Which maneuvers are prohibited when the landing gear, flaps, or speed brake are extended?

The correct answer focuses on the prohibition of spins when the landing gear, flaps, or speed brake are extended. Spins require very specific aerodynamic conditions to be properly initiated and recovered from. When these control surfaces are deployed, they create additional drag and change the aircraft's aerodynamics, which can significantly alter its behavior. This can lead to an increased risk of uncontrollable spins under these circumstances, making it unsafe to perform such maneuvers with those components extended.

In general, certain flight maneuvers can compromise the safety and performance of the aircraft when specific configurations (like extended landing gear, flaps, or speed brakes) are in use. With the landing gear down, for instance, the aircraft is already in a more drag-heavy configuration, which could impede recovery from spins.

Understanding such prohibitions ensures that pilots are well-aware of the aircraft's limitations and can maintain safe operational procedures.
