What are the VFE airspeeds for flaps 10°, 20°, and 30°?

The VFE airspeeds, or the maximum flap extended speeds, are critical for ensuring pilot safety when flying with flaps extended. These airspeeds vary depending on the configuration of the flaps, and knowing them helps prevent potential structural damage to the aircraft from exceeding recommended limits while using the flaps.

In this case, the correct airspeeds provided in answer B (210 knots for flaps 10°, 210 knots for flaps 20°, and 175 knots for flaps 30°) are consistent with standard operating procedures for aircraft in the DFW training program. This means that the aircraft can safely fly at these speeds with respective flap extensions without risking a stall or system error, allowing pilots to handle the aircraft effectively during takeoff and landing phases.

Understanding VFE is essential for flight safety, as exceeding these speeds while the flaps are extended could lead to loss of control or damage to the aircraft. Therefore, recognizing the correct VFE airspeeds helps pilots maintain safe operational practices during various phases of flight.
