Connect the radio altimeter test set to the airplane. S 865-335
(11)
Set the radio altitude to 550 feet. NOTE: The airplane must be in the air mode before you increase
____ the radio altitude or the TCAS will fail.
(a) Make sure the ND shows the TA ONLY indication. S 865-019
(12) Set the radio altitude to 2400 feet. NOTE: Increase the radio altitude by 600 feet per minute (fpm) or
____ less. RAs are inhibited below 600 feet during climb with TCAS change 7.0 and 1100 feet with TCAS change 6.04a. So TA ONLY will show at low altitude.
(a) Make sure the TA ONLY indication clears from the ND when the radio altitude is greater than 1100 feet.

INTRUDER TYPE: ATCRBS ALT = ON
(b)
RANGE: 8.0 nm RATE: +500 kt
(c)
ALTITUDE: 39,900 ft RATE: 0 fpm
NOTE: Make sure the vertical separation between the airplane
____ and the intruder is about or slightly less than 100 feet. You can change the airplane's altitude or intruder setup on the test set to achieve this.

(21) Push the RUN/STOP key to start the test, and look for this sequence on the ND, PFD, and flight compartment speaker:
(a) The intruder moves down the 45 degree bearing mark to the
center of the ND.
(b) The intruder has the correct relative altitude.
NOTE: The relative altitude shown can be -00 or -01 depending____
on your actual vertical separation. This is because
TCAS can only display relative altitude by 100 foot
increments.
(c) The intruder begins as Non-threat Traffic (open white diamond).
(d) The intruder changes to Proximate Traffic (solid white diamond)
(e) The intruder changes to a Traffic Advisory (solid yellow
circle).
(f) The TCAS gives a "TRAFFIC, TRAFFIC" voice announcement on the
flight compartment speaker.
(g) The intruder changes to a Resolution Advisory (solid red
square).
(h) The TCAS gives a "CLIMB, CLIMB" or "CLIMB, CLIMB, CLIMB" voice
announcement on the flight compartment speaker.
