Many thanks safetypee; indeed the debate is going on about the type of approach. The 'airfield approach' might well be a better way to go here, and I shall facilitate the thought with the flying ops people. Along with the tailwind options, EGPWS, etc.
One minor side-track is a new thought this week that there must be a PAPI installed at a 7 degree glideslope so as to facilitate the approach. The PAPI design can be done for that glideslope from fundamental principles, but actually mounting the baseplate on the ground so it can be adjusted to give a 7 degree angle is less easy. The original thought was that the runway is not a precision approach runway, and a PAPI is just not needed. Still not got the answer on that on, and if anyone has ideas, I'd also appreciate those.
Make one minor change from the normal operation, and many other changes follow faithfully along, close behind, each juggling a piece of swiss cheese in the air, trying to line up the holes. . . .
