Which of the following is not a flap limitation for takeoff in a Cessna 152?

When considering flap limitations for takeoff in a Cessna 152, it's important to refer to the manufacturer's guidelines and operational procedures for the aircraft. The recommended flap settings for takeoff typically include configuration possibilities of up to 10 degrees of flaps.

Using the maximum flaps setting of 15 degrees for takeoff can lead to performance issues such as increased drag and reduced climb performance, which may not be suitable for most takeoff scenarios. When flaps are set at 0°, 5°, or 10°, they can help enhance lift while maintaining a balance with drag, thus optimizing the aircraft's takeoff performance.

Therefore, the option that states 15° is not a flap limitation for takeoff reflects that it is generally not recommended to use this degree of flap setting during takeoff in a Cessna 152, making it the correct answer in this scenario.
