Although the discussion has moved on slightly, (I'm a bit late in reading the thread) a document that may be more readily available to many of us with all the relevant info on revals. etc. than the JAROPS verbiage, is GID 33. Latest edition is verson 5 issued 9 Nov 2001.
Under part 2 Revalidating an aircraft rating it states in BOLD type that to revalidate a SEP rating on experience there must be a SINGLE flight of at least one hour with a suitably qualified instructor. I have to agree that it does seem ridiculous that officially, the training flight could not be done to another aerodrome for a full stop landing (and refreshment) with all that could be gained from that sorie with an instructor. Much more informative overall than flying around for an hour, I'd have thought.
