Couldn't find it in quick search... 5 years (academy) + 2 (flight school) = 7 owed, after receiving wings. Is this correct? Heard it might be 5 + 4 = 9 (again after wings). Is it the same for Marine Corps aviation? If there's a wait to get into flight school does that time count towards the 5 owed for the academy? What about time at TBS?
