NOTES
1.
If the display reflects a gross error in target bearing, check the directional
antenna cables at TRC connectors J9 (sum port) and J11 (difference port).
They may be reversed. A further indication of this condition would be a
target that moved in a counter-clockwise direction when the test set is moved
in a clockwise direction.
2.
Multiple targets or a faulty bearing may result from multipath distortion.
3.
During these tests, the SKY899 may detect and display other active targets.
e.
Repeat a, b, c, and d from each of the test points (see step 18).
20. Do the following dynamic test.
a.
Position the ramp test set on the test point directly in front of the test aircraft (i.e.,
approximately 100 ft (or less) in front of the aircraft, see step 18).
b.
Connect the TCAS-201 Flat Antenna (facing towards the test aircraft) to the antenna connector.
c.
At the TCAS-201 test set, press the SCEN key.
d.
Initiate the SCENARIO TEST by pressing the ANTENNA push button switch or the
RUN/STOP key.
e.
Verify that the display shows an "other traffic" symbol (open diamond) at the 12 o'clock
position (±30 degrees) approximately 5.0 nm and in level flight. The traffic symbol should be at
an altitude of 500 ft above own aircraft (i.e., "+05") and moving towards your aircraft.
f.
When the target approaches closer than approximately 1 nm from own aircraft, verify that the
symbol changes from an other traffic symbol (open diamond) to a traffic advisory (solid circle).
NOTE
The voice message, “TRAFFIC, TRAFFIC,” will be enunciated over the
cockpit audio system.
g.
The target, when it reaches 0.0 nm, will reverse direction and move outbound on the same
heading.
NOTE
The target may momentarily drop from the display and then reappear as
other traffic symbol (open diamond).
