True or False: Propeller reverse is called when 1-1 is at OGE.

• A. True
• B. False
• C. Not enough information
• D. Irrelevant

Answer: (A)

Propeller reverse is used to help slow the aircraft after landing, once on the ground and in a configuration that allows reversing thrust without compromising control. Saying it’s called when the rotor is at “1-1” while in ground effect (OGE) describes a specific, safe ground-condition state where engaging reverse thrust is appropriate to aid deceleration. In training terms, that moment is the correct time to apply reverse thrust to enhance braking and shorten the landing run, so the statement is true. Not enough information isn’t necessary here because the scenario describes a concrete condition in which reverse thrust would be used, and false would contradict standard landing procedures. Irrelevant doesn’t apply because reverse thrust is directly related to landing deceleration.
