After two or three years of use, an aircraft's actual fuel consumption generally deviates from the manufacturer's data for the respective model. Therefore, when calculating the amount of fuel needed, airlines use a correction factor which expresses the difference between the actual data and the reference data. This factor can either be uniformly set for an airline's entire fleet based on the manufacturer's performance data or determined individually for each aircraft with the help of a performance solution.
Lido electronic Airplane Performance Monitoring (Lido eAPM) is the first Web-based tool on the market which allows airlines to evaluate the current consumption and performance data of each aircraft in their fleet.
