PPrune Radar, I love this forum, I learn so much!
Anyway, here is a question about SIDs. Lets take the STN CPT 3R as an example. There are two stop heights, both 3000 feet (for historical reasons I suspect), one before BKY and one after BKY. We almost always get cleared to FL70 prior to these points, then generally we will get radar vectors at some point further on, but we always go for an "open Climb" which means we don't stop at the stop heights. We do usually say "climb unrestricted" but now you have posted your reply above, I think we are doing this wrong and should maintain the 3000 feet limit until we're past the second (post BKY) stop height and then climb to FL70. We always follow the SID laterally.
It has never been queried by ATC.
Its not a problem either way for us to do in the aircraft.
