I don't think RAF airfields actually have taxiway designations, so I don't think you will be very successful in your search. In my 16 years in the RAF it was usually ""Taxy to holding point runway 27, call before crossing threshold runway 02." Something like that, anyway. You looked at your aerodrome chart and got on with it, because there was usually only one way to go - RAF airfields, in the main, had a wartime heritage and the layouts are pretty self explanatory, and similar. If you were new to a particular airfield, and unsure of a taxy route, you just asked!
