How does load factor (G-loading) in a coordinated turn affect stall speed?

Choices

• Stall speed is independent of load factor.

  Load factor is the dominant variable in maneuvering stall speed.

• ✓ Stall speed increases with the square root of the load factor.correct

  Stall speed rises with the square root of the load factor, so a 60° banked level turn (2 G) increases stall speed by ~41%. In a level turn, lift must equal weight × load factor. Stall speed scales as √(load factor): at 2 G (60° bank) stall speed is √2 ≈ 1.41× the 1 G value. This is why "accelerated stalls" in steep turns occur at airspeeds well above book Vs.

• Stall speed decreases as bank angle increases.

  Reversed — stall speed increases with bank in a level turn.

• Stall speed only changes when flaps are extended.

  Flap extension changes stall speed, but load factor is the answer to the question asked.
