SID and Speed restrictions
I have a question regarding Speed restrictions when following and SID.
When flying out of various UK / London airports the SID will sometimes have Speed restriction of 220 kts and stop altitude 4000 - 6000 with and without step climbs.
As an example if you have an SID with 220 kts speed restriction to various waypoints on the SID, and your initial stop altitude could be as example 5000 ft on the SID, however before reaching this altitude and waypoint, you are cleared to FL100 or FL150, and you get the instruction to Climb Flight Level 150, nothing else in the ATC clearance.
Do you
1. Still adhere with the Speed restriction on the SID? (Despite being cleared to a higher level then the initial Climb level on the SID)
2. Do you still need to respect any climb restrictions (Altitude restrictions) on the SID prior to climbing the cleared level of FL150?
