1. A method for determining an ability of an aircraft to reach a performance goal during a flight, the method comprising:
- identifying, using a model of the aircraft and flight state data, a current performance of the aircraft during operation of the aircraft, such that the current performance comprises a current;
lift, thrust, and drag, of the aircraft in flight;
identifying a current flight envelope of the aircraft based upon a performance monitor comparing the current performance of the aircraft to a predicted performance for the aircraft based upon a baseline design for the aircraft, thus deriving delta performance factors and correcting an aerodynamic and engine database generating a next predicted aircraft performance input to the model;
the performance monitor applying limits, based upon a desired state, onto the current flight envelope; and
the aircraft performing an operation based on the current flight envelope of the aircraft.

Abstract
A method and apparatus for monitoring an aircraft. A current performance of the aircraft is identified during operation of the aircraft using a model of the aircraft and flight state data. A current capability of the aircraft is identified from the current performance of the aircraft. An operation is performed based on the current capability of the aircraft.
