Regional Fatigue Environment Study for Commuter Airlines

A fatigue meter data acquisition and processing program has been set up to take advantage of the operational nature of commuter airlines, with the purpose of defining the fatigue life of an aircraft on an individual airline basis.

Commuter airlines operate in a confined geographical area with its particular weather and turbulence characteristics.

The result was that in most cases, a substantial increase in the aircraft's fatigue life could be justified in comparison with the one estimated by using a unified turbulence model, which was conservatively established from V-G/VGH recordings from aircraft flying all over the country.
