What is the role of GPWS in ensuring terrain clearance?

GPWS protects terrain clearance by actively monitoring the aircraft’s position relative to the ground and potential obstacles, and by warning the crew when a conflict is likely. It uses inputs like altitude, attitude, and proximity to terrain to generate audible cautions such as “Terrain, Terrain” and “Pull Up,” and it can provide advisories that guide the pilot to take corrective action to gain altitude. The system is designed to prompt an escape maneuver when a safe climb is required to avoid a collision with terrain, giving crews time to react before thresholds are breached. This is precisely what the option describes: it provides terrain/obstacle warnings and advisories and prompts escape maneuvers. Other choices refer to systems outside GPWS, such as engine fault tones, tuning navigation radios, or managing fuel distribution.
