Increase Descent RA's are inhibited below 1,450 ft AGL when descending.

Increase Descent RA's are inhibited below 1,450 ft AGL when descending.

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (A)

Understanding TCAS RA behavior: certain resolution advisories are limited by altitude to keep maneuvers feasible near the ground. On the A320, an Increase Descent advisory is not issued when you are descending and below about 1,450 ft AGL. This inhibition prevents forcing a steeper descent in the final approach or at very low altitudes, where there isn’t much vertical room to recover and where terrain or runway considerations are critical. If traffic requires, other advisories (like descend without the “increase” qualifier or climb/maintain) may still be issued, but the specific instruction to increase descent is suppressed to maintain safe, manageable flight near the ground.
