When is propeller reverse called?

• A. When 2-2 is at OGE
• B. When 1-1 is at OGE
• C. When 4-4 is at GE
• D. When 3-3 is at OGE

Answer: (B)

Propeller reverse thrust is a ground‑deployed braking function—it’s used after the aircraft has touched down to help slow the airplane during the landing rollout. The scenario described in the correct choice matches the condition where the propeller is in the reverse range (the 1-1 setting) and the aircraft is in On-Ground-Effect, meaning you’re in the phase where reverse thrust has the necessary authority and safety margin to help decelerate on the runway. Using reverse thrust while airborne would be unsafe and typically unnecessary, so it’s reserved for after touchdown. The other conditions imply attempting reverse in flight or in states where it wouldn’t be effective or safe, which is why they’re not the correct context.
