Planned hours show the funded annual flying task for each aircraft type as agreed in annually agreed customer supplier agreements (CSA) between the Front Line Commands and Defence Equipment and Support. Actual hours flown includes both those flown in the UK for training as well as those deployed on operations. Hours flown in excess of the CSA on operations are funded by the Conflict Prevention Fund.
There is no requirement to hold data on average flying hours. CSA calculations are based on the total amount of flying hours that can be supported by the integrated project teams for a given aircraft type and are not broken down by individual airframe.
