ATC assign descent below altitude constraint while on a RNAV STAR
Hello,
Just a quick question for you ATC guys?
If ATC clear an aircraft which is on a published RNAV STAR, to descend below an actual altitude constraint on the STAR. Can the aircraft descend to the ATC cleared altitude, ignoring the STAR constraint. Or should the aircraft respect the constraint and then further descent to the ATC assigned altitude. (The aircraft in question was cleared for the RNAV STAR.)
Thanks
