Arrow Aircraft Performance Monitoring

Aircraft performance monitoring is a procedure devoted to gathering aircraft data in order to determine the actual performance level of each airplane of the fleet with respect to the manufacturer’s book level. The aircraft performance book level is established by the aircraft manufacturer and represents a fleet average of brand new airframe and engines. This level is established in advance of production. Normal scatter of brand new aircraft leads to individual performance above and below the book value. The performance data given in the Flight Crew Operating Manual reflects this book value.

The performance levels are measured in their variations over time. Resulting trends can be made available to the operators’ various departments, which perform corrective actions to keep a satisfactory aircraft condition. Today’s aeronautics industry has been undeniably dominated by generation and acquisition of large amounts of data in all airline departments. In particular, airline flight operations have been staggering under a high flow of data. The key point in this massive data flow is to identify what is needed and for what purpose.

This booklet has a five-field purpose. First, it will introduce performance monitoring, presenting the different analysis methods and tools. Second, as a consequence of the amount of data required for analysis, the most common ways to get data routinely recorded are detailed, through a quick overview of the available aircraft systems. Third, it will give some guidelines on the way to process the data. The fourth part will help assessing data coming from regular cruise performance analysis. Finally, it will give Airbus recommendations on the way to use the results the analysis in daily aircraft operations.
