Hi there
Those NATO flight times of which you speak, tend to refer to fast-jet hours only.A lot of air forces keep smaller aircraft for their pilots to maintain proficiency, when the fast stuff is unavailable.I remember reading somewhere that a pilot with "only" 140 hrs/yr on a fast-jet was regarded as not front-line ready....An Air Corps pilot could fly as little as a couple of hundred or as much as 5-600 hrs per, depending on his aircraft type and his posting, especially if he has a busy ground duty or is posted out on a course.More than once, AC pilots have had their ratings lapse as a result of ground duties or other events and have to be rerated all over again. Anyhow, their schedule is completely unlike a civil roster, so there is no guarantee any flight may happen on any given day.
