MONITORING FOR UNSTABLE APPROACH OF AIRCRAFT USING SPECIFIC ENERGY

The present disclosure provides a method of monitoring for an unstable approach of an aircraft during flight in one aspect, the method including: determining, using values of a ground speed and a height of the aircraft derived from measurements acquired during the flight, a specific energy of the aircraft during an approach phase of the flight. The method further includes determining a reference specific energy of the aircraft, defining an energy range relative to the reference specific energy, and visually displaying, using a first flight instrument of the aircraft, an indicator of the specific energy relative to the energy range.
