Abstract: Systems and methods for battery-based aircraft performance are provided. An example computer-implemented method includes accessing, by a computing system, flight plan data for a first flight. Based on the flight plan data, the computing system can compute a first expected power demand on the aircraft's battery system for the first flight. The computing system can access initial battery state data of the aircraft. The computing system can compute, using a battery model, a first capability output based the first expected power demand and the initial battery state. The first capability output can be indicative of a range/ToF of the aircraft for the first flight. The computing system can determine an ability of the aircraft to perform the first flight based on the first capability output and generate an itinerary accordingly. The computing system can transmit, over a network, instructions associated with implementing the itinerary for performance by the aircraft.
