Which GPWS mode is associated with Unsafe terrain clearance when not in landing configuration?

• A. Mode 4
• B. Mode 2
• C. Mode 5
• D. Mode 1

Answer: (A)

GPWS warnings come in distinct modes that target different risky situations. The one that signals unsafe terrain clearance when you’re not in a landing configuration is Mode 4. It is triggered when terrain is a threat while the airplane isn’t set up for landing (for example, flaps or gear not in the landing position), so the system warns you to avoid a collision with terrain because your configuration suggests you may not have the appropriate approach parameters for a safe glide path. This focus on your configuration distinguishes it from other modes: Mode 1 is about excessive descent rate, Mode 2 about rapid terrain closure, and other modes cover different alert scenarios. So Mode 4 is the correct association for unsafe terrain clearance when not in landing configuration.
