John_T,
Ummm, I'm taking a punt on a PM not being necessary when there's only good things to say of people, and it doesn't compromise their anonymity.
P_T, as you correctly figured = Peter E. Turner, a true gentleman and a master of his craft. His parent's must have had a hint of his future when they gave him the initials P.E. Like yourself, I too have a large learning debt to him, along with a good number of my ex colleagues from the old firm. He did indeed retire to Toowoomba, I've been in touch several times over the years, and his answer to the occasional performance question is "I've forgotten all that stuff. I'm a gentleman farmer now". I don't know how good he is as a farmer, but a true gentleman he was, and is. The family legacy lives on, son Mike was a MD-11 captain the last I heard.
G_S = Gordon Stiles (or was it Styles) of British Aerospace. Another fine gentleman to whom I have a learning debt. I never did get to know him personally, only professionally. I listened well in his presence, he had a long and large career in Performance Engineering, including work on such minor types as
THE Concorde.
J_T = Another fine gentleman, who exists in cyber land for most, not such a bad chap at all when you get to know him, just don't get him started on directional control problems at Vmcg
(Relax, I'm a convert)
Whether it was John or Peter who changed allegiances eludes me, I know that it is true for one of them, my money is on John's having done so.
i.e. the Field Limit and the Obstacle Limit are equal.. need that be so - You're right again of course, they need not. I must admit that it was a tongue in cheek attempt to bring the very balanced
Mutt into the debate with a bit of "Balanced Field / Obstacle" takeoff verbiage. (That's my excuse for the day anyway).
Regards,
Old Smokey
