Recommendation 1 d. of this report states:
The supervisory measures for aircrew that (sic) fly multiple ac types are reviewed, including General Aviation.
This is an utter red herring. They may as well 'recommend' that you don't drive a car or ride a bicycle if you have to fly a fast jet. Many RAF aircrew fly both Brenda-jets and light aeroplanes with no difficulty whatsoever in switching brain cells between the disciplines. Along with many others, I've gone straight from instructing on the VC10 to instructing in a Cherokee on the same day - there really is no problem. The only occasion when flying light aircraft should
perhaps be avoided is when the pilot is undergoing military helicopter flying training - although I don't actually subscribe to this view personally.
The real issue is the scandalously low allocation of flying hours to each fast-jet pilot per month. This horse$hit about the effect light aircraft flying might or might not have played in this fatal accident is smoke and mirrors and is complete and utter bolleaux.
