Speed limit when off a SID
Hello,
This is probably an easy question to answer, but I cannot find a reference anywhere.
When departing on a SID, for example the SAM 1X from LGW, the procedure has a speed limit of 250kts all the way out to the SAM VOR. Quite often I will ask ATC if this applies and we are always then given free speed.
What happens if the controller takes you off the SID (using headings), does the SID speed restriction still apply or can you now determine that you are free to accelerate?
I know it is likely that the controller is issuing headings to maintain separation from other traffic and therefore may have an expectation that you will maintain the speed mandated in the procedure. It was a discussion I had with a colleague the other day but we couldn't find a reference for it.
Thanks
