3.5.7 FUNCTION 7: SET GROUND
The "Set Ground" function is used to indicate to the 6300-M4 the ambient "Ground" pressure.
Before connecting the 6300-M4 to the aircraft, just after the Self Test has been performed, it is
recommended that this function be invoked. The Pitot and Static ports must still be open to
ambient when using this function. When the "GO" key is pressed in the screen shown below,
the 6300-M4 will "memorize" the ambient pressure it measures, as the "Ground" pressure.
This will be used later when the "Go To Ground" function is invoked.
Press "GO" to Set Ground ;
or press "CANCEL" to exit.
3.5.8 FUNCTION 8: GO TO GROUND
The "Go To Ground" function is used to bring the aircraft back down to "Ground". The
target altitude is set to the value "memorized" in the "Set Ground" function and the target
airspeed is set to 20 knots and the 6300-M4 ramps towards these targets. Once these targets
have been achieved, you must put the 6300-M4 into Measure mode on both outputs and only
then disconnect the 6300-M4 from the aircraft. The "Go to Ground" screen is shown below.
When "GO" is pressed, the 6300-M4 shows the Main screen. This screen is shown below, with
the new targets of 100 knots and 275 feet. This assumes that the "Ground" pressure was 275
feet when the "Set Ground" function was invoked.
