B
Format is as follows: Configuration Option; Configuration Option Description.
A. Display Intruder Limit; 3 (Minimum) Display Intruder Limit 30 (Maxi-
mum), incremented by 1.
The Display Intruder Limit Program is used to limit the number of
intruders displayed in the aircraft. The Display Intruder Limit will be
configured to a value between 3 (minimum FAA requirement) and 30
(max. intruder limit).
The TAS Processor will transmit a maximum of 30 intruders to the traffic display.
B. Heading Type; Synchro Data or ARINC 429 Data
The Heading Type Program will indicate the type of heading source
(either ARINC 429 or Synchro) that interfaces to the TAS.
C. Attitude Type; Not Installed or ARINC 429 Data.
ARINC 429 magnetic heading (BCD or Binary), pitch angle and roll are
input to the TAS Processor via the Attitude/Magnetic Heading ARINC
429 high speed input bus.
D. Radio Altimeter Type; Not Installed, ARINC 429, Bendix/King Analog,
Sperry Analog, Collins Analog, or ARINC 552A.
The Radio Altimeter Source Port will input to the TAS Processor. The
input impedance into this port is 55 Kohms. The port has an associ-
ated Radio Altitude Valid input to the TAS Processor.
Radio Altimeter Valid input will be 20 to 30 VDC during proper altime-
ter operation (if present). Any failure of the altimeter causes the valid
signal to become an open circuit. The analog radio altimeter input (if
present) will be considered failed if the valid input pin is in the failed
state.
The Radio Altimeter Type Program will indicate which type of radio
altimeter input is used.
