Cal:
During the factory calibration a factor has been determined and entered here that will give you accurate airspeed,
provided your pitot tube is not influenced by pressure effects caused by airflow around your airframe. The calibration is
displayed in % of the reading, you can increase or decrease the reading if required to help cancel out under or over
reading of the airspeed indicator on your aircraft. The original calibration factor has been written onto the back of your
instrument.
4.3 Timers Setup
FLIGHT:
Select whether you want the ASI-4 to automatically detect a flight or whether the pilot must press the F1/Up button to
start/stop a flight. We recommend you select automatic flight detection.
T/O AIRSPEED:
This menu option is only shown if the “DETECT” flight mode is selected. Enter the takeoff airspeed threshold that you
want the flight timer to start incrementing.
