This App calculates the flight turn radius, in still air, for an airplane.

This App allows for the estimation of the flight turn radius of an airplane, in metres, taking into account:
-the bank angle;
-the aircraft stall speed;
-the safety speed factor - sets a margin above the stall speed;
-the density altitude (altitude, QNH and temperature).

The calculations are valid for coordinated level turns in still air (no wind).
The calculations do not account for the finite rate-of-bank (roll-in and roll-out).

This App is for ground training only. It is NOT suitable for flight planning.
