In that case, expect the 'definitive' answer some time post 2015.

SixDelta, sorry if I ruffled your feathers. I don't think you'll find a definitive answer, even SRG will give you an interpretation (although it may be true thay have the power to enforce their will) but that will only apply to UK Civil airports (i.e. the minority of airfields)

Listen to the clearance. Like I've said before ATCOs have to think carefully about the wording to avoid ambiguity (and therefore most of the time will get it right)... pilots have to listen carefully to the clearance and fly it as given. If in doubt ask... approaching feather ruffling stage once again!!!!

Thinking on about this.... if the Controller doesn't want you to fly the SID profile before climbing to the higher cleared level, why would he used the phrase "SID" in the first place... surely a non-standard release clearance would be more appropriate?

Using the SID would ensure that any noise restrictions would be complied with, if you go down the route of a non-standard clearance you run the risk of making the clearance very wordy or open to misinterpretation. Funnily enough he/she managed to do that anyway...

CHECK YOUR PM's

Slaphead... As a Controller I understand SID's, why they are used etc... and that to give a non-standard clearance could be wordy.

If you re-read my previous posts you will see I was simply offering Six-Delta an interpretation of the instruction he had been given that started this thread in the first place?
