A re-think
Rather than start major mods on the Tutor why not look at an alternative?
There are many civilian flying training organisations spread across the country. All are required to have a CAA audit into their training systems and facilities.
Why doesn't the ACO look at these pre-audited schools and see if they might fill the needs for cadet AEF? An aircraft like the PA28 could take two, possibly three cadets (depending on their mass) and fly them for an hour or so for a reasonable rate. Spreading the load across a larger number of FTO's around the country might mean that at least some of the cadets do actually get to fly during their ACO service.
I made this suggestion to my Wing Commander back in February. This was passed up the ling to OC 2FTS. Thus far I've hod no acknowledgement that they have even received the note.......
