Mr Buzzy.
Sorry I havent been around to reply but one must work for a living.
Now lets get one thing straight here son.
When a very very senior Check and Training Captain (that could possibly decide the degree of competence of your friend) says blatantly that both you and your mate is incorrect, who am I to question his professionalism?
No Mr Buzzy, as a professional aviator I will not enter into diatribe and petty arguments when you clearly have neither experience nor little knowledge on the subject at hand.
It is also clear that your mate has not amended his manuals, especially when you quoted inacurrate manual references from an unamended manual.
Just stick to listening to your scanner and playing Flight Sim 2004 Mr Buzzy.
Who knows pal, you just may actually learn something from those twits that did the programming!
No apology is required or will be forthcoming Mr Buzzy.
