Question : 30
Total: 40
An aircraft executes a horizontal loop at a speed of 720 km h1 with its wings banked at 15°. What is the radius of the loop?
Solution:  
Speed of aircraft, v=720km h1
=720×
5
18
=200m s1

angle of banking, θ=15°, radius of the loop =r=?
tanθ=
v2
rg
or r=
v2
gtanθ

=
(200)2
10×tan15°

=
40000
10×0.2679

=14.9×103m=15km
