An aircraft executes a horizontal loop at a speed of 720 km/h with its wings banked at 15°. What is the radius of the loop?

720 km/h = 720 x (5/18) = 200 m/s is the speed of the aeroplane doing the horizontal loop.

The banking angle is 15 degrees.

We have tan= v2/rg.

(200 x 200)/(10 x tan 150) = (200 x 200)/ (10 x 0.2679)= 14931 m
