And 1.1
Firtst find out the angular velocity of the aircraft.
Angular velocity(omega)= V(TAS)/r(radius)
Take proper units . You will get omega in radians/sec.
Now convert that into degrees//sec and you will get 3deg/sec.
That means rate one turn. So find angle of bank by 10%TAS+7.
Now load factor= 1/cos(angle of bank)
L=1.1
