Helicopter Coordinated Turn Calculator
Description
This calculator estimates the Glevel \( N_z \),
turn radius \( R \),
and yaw rate \( r \) from a helicopter's
speed \( v \) and
bank angle \( \phi \)
in a coordinated turn.
Equations
The following equations are used to estimate the values.
\[ N_z = 1/\cos\phi \]
\[ R = \frac{v^2}{G\tan\phi} \]
\[ r = \frac{v}{R} \]
For more details including the derivation of these equations see
our article on coordinated turns.
