Revision G 190-00207-02
FORMAT (Altitude Format)
This field determines how the pressure altitude is shown on the GTX 330 display.
SELECTION DESCRIPTION
FLIGHT LVL
(Flight Level)
DEFAULT. The pressure altitude is displayed in hundreds of feet. For
example, a pressure altitude of 12,300 feet is displayed as “FL 123”.
FEET
Pressure altitude is displayed in feet.
METERS
Pressure altitude is displayed in meters.
VFR ID (VFR Transponder Code)
This field is the four-digit code that is selected when the user presses the GTX 330 VFR key. In the
United States, 1200 is the VFR code for any altitude. The default is set to 1200.
ALTITUDE ALERT DEVIATION (Altitude Format)
This field determines the amount of altitude difference from selected altitude to generate an altitude alert
deviation. It is set to 200 feet, the minimum altitude, at the factory.
SQUAT SWITCH
The squat switch field may be set to either YES or NO.
Selecting YES in this field sets the GTX 330 to use the squat
switch to determine lift off. Selecting NO sets the GTX 330 to use Automated Airborne Determination
from other sources.
DELAY TIME
This is the number of seconds the aircraft must be on the ground before the GTX 330 automatically
switches to GND mode when it has a means of determining the aircraft is on the ground. It has a range of
0 (zero) seconds to 99 seconds, with the default set to 24 seconds.
AUTO FLIGHT TIMER
Available choices are MAN, CLEAR and ACCUM. Selecting CLEAR resets flight time to zero and
starts the flight timer when lift off is sensed.
Selection Description
MAN
Manual selection. DEFAULT. Flight timer START/STOP is controlled
manually by the pilot.
CLEAR
Automated flight timer START/STOP resets to zero at every lift off.
ACCUM
Automated flight timer START/STOP accumulates, meaning, it continues
counting up at lift off.
