Thanks for the Hansard link Sky9. Impressed and surprised that some sense is talked in parliament. (Not by Mr Osborne)
You can pretty well stay with most of the SIDs if you use raw data and anticipate the turns by a couple of tenths of a mile and go round the turn with take off flap. It does make for a pretty high workload at a time when the workload is pretty high anyway. Hardly surprising that a few of us get it wrong occasionally.
