Initiate the intruder scenario and observe the following:
•
The simulated intruder should be acquired at approximately 6-10 NM at 90 degree
bearing. Observe intruder closes on own aircraft at a rate of 0.1 NM/sec. Verify
that only a single simulated target is displayed in the expected quadrant (exclude
possible local traffic).
•
The simulated intruder should transition from Other Traffic (displayed as an open
diamond with +03 displayed above), to proximate traffic (displayed as a filled
white diamond with +03 displayed above), to a Traffic Advisory (TA) alarm (yellow
filled circle with +03 displayed above.)
•
For GTS 8000 TCAS II installations, the following applies:
The simulated intruder should transition from a Traffic Advisory (displayed as a
solid yellow circle with +03 displayed above), to a Resolution Advisory (RA) alarm
(red filled square with +03 displayed above). Additionally, a Resolution Advisory
is displayed on the vertical speed tape of PFD1 and PFD2 and an audible
Resolution Advisory is heard over cockpit speakers and headphones.
The aural TA annunciations are muted if the gear is extended and the
Radar Altimeter indicates below 400 feet.
For GTS 8000 TCAS II, to generate a DESCEND resolution advisory, the
WOW actuators must be set to the in-air position and the Radar Altimeter
must read greater than 2,000 feet.
At the end of these tests, put the aircraft back 'on-ground' and restore radar altimeter operation.
