Notes:

1. These figures are accurate as at 19 July 2017.
2. The MOD does not track data on the number of aircrew who will complete their basic flying training outside the UK, at organisations such as the NATO Flying Training in Canada and Euro-NATO Joint Jet Pilot Training Programme in the US because, currently, no aircrew complete their basic flying training outside of the UK.

You can find further information on the training of aircrew here.
