bank angle for a specific speed
Hi, could anyone tell me the equation for working the bank angle, if speed is given and for a rate 1 turn.
the question is:
An a/c is travelling at 120kts, what angle of bank would be required for a rate one turn?
a) 30 degrees
b) 12 degrees
c) 18 degrees
d) 35 degrees
the answer is 18 degrees, but i cant for the life of me work out how they got the answer.
thanks for your help, CJH
