I think there is scope for more experienced flying instructors to make a career out of it, but the circumstances need to be right. Like everything, it’s too simplistic to think of the lack of (experienced) flying instructors in the UK (and worldwide actually) as a pay issue, although it generally tends to be placed as front and centre of any discussion of this nature. If the instructing is almost always weekends, bank holidays, evenings etc then it just is not compatible with any sort of life (stand fast the hermits amongst us).
There are plenty of ex-mil rotary instructors and I dare say, rotary re-treads coming out of O&G, HEMS, VIP, who would at least entertain the thought of going into a valued instruction job but, as I said at the very beginning, the circumstances have to be right. Issues such as: 1. What is the working routine, 2. who are we going to teach, 3. is it just instructing or will there be CAT jobs on top, 4. is it commutable (linking back into 1), 5. What is the working environment like etc
Most aviation jobs are on a rotation basis, so why not instructing? Make it attractive- how about a 4 on, 4 off rotation that is commutable, teaching career students with a reasonable salary? I think once we as an industry start to think on these terms when it comes to teaching and instructing, then we will attract quality, experienced individuals. If we are thinking of going after hour-builders (who are in their own right, motivated, dedicated and high-quality individuals to have got that far) then we will just go round in circles. Just my 10p.
