An exit taxiway is to be designed for a supersonic aircraft with turn off speed of 90 km/hr. The turning radius of exit taxiway based on Horonieff equation using the following data will be

Coefficient of lateral fraction = 0.11

Wheelbase = 18 m

Tread by main landing gear = 7 m

The width of taxiway = 22.5 m

Oleo strut of landing gear = 6 m.
