Definition#
Bank angle is the angle between the aircraft's wings and the horizontal plane. In a coordinated turn, the bank angle determines the turn rate and the load factor experienced by the aircraft.
Why It Matters Operationally#
Steeper bank angles produce tighter turns but higher load factors. At 60° of bank, load factor is 2G and stall speed increases by 41%. Transport category aircraft typically limit bank to 25°–30° in normal operations.
