Roland,
Yes I agree that this issue by itself is trivial - although I don't know why anyone wouldn't be in favour of crediting pilots with experience that the vast majority of aviation regards as perfectly legitimate. I simply feel that it highlights the whole issue of us retaining our parochial practices.
Instrument minima, RT, altimeter setting procedures, fire and rescue cover etc are all areas where we do things differently. I am not suggesting that there is no legitimacy to the differences, it's just that they all add up to make it more awkward for others to operate with us and for our people to adjust accordingly whenever they go elsewhere.
I accept that the "change for change's sake" argument has validity but it does depend on your perspective. Rationalizing RT to match CAP413 might seem an unnecessary burden to QFIs at training bases but it would have direct benefits in improving interoperability/deployability for the front-line. As an example - do we really need to be reminded to perform checklists by ATC? They won't do it in sandy places.
