Abstract: A system and a method include a control unit configured to determine drag factors and fuel flow factors for different phases of one or more prior flights of an aircraft, and determine a fuel level for one or more upcoming flights of the aircraft based on the drag factors and the fuel flow factors for the different phases of the one or more prior flights of the aircraft.

Abstract: A method for automatic generation of integration tests from unit tests includes automatically running, by a processor, a unit test for each model of a plurality of models making-up a system. The method also includes automatically determining, by the processor, integration of unit test cases of interfacing models for one or more groups of interfacing models of the plurality of models. The method additionally includes automatically running, by the processor, an integration test for each group of interfacing models using the unit tests for each model of the interfacing models. The method further includes automatically detecting, by the processor, at least one of inconsistent, incomplete or incorrect data transmitted between the interfacing models for each group of interfacing models.

Abstract: A method and electronic device for providing an optimal quantity of aircraft fuel. The method comprises collecting recorded flight data from past flights of an aircraft; determining aircraft specific performance correction parameters per flight phase, using the recorded flight data; collecting a flight plan of the aircraft; determining the total fuel required for the given flight plan, using the aircraft specific performance correction parameters; determining a single synthetic drag factor (?DFMS) and a single synthetic fuel factor (?FFFMS) that, when used by the aircraft FMS, yield the said total fuel required for the given flight plan; receiving an estimated total fuel required determined by the aircraft FMS based on the flight plan, the single synthetic drag factor (?DFMS) and the single synthetic fuel factor (?FFFMS). The method allows reducing the fuel weight and total flight cost, and is particularly advantageous for FMS which only admit one single drag factor and one single fuel factor.

Abstract: Example methods and apparatus are described herein for establishing optimized holding patterns for aircraft. An example method includes generating, based on a cost function condition, a cost function with at least one holding pattern optimization parameter, applying an optimization routine to the cost function based on optimization conditions to obtain a value for the at least one holding pattern optimization parameter having a minimized cost, and obtaining an optimized holding pattern with the selected value for the at least one holding pattern optimization parameter.

Abstract: A method and electronic device for optimizing a flight trajectory of an aircraft subject to time of arrival control constraints. The electronic device comprises a communications unit, an optimization module, and an alert generation module. The communications unit receives atmospheric conditions about an aircraft route, aircraft operational constraints and real-time aircraft state and performance. The optimization module receives time of arrival control constraints for the aircraft route and flight trajectory optimization parameters at least including flight cruise altitude. The optimization module comprises a flight trajectory generator that generates sets of values for flight trajectory optimization parameters, computes flight trajectories of the aircraft and selects, based on optimization criteria (e.g. fuel saving, speed control margin), one optimal flight cruise altitude with a computed flight trajectory complying with the time of arrival control constraints.

Abstract: Systems and methods for generating arrival traffic schedules incorporating equipage-dependent in-trail spacing (time or distance). An arrival management system has a ground-based scheduling tool that applies customized spacing buffers between in-trail aircraft depending on the types of FMS equipage onboard aircraft sequence pairs.
