What do the markings on the wings indicate regarding the flaps?

The markings on the wings of the Beechcraft Travel Air BE-95 serve a specific purpose related to the operation of the flaps. These markings indicate the deflection angles for the flaps, typically set at 10 and 20 degrees. Understanding flap deflection is crucial for pilots as it directly affects the aircraft's lift and drag characteristics during different phases of flight, particularly takeoff and landing.

When pilots reference these markings, they can effectively adjust the flap positions to optimize the aircraft's performance. This capability is essential for maintaining control and ensuring safe operational limits concerning speed and lift during various maneuvers. The other options, while they might relate to flight operations, do not pertain to the wing markings as they specifically relate to flap settings.
