Introducing Flight Data Monitoring  

Flight Data Monitoring is known variously as FDM, FOQA, MOQA (Military), GDRAS, HOMP and several other names. The idea is the same - FDM / FOQA is a quality assurance tool and the thing being measured is the aircraft and how it is flown. Statistics should then drive a continuous improvement process

The table below gives an idea of the processes involved and compares it to a manufacturing process. 

Process Manufacturer Airline
Recording measurements Either testing the product or measuring it FDR or QAR records values that are downloaded
Analysing measurements Determining whether the product is within tolerance or working correctly and can be shipped Analysing the flight data to determine whether there have been operational or mechanical values that are outside safe or economical limits.
Reviewing problems Examining samples to determine extent of problem Viewing flight data to check analysis
Investigate causes of problems Do something to find out why the problem with that sample occurred Investigate a flight data in more detail to find causes of problems
Implement actions Implement and record corrective actions Implement and record corrective actions
Audit actions See whether the action was completed See whether the action was completed
Review Statistics Determine waste Trend flight data to find developing trends or long term problems
Implement and record corrective actions Decide on processes changes and make changes decide on suitable technique(s) to make changes (email, newsletter, training etc) to inform educate and train and record
Review (audit) effect of corrective actions Review whether actions have the desired effect and make more changes if necessary. Review whether actions have the desired effect and make more changes if necessary.

This is a continuous improvement process.

Without corrective actions you will not
improve safety or economy

Aerobytes' FDM / FOQA software is the only FDM / FOQA software to allow users to record their actions, display them over the statistics and close the quality assurance loop.

The UK/CAA has produced an excellent guide on the practicalities of FDM.  This can be downloaded using our links and downloads page.
