Systems and methods for tail-specific parameter computation

A method comprising:

• receiving, by a device, flight data during a flight of a first aircraft;
• generating, based at least in part on the flight data and a tail-specific aircraft performance model for the first aircraft, a recommended cost index and a recommended cruise altitude;
• providing the recommended cost index and the recommended cruise altitude for the flight from the device to a display device of the first aircraft;
• receiving a user input indicating a selected cost index;
• and
• generating, based on the selected cost index, a control command to update an altitude, a speed, or both, of the first aircraft.

A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to:

• receive flight data during a flight of a first aircraft;
• generate, based at least in part on the flight data and a tail-specific aircraft performance model for the first aircraft, a recommended cost index and a recommended cruise altitude;
• provide the recommended cost index and the recommended cruise altitude for the flight to a display device of the first aircraft;
• receive a user input indicating a selected cost index;
• and
• generate, based on the selected cost index, a control command to update an altitude, a speed, or both, of the first aircraft.
