Use. The function will be useful for pilots flying with a winch and participating in competitions.
Often during the competition, the winch acts as a conveyor, and it is desirable to minimize the
tightening time of each wing. This function allows you to give a long beep after passing certain,
determined in advance by the rules of the competition height threshold on climb, and do not
waste time on an extra lift.
MENU 10
Variometer mode switch. The device has two possible
vario modes: «Standard» and «Thermal»
. When the device is turned on, the initial value
is set to "Standard". When the "Thermal" position is selected, the variometer switches to a
more sensitive mode of operation, but this can lead to an increase in the probability of false
positives, and this should be used with caution.
Use. The "Standard" mode is suitable for most flight situations, including: free flights in
dynamic flows, motor flights, etc. However, in thermal flows, when a rapid response of the
variometer is required, it is recommended to set the "Thermal" mode.
WARNING! The "Thermal" mode is in the testing stage and in real thermal flows at the time of
writing this instruction was not checked.
MENU 11
Turn ON/OFF the LCD backlight. The ON/OFF value is
selected by briefly pressing the "Button 3". The initial
value is set to "ON" when the device is turned on.
Use. When flying during daylight hours, it is recommended to turn off the screen backlight to
save energy. Based on the tests performed, in the daytime the values from the screen without
the backlight are read no worse than with the backlight.
Additional information
To reduce the firmware development time, the algorithm of the variometer averager was
borrowed from these two awesome projects:
