Hi, have a question for something I haven't been able to find a concrete answer for in literature.
You're on a star descending. You're given a "Cross THING at 12000." Non-charted restriction.
You're then given another clearance to cross another downstream waypoint, say, STUFF at 8000. Also non-charted.
You haven't yet crossed the first waypoint yet (THING).
Question is:
Is that first non-charted crossing restriction for the first waypoint still valid and to be complied with?
Any differences in this specific example between US and Canada?
You usually get altitudes that follow a similar angle down but sometimes a bit different.
Only regs I can find deal with charted restrictions or the VIA phraseology snafus.
Thanks

Re: Question for the terminal guys regarding crossing clearance.
A second crossing restriction will not cancel the first one.
Re: Question for the terminal guys regarding crossing clearance.
Thanks, that's what I thought as well as it makes the most sense and the safest approach. I get challenged on it occasionally and would like to find something that backs it up. I have yet to find anything that says a second clearance invalidates the first one. I think it may be a few people who are confusing it with charted vs non-charted clearances or being vectored off the star/rejoining.
