Wino,
I will try not to get too technical
Thank god you didn't get too technical!! It seemed completely clear to me after I dusted off my Perf 'A' notes and got out my copy of 'Flying the big jets'. Good explanation, but your 'simple' explanation perhaps explains why the subject is not easily understood even by some pilots that operate Perf A aircraft.
Back to the thread, I heard a rumour that appeals are in the offing over the sackings.
