Final answer:
When ATC issues the clearance 'descend via MAZIE 2 Arrival, except maintain 11,000' on an RNAV arrival, the pilot should comply with published altitude and speed constraints until WACKI, then maintain 11,000 until a new altitude is given by ATC.
Step-by-step explanation:
When Air Traffic Control (ATC) issues the clearance 'descend via MAZIE 2 Arrival, except maintain 11,000' while approaching the PATUXENT (PXT) VOR to begin the MAZIE TWO RNAV ARRIVAL into Teterboro (KTEB), the pilot is expected to comply with all published altitude and speed constraints until reaching the WACKI intersection. After reaching WACKI, the pilot should then maintain an altitude of 11,000 until ATC provides a new altitude.
