9 Flying with the system
To get the best out of the unit, it is import ant that some preparation is done prior to the flight.
Pre-flight preparation will ensure that the flight will be both successful and enjoyable.
9.1 Flight preparation on ground
- Check if you have desired TP data base uploaded.
- Prepare a task.
- Enter flight recorder information (pilot name, surname, glider type, recording interval...).
9.2 Before take-off
- Switch the unit ON at least 3 minutes before take-off (this will ensure sufficient GPS reception
and will create a base line of the baro trace).
- Select correct pilot (many settings belong to pilot) on initial setup.
- Check task if it is correct after using of Task setup.
- The active task during take-off will be automatically declared in flight recorder.
9.3 During flight
The unit hardware and firmware concept are so far optimized that the pilot doesn't spend too
much time to operate the unit during flight. A very significant indication that shows that the
unit has changed to flying mode is Logbook replacement with statistics page.
9.3.1 Set QNH
The pilot should input actual QNH value of the airport where he will take-off. This action should
be carried out on ground, after take-off, change of QNH in main page quick setup menu will ad-
just altitude reading to actual QNH setting.
9.3.2 Wind calculation
Unit is able to measure wind under two different methods. Wind calculation results are shown
on wind indicator which is part of many pages. Unit will switch between straight and circling
method automatically and history of wind will be counted in new calculations.
Circling: Calculation is based on ground speed change due to wind influence in circling. The
method is active exclusively during climbing process. The process start automatically after circ-
ling is detected. The method is based on fact that the ground speed is affected by the wind. GS
is maximal by tailwind and minimal by head wind. This phenomenon is used by GS difference
calculation method.
