The decision height for assessing whether an aircraft met Wave Air’s stabilised approach criteria was too low.
The operator’s action to raise the stabilised approach decision height significantly increases the time available to reduce excess airspeed and the distance from the ground/obstacles during a go-around.
Wave Air modified its operations manual to require that stabilised approach criteria were to be met by 300 ft above airport elevation in visual meteorological conditions and 500 ft when operating under the instrument flight rules.
