This makes a number of assumptions, like everyone making it to age 65 with no retirements. Looks like somebody has done a lot of leg work. Some hard numbers on retirement forecasts for the next decade or so. Now if somebody could post a comparison that showed the forecast amount of military/regional/forecasted ATP qualified aviators, etc, in the same time period that would be fantastic. Don't ask me for questions or validity of the data, if you seek clarification or find some major disparity with the numbers contact the author via the contact info at the bottom of their website.
Where to find 24,223 qualified pilots in the next decade?
