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?
Speed of the aircraft, v = 720 km/h = 720 x 5/18 =200 m/s
Acceleration due to gravity, g = 10 m/s2
Angle of banking, θ = 15°
For radius r, of the loop, we have the relation:
tanθ = v2 / rg
r = v2 / gtanθ
= 200 x 200 / 10 tan15
= 4000 / 0.268
= 14925.37 m
= 14.92 km
