(q) Above/Normal/Below Test
Using the TCAS Ramp Test Set, create scenario 1 to simulate an approaching 
Mode C transponder equipped aircraft beginning at 10 nautical miles, an altitude of 
12,000 feet, a closure rate of +450 knots, a 0 degree bearing, and an altitude rate 
of 0 feet per minute.
1 Set RA No. 1 to 2500 feet and pressure altitude of No. 1 and No. 2 air data 
systems to 5000 feet.
2 Set Above/Normal/Below switch to ABOVE.
3 Observe target intruder appear as proximate traffic in 12 o’clock position on 
TA/VSI +7000 ft.
4 Change the pressure altitude of  No. 1 and No. 2 air data system to 10,000 feet.  
Using the TCAS Ramp test set, create scenario 2 to simulate approaching Mode 
C transponder equipped aircraft beginning at 10 nautical miles, an altitude of  
3000 feet, a closure rate of  +450 knots, a 0 degree bearing, and an altitude rate 
of 0 feet per minute.
5  Set Above/Normal/Below switch to BELOW.
6 Observe target intruder appear as proximate traffic in 12 o’clock position on 
TA/VSI – 7000 ft.
7 Set  Above /Normal/Below switch to NORMAL and observe intruder disappear 
from display.
8 Change pressure altitude of No. 1 and No. 2 air data systems to 3000 feet and 
repeat scenario 2 in test 100.  Observe intruder on display as proximate traffic in 
12 o’clock position,  0 feet.
