EGSS departure, cleared CLN1E SID. No altitude given in ACARS PDC. Filed FL350.
To re-iterate, no mention of altitude whatsoever in ATC clearance. No "maintain 4000". No "climb via SID' (it's my understanding the UK has not implemented this phraseology per PANS-ATM 6.3.2.4).
Is crew simply expected to comply with level and speed restrictions and maintain 6000 until cleared higher?
Apologies, I only operate in the UK once every year or two. Prepared for admonishment, yes I should know, etc etc.
