Flaps 8 to Flaps 1 Speed is which of the following?

• A. V2 + 12
• B. V2 + 20
• C. V1
• D. VT - 15

Answer: (A)

Flap transitions are done at a defined transition speed that keeps the aircraft safely above stall while you reduce flap extension. For moving from Flaps 8 to Flaps 1, the recommended speed is V2 plus 12 knots. This adds a comfortable margin above the minimum takeoff safety speed, ensuring you maintain good climb performance and control as you retract flaps. Too little margin (like V2 itself) could risk a stall if the airplane slows during the maneuver, while too much margin (like V2 plus 20) would unnecessarily slow the climb and delay flap retraction. V1 is the decision speed for aborting or continuing a takeoff, not a flap transition speed, and VT minus 15 would place you well into a stall-prone regime—not appropriate for flap retraction.
