SQUAT SWITCH
The GTX 327 Flight Time may be based on the squat switch state. The squat switch field may be set to
either YES or NO. (Default NO). If YES, sense may be set to HIGH or LOW. If set to NO, airborne
status for auto standby and flight timer features will be determined by input data. The highest priority is
GPS groundspeed. The next is serial port ADC input followed by pressure altitude change, if no other
RS-232 source is available.
SENSE (Squat Switch Sense)
This field can only be entered if the AIRBORNE SOURCE selection is YES.
Selection Description
LOW DEFAULT. The installed squat switch or airspeed switch is low
(grounded) when the aircraft is on the ground, and open when airborne.
HIGH The installed squat switch or airspeed switch is open when the aircraft is
on the ground, and low (grounded) when airborne.
AUTO STANDBY?
Selection Description
OFF Selection of STBY (standby) and ALT (altitude-reporting) modes is
initiated manually by the pilot.
ON
DEFAULT. The GTX 327 will automatically transition from STBY to
ALT when the unit determines the aircraft has become airborne. When
the unit determines the aircraft has been on the ground ("ground-borne")
for the configured delay time (see "Delay Time", below), the unit will
automatically transition from ALT (or ON) to STBY.
Delay Time
This is the number of seconds the aircraft must be on the ground before the AUTO STBY feature
automatically switches the unit to STBY mode. Delay Time has a range of 0 (zero) to 99 seconds, and is
set to 24 seconds at the factory. When the unit is configured with a SQUAT SWITCH, an additional air-
state delay time (4.5 seconds for fixed-wing; 1 second for rotorcraft) is added to this user-configured
delay time for ground-borne determination.
