To ask the Secretary of State for Defence what the (a) inflow and (b) outflow rate was of RAF pilot crew for each aircraft type in the most recent period for which figures are available. (279957)

Intakes are Into Productive Service flows, personnel flowing from untrained to trained strength.

Outflows are of all pilots, including ranks of Wing Commander and above who are classified as belonging to the General Duties branch, and therefore not all will be flying aircraft when they leave the service.
