OldGrubber,
I second that RE: RPW. Due to a back problem I had to utilise the RPW in the last few years of my service and have never experienced any problems at VL. I also concur that the Naval PTI's are very good. I have only witnessed one failure and that was at SULTAN.
What did confuse me last year was the differences between RN and RAF requirements for the beep test at St Mawgan. It was advantageous to be in the dark blue it appeared! Why are the required standards so different?
Regards
SJ
