Work out turn radius of aircraft instantly with clear inputs, formula shown and shareable results.
In a coordinated level turn the horizontal component of lift supplies the centripetal force, giving radius equal to velocity squared divided by g times the tangent of the bank angle. Radius grows with the square of speed, which is why a fast aircraft needs far more airspace for the same bank angle.
Turn radius
r = V^2 / (g x tan(bank)), V in m/s; rate of turn = V / r
Aviation results are planning estimates only. Always verify take-off, landing, fuel, weight and balance figures against the certified Aircraft Flight Manual, current performance charts and applicable aviation regulations before flight.
Radius depends on V squared. At twice the speed the aircraft needs four times the turning circle at the same bank angle.
No. The equation contains no mass term, so a light aircraft and a heavy one at the same speed and bank angle fly the same radius.
