9) Shortly after the intruder reaches the airplane symbol on the ND, TCAS gives a "Clear of Conflict" voice announcement on the flight compartment speaker for T-49 with Rev 3.2 software.
(7) S 215-098Set the intruder type switch on the T-49 to the TCAS position.
(8) S 865-324Push the interrogate switch. (a) Make sure the T-49 display shows the correct intruder type.
(9) S 865-325Push the interrogate switch to start the scenario. (a) Make sure the T-49 display shows the airplane's altitude |100 feet and the correct scenario (Range 14 nMi, Co-Altitude, Closure rate 720 kts).
S 865-049
(10) Decrease the airplane's altitude by 200 feet.
(a) Make sure this sequence shows on the ND, PFD, and flight compartment speaker: 1) The intruder descends to the airplane symbol from the 45
degree bearing makr.
2) The intruder begins as Non-threat Traffic (open white diamond).
3) The intruder changes to Proximate Traffic (solid white diamond).
4) The intruder changes to a Traffic Advisory (solid yellow circle).
5) The TCAS gives a "TRAFFIC, TRAFFIC" voice announcement on the flight compartment speaker.
6) The intruder changes to a Resolution Advisory (solid red square), and gives a "DESCEND, DESCEND, DESCEND" voice announcement on the flight compartment speaker.

7) The PFD shows a vertical resolution to push down.
8) Before the intruder gets to the closest point of approach, the TCAS possibly will give an "increase descent" voice announcement on the flight compartment speaker.
9) Shortly after the intruder reaches the airplane symbol on the ND, TCAS gives a "Clear of Conflict" voice announcement on the flight compartment speaker for T-49 with Rev 3.2 software.
10) The PFD shows a vertical resolution to push down.

(11) Set the transponder select switch on the control unit to the R or 2 position.
G. High Altitude Climb Inhibit Test
S 865-107
(1)
Use the pitot/static test set to make a simulated altitude of 49,000 feet.
S 725-108
(2)
Do the previous TCAS intruder scenario test again.
(a) Make sure TCAS does not give a CLIMB corrective action.
S 865-332
(3)
Return the airplane back to field level altitude.
S 865-051
(4)
Set the radio altitude to 0 feet.
NOTE: Decrease the radio altitude by 600 feet per minute (fpm) or
____ less. RAs are inhibited below 900 feet during descent iwth TCAS version 6.04a. RAs are inhibited below 400 feet during descent with TCAS change 7.0. So TA ONLY will show at low altitude.
(a) Make sure the ND shows the TA ONLY indication when the radio altitude is less than 400 feet.
