Abstract: A method for calculating a fuel consumption differential corresponding to an aircraft changing from an original trajectory (which incorporates the cost model of the airline through speed and altitude parameters within the flight plan) to a revised trajectory, the method including (1) calculating a first total excess energy associated with flying the aircraft at the original trajectory beginning at an execution time, the first total excess energy including excess energy due to climb and excess energy due to deviation of the original trajectory from an efficiency curve of the aircraft; (2) calculating a second total excess energy associated with flying the aircraft at the revised trajectory beginning at the execution time, the second total excess energy including excess energy due to climb and excess energy due to deviation of the revised trajectory from the efficiency curve; (3) comparing the first and second total excess energies to obtain a total excess energy differential; and (4) calculating the fuel consu

Abstract: A diagnostic system and method are provided that include an interface for receiving input relating to observed symptoms indicative of one or more failed components, a processing element for correlating the input relating to the observed symptoms with at least one suspect component that is capable of causing the observed symptoms upon failure, and a display for presenting information relating to the suspect components. The processing element correlates the input relating to the observed symptoms with the suspect components in accordance with a diagnostic model constructed based upon systemic information, experiential information and factual information. The processing element generally presents the suspect components in a listing prioritized based upon the relative likelihood that the respective suspect components caused the observed symptoms.

Abstract: A system for providing an aircraft pilot and/or autothrottle and go-around pitch axis control with information when a go-around should be initiated during an approach in response to either a hazardous flight status of the aircraft or to wind shear encounter by the aircraft. The present system utilizes a gain schedule control law based on the bug speed set by the pilot and on pilot go-around criteria to trigger a go-around signal for the pilot and/or the automatic control systems.
