A method for calculating vertical trajectory values is provided. The method obtains aircraft performance data for a particular aircraft and atmospheric condition data associated with an air route; calculates a cost-efficient vertical trajectory for the air route, based on the aircraft performance data and the atmospheric condition data, wherein the cost-efficient vertical trajectory comprises a plurality of altitude values for minimizing cost for the particular aircraft during travel of the air route; obtains an altitude consistency threshold; and adjusts the cost-efficient vertical trajectory using the altitude consistency parameter, to create an optimized vertical trajectory for the aircraft route.

Methods and apparatus for global optimization of vertical trajectory for an air route

A method for generating a request onboard an aircraft, by a processor communicatively coupled to system memory and a communication device, is provided. In response to a requested change to a current flight plan, the method automatically generates, by the processor, a text-based clearance request for the requested change, the text-based clearance request comprising aircraft identification and the requested change, and the requested change comprising at least one of a new cruising level, a new cruising speed at the new cruising level, flight rules, a new route description, and revised time estimates associated with waypoints of the current flight plan; and transmits the text-based clearance request, via the communication device.
