Anybody Referencing the MEL in Flight
Some seem to like to call it a dispatch document only and of no use once airborne. I certainly think it can have some useful information. But little can be found about this.
But I did read this in an accident report today..."Although the MEL is intended to be used prior to the flight to dispatch an aircraft in operation, its associated procedures may be used as a guide or guidance on the conduct to be held by the Navigating Flight Personnel, should system or functionality failures be identified in flight, particularly in the absence of a specific procedure to be applied in flight. , as is the case with the GPWS."
