Which flap detent position provides SLATS 25 (Full)?

The correct choice is associated with the flap detent position that allows for maximum configuration of slats and flaps, specifically SLATS 25 (Full). In aviation, different flap detent positions correspond to specific configurations of the aircraft, affecting performance, lift, drag, and stall characteristics.

Flaps 30 is the appropriate detent position for achieving SLATS 25 (Full) because it typically allows for the full extension of slats and corresponding flaps, which enhances the aerodynamic profile of the wing during takeoff and landing procedures. This configuration helps to increase lift at lower speeds, providing the necessary support for safe operation during critical phases of flight.

Other detent positions listed do not correspond to the Slats 25 (Full) configuration. Position 1 and Position 20 generally refer to less extended configurations, which do not provide the full benefits of the extended slats and flaps necessary for achieving SLATS 25. Position 45, while potentially suggesting a greater flap extension, is not typically relevant for SLATS 25 but rather exceeds the standard configurations used for takeoff and landing scenarios. Thus, understanding the relationships between flap detent positions and their corresponding aerodynamic effects is key to identifying the appropriate configuration for various flight phases.
