What does the indicator light for "flaps" show?

• A. Altitude adjustment
• B. Position of the flaps
• C. Engine temperature readings
• D. Navigation settings

Answer: (B)

The indicator light for "flaps" serves the important function of showing the position of the flaps on an aircraft. Flaps are movable panels on the wings that extend and retract, altering the wing's curvature and surface area to enhance lift during slow flight phases, such as takeoff and landing. The indicator light provides real-time information about whether the flaps are deployed, retracted, or in an intermediate position, which is crucial for pilot awareness when managing airspeed and approach configurations.

Understanding the position of the flaps directly impacts flight safety and performance, allowing pilots to ensure they are set correctly before takeoff or landing. Other indicators, like altitude adjustment, engine temperature readings, or navigation settings, do not relate to the operation of the flaps and thus are not relevant to the functions provided by the flaps indicator light.
