All TA aural alerts are inhibited below ______ AGL when ascending.

All TA aural alerts are inhibited below ______ AGL when ascending.

• A. 400'
• B. 800'
• C. 1000'
• D. 600'

Answer: (D)

During TCAS operation, there are two alert types: TA, which briefly informs you that nearby traffic is present, and RA, which gives immediate guidance to avoid a collision. When the aircraft is in a climb, TA alerts are suppressed until you reach a small height above the ground. This keeps you from being overwhelmed by traffic advisories during the critical takeoff and initial climb, where attention is focused on flight path and engine performance, while still allowing urgent RA warnings to surface if a collision risk exists. The fixed low-altitude threshold is chosen to balance reducing nuisance alerts with maintaining safety, so you aren’t distracted by non-critical traffic information during ascent, but still receive prompt action-ready alerts if needed.
