Which flap settings are authorized for takeoff?

• A. 1, 3, 6, 9, 12
• B. 0, 1, 2, 3
• C. 1, 5, 10, 15, 25
• D. 1, 5, 10, 15

Answer: (C)

Takeoff performance relies on getting enough lift without adding excessive drag, and the aircraft’s operating limitations specify exactly which flap positions can be used for a takeoff. The P-8A designates a specific subset of flap settings that are approved for takeoff to ensure safe liftoff margins, adequate rotation authority, and proper stall protection across the range of weights and runway conditions.

The approved takeoff flap positions are 1, 5, 10, 15, and 25. These settings provide a range from light to high lift, allowing a takeoff to be performed safely whether you’re light or heavy, on a long runway or a shorter one, or under varying winds. Using any other flap setting for takeoff isn’t authorized by the flight limitations, which is why options that include 0 or other non-listed values aren’t correct.
