Operating Modes
The lower number shows the difference to the set altitude. Negative values mean altitudes
below set altitude. The upper yellow number indicates the number of seconds left to be
below the set altitude. Chevrons indicate meters below or above required altitude. Each
line represents 10 m. A message
you fulfil the conditions.
5.7.2.3.3 Maximum Start Speed and/or Maximum Start Altitude
A lot of competitions are limiting the start altitude and/or start ground speed. The system
helps pilots to cross the start line at the correct altitude with correct ground speed. Enter
Start alt. and/or Start gsp. to use this option. An indication will be shown on the final
glide symbol. Character "A" will be displayed before the MacCready value if a start altitude
was entered and/or character "G" will be displayed if a start speed was specified. AG
combines both A and G.
The lower number indicates at what altitude you will reach start altitude. A negative value
indicates you are going to be there below the required start altitude.
The arrival altitude to start is not based on MacCready, the glider nor the wind
settings. It is calculated based on energy difference during flying straight. This
gives a very precise estimate at what altitude you will arrive at the start.
Speeding up will result in greater energy loss and the arrival altitude will decrease;
slowing down to best glider ratio will decrease energy loss and the arrival altitude
will increase.
