SAS old boy godspeed and fair winds and all that on your well-deserved retirement gig navigating a boat around exotic, palm-lined islands; I'm more than a little envious. Your experience and knowledge are beyond reproach and have served you well during a long, accident free career -as you pointed out. Your expertise on everything from Altimeters to Zulu Time is much valued by all here on Pprune. You are truly one of the Wise Old Men of this board.
But when it comes to the inner workings of PHI your firsthand experience is nada, zilch, zero.
