1. A method, comprising:
obtaining data associated with a route of an aircraft;
applying a filter to the data to reduce noise;
detecting an event from a pattern in the data;
calibrating a performance model associated with the aircraft by:
determining a plurality of estimated coefficients;
determining a modeled fuel flow using the performance model and the plurality of estimated coefficients;
comparing the modeled fuel flow with an actual fuel flow associated with the data; and
determining a plurality of adjusted coefficients based on the comparison between the modeled fuel flow and the actual fuel flow;
determining a first cost index associated with the route based at least in part on a segment of the data associated with the event, wherein the first cost index is determined using the performance model and the plurality of adjusted coefficients;
comparing the first cost index to a second cost index associated with a plan for the route, wherein the second cost index is used to determine the plan;
determining a cost penalty associated with the route based at least in part on the comparison between the first cost index and the second cost index; and
performing one or more actions associated with the aircraft in response to determining the cost penalty.
