You require the bank angle to be able to work out the load factor because in a turn the load factor = 1/ Cos bank angle

The formula for bank angle is Tan bank angle = TAS squared / g x radius

You have to convert the TAS into SI units so 200 x 0.515 = 103 m/s

103 squared / 10 x 2000 = 0.53045

That is the tan value so the bank angle is 27.94371º We know “n” = 1 ÷ Cos bank angle, so “n” = 1.1319792
