In school we had our MEL pages (how many are installed vs how many required to fly), but we never really discussed the ins and outs of how it works. Earlier this week I had an interview and an MEL scenario came up and I really stumbled through it, so my question is- in actual dispatching what happens? What is the sequence of events? Maintenance calls you with a parts issue and then you look it up in your MEL and see if the aircraft can still operate? Is that it? Does the pilot ever call? Sorry for my ignorance on this topic. Just trying to learn.
