Monitoring and scheduling fuel use for multi-fuel aircraft powerplants

A method, comprising:

• processing first fuel data to determine a first trend of powerplant deterioration for a first fuel, wherein the first fuel data is indicative of a plurality of first values of a tracked operational parameter for a fleet of aircraft with aircraft powerplants of a common aircraft powerplant model, and the plurality of first values were recorded when running the aircraft powerplants on the first fuel;
• processing second fuel data to determine a second trend of the powerplant deterioration for a second fuel different than the first fuel, wherein the second fuel data is indicative of a plurality of second values of the tracked operational parameter for the fleet of the aircraft with the aircraft powerplants of the common aircraft powerplant model, and the plurality of second values were recorded when running the aircraft powerplants on the second fuel;
• and
• scheduling use of the first fuel and the second fuel based on the first trend of the powerplant deterioration and the second trend of the powerplant deterioration to increase time on wing for an aircraft powerplant of the common aircraft powerplant model.
