TRANSPONDER STATUS BAR
The Transponder Status bar displays the transponder
code, reply symbol, and mode of operation. TIS (Traffic
Information System) surveillance data up-linked by Air
Traffic Control (ATC) radar through the GTX33 Mode
S Transponder appears on the Inset Map (PFD), Navi-
gation and Traffic Map Pages on the MFD (refer to the
Multi Function Display Pilot’s Guide). If the transponder
is configured with Automated Airborne Determination,
normal operation begins when lift-off is sensed. When
the aircraft is on the ground, the window automatically
displays “GND”. The transponder does not respond to AT-
CRBS interrogations when GND is annunciated. If a delay
time is set in Configuration Mode, the transponder waits
a specified length of time after landing before changing to
GND mode.

Pressing the XPDR softkey displays the second-level
softkeys:
• STBY – Selects standby mode. When in standby
mode, the transponder does not reply to any
interrogations.

• ON – Selects Mode A. In this mode, the transpon-
der replies to interrogations, as indicated by the
Reply Symbol (R). Replies do not include altitude
information.

information.
• ALT – Selects Mode C. In ALT mode, the tran-
sponder replies to identification and altitude
interrogations, as indicated by the Reply Symbol
(R). Replies to altitude interrogations include the
standard pressure altitude received from an external
altitude source (not adjusted for barometric pres-
sure). The ALT mode may be selected in aircraft
not equipped with an optional altitude encoder;
however, in this case, the reply signal only replies
to mode A interrogations. The transponder also
responds to interrogations from TCAS-equipped
aircraft.

• VFR – Sets the transponder code to the pre-pro-
grammed VFR code selected in Configuration
Mode (this is set to 1200 at the factory in the
U.S.A. only; please refer to ICAO standards for
VFR codes in other countries).

• CODE – Displays the transponder code selection
softkeys, which includes the digits 0-7 and BKSP.
• IDENT – Pressing the IDENT softkey activates
the Special Position Identification (SPI) Pulse for
18 seconds, identifying the transponder return on
the ATC screen.

Transponder Code Selection
Transponder code selection is performed with eight
softkeys (0-7) providing 4,096 active identification codes.
Pushing one of these softkeys begins the code selection
sequence. The new code is activated five seconds after the
fourth digit is entered. Pressing the BKSP softkey removes
one digit at a time until the status bar is empty (refer to the
Mode S Transponder Pilot’s Guide).
