OK, so lets look at 2 other scenarios -
No 1
If the STAR quotes a planning point of level xxx by yyy, how come we then get another be level by issued over the radio. Example MIRSI 1B arrival into MAN. Plate says expect FL200, 30 before WAL (or something like that) Now you leave DUB and get transferred to London who say be level at FL 240, 70 before WAL - that is nowhere on the plate and just confuses the hell out of me - why can't they stick with the planning advice on the plate ?
No 2
As we climb out of MAN on a HON departure, MAN say no speed control, hand us to London who say be FL310, 50 before MID. Like in your dreams mate in an Airbus - we would have to fire the bottles and get rows 20 through 30 to have a s#*t to achieve that one. Why can't you ask the operators what the aeroplane can achieve under normal conditions before expecting extraordinary rates of climb.
Boeing pilots need not comment on this thread - OK ! That includes you Mr L
