## GM1 HPT-DSN.D.300 Helicopter stands

(a) It is not considered good practice to locate helicopter stands under a flight path.

(b) Where non-simultaneous operations are envisaged, the protection areas of helicopter stands and their associated taxi-routes may overlap (see Figure GM1-D-1).

(c) Characteristics: For a [helicopter stand](https://avioverse.aero/glossary/easa/helicopter-stand) intended to be used by wheeled helicopters for turning on the ground, the dimension of the helicopter stand and the [protection area](https://avioverse.aero/glossary/easa/protection-area), including the dimension of the central zone, would need to be significantly increased.
