What is the maximum indicated airspeed for Flaps 1?

• A. 230 kts
• B. 250 kts
• C. 180 kts
• D. 220 kts

Answer: (B)

Flaps have a defined maximum operating speed, called V_FE, for each flap setting. For Flaps 1, the airplane’s limit is 250 knots, so you should not exceed 250 knots indicated airspeed with Flaps 1 extended. This limit exists because extending the flaps increases wing surface and lift while also adding drag and different loading on the wing and flap mechanisms; going faster than the limit can overstress the flaps or cause control issues. In practice, you accelerate with Flaps 1 up to a safe speed, then retract as appropriate, keeping below 250 knots while Flaps 1 remains extended. The other numbers would pertain to different flap settings or aircraft-specific limits, not the Flaps 1 limit.
