Chaps, it would be far better to stick to discussing the question and what our experiences of it are. There has been a dreadful trend in Pprune later of analysing everything down to the minutest detail to find opposite meanings and prove any answer, even my 'black is black- no it's not, it can be white!' remark, is incorrect in certain circumstances! Look at the icing question, and how my answer from Boeing manuals is dissected and torn apart! There trend is growing to personally attack and insult posters rather than play the ball.
All it is going to take us to is people who know refusing to get involved in answering queries because they know someone will try and demolish them. Let's just play the question, not the player.
