I m surprised you weren t aware of what dispatch reliability is A google search reveals it s definition and central importance in operating and marketing airliners In the military I would guess schedules and operating economics would be of relatively little importance in comparison to the airline industry so it wouldn t be much of a concern An easily understandable definition of what dispatch reliability is is given in the article for those not aware Nonetheless I have added a suitable reference explaining in more detail dispatch reliability and related terms the 737 article is not suitable as a reference that was given just as an example of the use of the term by Boeing The wholesale reverts were intentional not sure what you mean there
