What mode should be selected while operating in single engine situations?

• A. OFF
• B. RA only
• C. TA only
• D. TA and RA

Answer: (C)

In single-engine operations, you need to manage altitude and flight path manually without automatic guidance that could conflict with the engine-out procedure. Terrain Awareness and Warning System has two levels: TA provides terrain warnings and alerts to help you stay aware, while RA would issue urgent, maneuvering instructions to avoid terrain. If you were to rely on RA during a single-engine situation, the required climb or descent guidance could conflict with what you’re doing for the engine-out procedure and the aircraft’s reduced performance. TA only keeps you informed about terrain risk without pushing you into a maneuver, allowing you to apply your own decision-making and maintain safe flight path. The other options either remove warnings or add active avoidance guidance that isn’t desirable in this scenario.
