Onward clearance - alt restriction
I know this subject has been discussed before, and I've searched for it, but can't find it.
Can anyone quote me chapter and verse (preferably from MATS) on the following:-
An aircraft is cleared on initial descent to, say, FL100, to be level by Point A, say the GWC. Descent starts. Before reaching either GWC or FL100, ATC clear them to a lower level or a further point on the flight plan without restating the level restriction. Is that level restriction thereby lifted?

From MATS Part 1 Section 1 Chapter 4 Page 4 Para 6.1
"When an amendment is made to a clearance the new clearance shall be read in full to the pilot and shall automatically cancel any previous clearance. Controllers must be aware, therefore, that if the original clearance included a restriction, e.g. 'cross ABC FL 150 or below', then the issue of a revised clearance automatically cancels the earlier restriction, unless it is reiterated with the revised clearance."

The answer to your question is Yes.
MATS pt 1 Section 1 Chapter 4
"When an amendment is made to a clearance, the new clearance shall be read in full to the pilot and shall automatically cancel any previous clearance.

Beat me to it Speke.... I'll leave it anyway

Eventually managed to find one example of a number of similar threads - pleased to be of some help (said in a deep manly voice!
