Piper PA28-181 AFM SUPPLEMENT
SECTION 1 - GENERAL
1.
The Garmin GTX 330 panel mounted Mode S Transponder is a radio
transmitter and receiver that operates on radar frequencies, receiving
ground radar or TCAS interrogations at 1030 MHz and transmitting a
coded response of pulses to ground-based radar on a frequency of
1090 MHz. The GTX 330 is equipped with IDENT capability that
activates the Special Position Identification (SPI) pulse for 18
seconds. Mode S transmit/receive capability also requires 1090 MHz
transmitting and1030 MHz receiving for Mode S functions.
\In addition to displaying the code, repiy symbol and mode of
operation, the GTX 330 screen will display pressure altitude, density
altitude, temperature, and timer functions, depending on equipment
connections and configuration selection. The unit also features an
altitude monitor, Traffic Information Service (TIS) traffic advisories
and flight timers. A voice or tone audio output announces altitude
deviation, TIS traffic advisory and count down timer expiration.
SECTION 2 - LIMITATIONS
1.
Display of TIS traffic information is advisory only and does not relieve
the pilot responsibility to "see and avoid" other aircraft. Aircraft
maneuvers shall not be predicated on the TIS displayed information.
Display of TIS traffic information does not constitute a TCAS | or
TCAS |! collision avoidance system as required 14 CFR Part 121 or
part 135.
Title 14 of the Code of Federal Regulations (14 CFR) state that
"When an Air Traffic Control (ATC) clearance has been obtained, no
pilot-in-command (PIC) may deviate from that clearance, except in an
emergency, unless he obtains an amended clearance." Traffic
information provided by the TIS up-link does not relieve the PIC of
this responsibility.
