Method of determining a comparison of an aircraft's performance capabilities with performance requirements

摘要

A method for providing an indication of the capability of an aircraft to dissipate altitude ( 20 ) and speed ( 12 ) in comparison with descent and deceleration requirements necessary to establish stabilized flight conditions prior to landing on a runway. By referencing a shortest flyable path to a target point ( 10 ) and subsequently to the runway, the present invention provides a method to evaluate energy state, independent of any predetermined flight path. Tangible scaling ( 16 ) of output values provides an indication of the effects of subsequent maneuvering and deployment of aircraft devices in usable terms that can be directly applied without further interpretation or conversion.
