Grid are also possible.

The Flytec 5020 can also interpret waypoints entered according to the convention of using 3

letters and 3 numbers. Example: LAB167 indicates a waypoint with the name LAB*** at an

altitude of 1670 meters MSL.

The following position formats can be set in Main Setup Menu/Basic Settings/Coordinate Format.

1) Degrees Decimal Minutes dd°mm.mmm

2) Degrees Minutes Seconds dd°mm’ss”

3) Decimal Degrees dd.ddddd

4) UTM

5) Swiss Grid

Wind direction

Flytec 5020 Technical Manual

Whenever possible the format dd°mm.mmm should be used because this format is the same

that GPS receivers use and will provide the highest degree of accuracy. Other formats can

cause rounding errors up to 15 meters.

4.8.1 Editing Waypoints

Waypoints can be managed in Main Setup Menu/Waypoints. Briefly

press Enter to view the list of logged waypoints in alphabetical order. If

the list contains more than 6 waypoints, a down arrow at the lower

right edge of the list indicates that additional pages follow. To advance

to the next page, press the key; waypoints 7 through 12 are now

shown. Continue to press the key to view remaining waypoints in

groupings of 6.

To select and edit an individual waypoint within a group use the  or

 keys and press Enter. The first letter of the waypoint name will

blink; you can now change the first letter of the name of the waypoint

by using the  keys. There are numbers and letters, as well as a

set of special symbols, to choose from. With F1 you can switch

between capital and lower case letters, and numbers. Press the 

arrow key to acknowledge the character and move forward to the next

position. A waypoint name can be up to 16 characters long. Once the

waypoint name has been changed (or left as-is), confirm the name by pressing Enter. The

blinking cursor will now advance to the waypoint’s altitude field and that value can be altered

with the  keys. Press Enter to confirm any changes that you have made or accept the

existing value.

The blinking cursor will now advance to the degrees/minutes portion of the waypoint latitude.

The value can be changed with the  keys; however, degrees and minutes are linked so you

must scroll through all 60 minutes to advance to the next degree. Hold the  keys down to

change the values rapidly. Once the desired degrees/minutes are shown confirm by pressing

Enter. The cursor will now advance to the decimal minutes field and can be similarly set. Change

the value as necessary and confirm with Enter. The blinking cursor advances to the waypoint

longitude, which can be altered and confirmed in the same manner as the latitude.

4.8.2 Deleting Waypoints

To delete a waypoint, select it with  keys from the waypoint list and press F2 (Del WP). To

be on the safe side the 5020 will ask for confirmation by showing, “Delete Waypoint?” Use the

 keys to switch from “No” to “Yes”, and press Enter. The deletion process can be stopped by

Esc.

4.8.3 Inserting Waypoints

Within the Waypoint list press F1 (Ins WP) to add a new waypoint. Enter the waypoint name,

altitude, and position as described in 7.8.1 above. After you confirm all field entries with Enter,

the new waypoint will be inserted alphabetically in the waypoint list. The 5020 can store 200

waypoints.

Note: Newly entered waypoints can only be used after you have switched back to the normal

flight mode by briefly pressing F2. In addition, you cannot enter the new waypoints into an

existing route if it is active. If the route is active, first change into route selection mode by

pressing and holding Route, then pressing F2 (Can Rte) to deactivate the route.

4.8.4 Current Coordinate Indicator

Provided the 5020 is receiving a GPS signal, you can view your actual position can in the unit’s

Information Lines by pressing Enter. After twenty seconds the display will automatically revert to

the previous content. This function is useful after landing to relay your location to a person

coming to retrieve you.

4.8.5 Distance to Waypoint

The horizontal distance to a chosen waypoint that you have input manually with the Goto

function, or automatically with the Route function, can be displayed in the Dist to WP user field.

For distances under 6.2 miles (10 km) the resolution is 0.01 miles (10 m). For distances greater

than 6.2 miles (10 km) but less than 62.1 miles (100 km) the resolution is 0.1 miles (0.1 km).

Distances greater than 62.1 miles are shown as integer values (i.e., no decimal). The distance to

a waypoint is always measured to the center of the waypoint cylinder and not to its

circumference. For further information please read Section 7.9, “The Goto Function.”

4.8.6 Saving the Current Position

(Not available prior to V1.11)

You may wish to save your current position as a waypoint. To do this press and hold F1 for 3

seconds. As confirmation you will hear a double beep; the current coordinates will be stored in

the memory as a waypoint. The 5020 uses the letter M (for marker) for the waypoint designation

along with the date and time.

Example: M.22.04 11:16:49 for 22 April 11 hours, 16 minutes, and 49 seconds (UTC). Of course

this waypoint name can be changed to a more meaningful name in the Waypoints menu.

4.9 The Goto Function

Press and hold the Goto key to switch the lower portion of the

Vario screen into the Goto mode. The two closest waypoints

are shown with their distance in miles (km) from your current

position. The closest waypoint will be highlighted on top. Press

the  key to highlight the second closest waypoint; press the

 key again to see the next two closest waypoints, and so

on. A waypoint can be set as the active Goto by highlighting it

and pressing Enter. To deactivate the Goto function press F2

(Can Wp.).

If you encounter a strong cross wind on the way to a

waypoint/goal, you can find the optimal angle between your

destination and the wind by carefully changing your direction

of flight against the wind until the directional pointer in the

center of the compass rose points directly upwards, as shown

in the example to the right. By doing this you can be sure that

your flight path over ground is a straight line to goal and

consequently the shortest one — and you will avoid the well-

known “pursuit curve.”

Your altitude above/below your best glide (Alt a. BG) to the active Goto can be shown in a user

selectable field. While you are climbing in a thermal, Alt a. BG will display 0 when you have

Flytec 5020 Technical Manual

gained sufficient altitude to just be able to reach the waypoint/goal by flying at best glide speed.

Alt a. BG is based on the altitude entered in the altitude field for the active waypoint.

4.10 Flying Routes

A route is a sequence of waypoints. The waypoints used on a

route must first be entered into the 5020’s waypoint list. In

contrast to the Goto function where you must choose the next

waypoint from a long list by pressing and holding Goto, you

can advance or move back to a previous waypoint in a route

with the  keys. This expedited route manipulation is

accessed with F1 (Nxt Fnc).

To select a route for flying, press and hold Route for a few

seconds; a list of the existing routes will appear in the lower

portion of the display. Use the  keys to select the desired

route and then press Enter to make it active. To create,

change, or delete a route please read Section 7.11, “Routes:

Create — Delete — Alter.”

The 5020 can store up to twenty routes. The same waypoint

can be used more than once along a route, and the same

waypoint may occur on other routes as well. If a waypoint is

used in a route, it cannot be deleted from the waypoint list until the route is deleted. When there

is an active route it is possible to look up other, possibly closer, waypoints without leaving the

current active route, by using the Goto function.

Starting with firmware version 1.12 it

is possible to display the distance

around the remaining waypoints in a

route (Dist Gl), calculated from your

current position. Additionally, it is

possible to show the altitude above

goal (Alt a. Gl) around the remaining

waypoints in a route, calculated from

your current position. This calculation

takes the windspeed and direction

into account, which was previously

derived from flying smooth, full

circles. When calculating Alt a. Gl it is

assumed that you will fly on the courseline between the remaining waypoints, and that you will

fly at best glide speed. Even with these two assumptions Alt a. Gl is a very approximate value

because the instrument does not know the precise wind conditions along the balance of the

route and how you will fly on the way to goal. Nonetheless this can still be useful information.
