• Scenario 4 b: Low Altitude Don't Allow Increase Descent
• Scenario 4c: Low Altitude TA Only.
NOTE
(1) There may be an approximately one second delay between symbol display and the aural advisory.
(2) The maximum clim b altitude is docum e nted at airplane certification and may be different than the airplane
service ceiling. Consult airplane data for applicable altitude. This altitude is programmed in the ECU.
4.9.2.5.1. S
cenario 1a: Climb RA. In Scenario 1a, the intruder is placed below own airplane to induce a CLIMB RA command.
a. Set the airplane under test (UUT) simulated altitude to 12,000 ft and the radio altimeter to maximum setting.
b. Set the following values as necessary:
•TCASType:TCASII
• Intruder Type: Mode S
• Range at Start: 15.00 nmi
• Range Rate: +720 kts
• Altitud e at Start: 11900 ft (if entering as an absolu te altitude) or -100 ft (if entering relative altitude)
• Altitude Rate: 0.
c. S tart the scenario.
d. Monitor the TCAS d isplay and au dio s ystem for correct presentatio n as follows (NO T E 1):
Display Range (approx) Display Aural
12 nmi Other Traffic Symbol None
9 nmi TA Symbol TRAFFIC, TRAFFIC
6 nmi RA Symbol CLIMB, CLIMB
4.9.2.5.2. Scenario 1b: Descend RA. In Scenario 1b, the intruder is placed above own airplane to induce a DESCEND RA
command.
a. Set the airplane under test (UUT) simulated altitude to 12,000 ft and the radio altimeter to the maximum sett ing.
b. Set the following values as necessary.
•TCASType:TCASII
• Intruder Type: Mode S

• Altitude at Start: 12,100 ft (if entering as an absolute altitude) or +100 ft (if entering relati ve altitude)
• Altitude Rate: 0.
c. S tart the scenario.
d. Monitor the TCAS d isplay and au dio s ystem for correct presentatio n as follows (NO T E 1):
