A light aircraft flying straight and level has a stall speed of 100 kts. It banks to an angle of 30°. Calculate the load factor and stall speed in this turn:
  • A
    Load factor = 1.15; Stall speed = 107 kts.
  • B
    Load factor = 1.07; Stall speed = 115 kts.
  • C
    Load factor = 1.07; Stall speed = 107 kts.
  • D
    Load factor = 1.15; Stall speed = 115 kts.

In a turn, the load factor (n) is equal to:

n = 1/cos(ø), where ø is the bank angle.

n = 1/cos(30º) = 1.15

The Stall Speed in the turn (VSNEW) is calculated by:

VSNEW = √n x VSOLD

VSOLD = 100kt

VSNEW = √1.15 x 100 = 107 kt
