SYNOPSIS

A flight data monitoring (FDM) programme involves regularly downloading and

analysing data recorded from an airlines operations. The primary purpose of this

analysis is to improve the safety of the airlines operations by identifying and

rectifying adverse trends in the flight operations.

It is not mandatory for an airline to run an FDM programme, with the exception

of airlines in China and France. However, the number of carriers with such a

programme is increasing as more airlines recognise the safety benefits that can

arise from regularly monitoring flight data. It is likely that more countries will

make FDM programmes mandatory in the coming years. As well as the safety

benefits, there are a range of other benefits which an airline with an FDM programme

can enjoy. Some of these will reduce the costs incurred by the airline and these cost

savings are likely to be more than sufficient to cover the costs of running the FDM

programme.

This work describes the elements that make up an FDM programme, outlines

what the costs are to run such a programme and describes the range of benefits

available. These benefits are quantified with data taken from airlines that have

established FDM programmes. It is likely that as airlines become more mature in the

use of their FDM programmes they will exploit more of these benefits and identify

new ones, while at the same time improving the safety of their operations.
