Narrative:

We were cleared for the ILS approach runway 6 into teb. Confusion comes, if we were given 'cross dandy at 1500 ft' cleared ILS runway 6. Dandy as it turned out was a hard altitude due to newark departures. Having flown numerous ILS, with 99% of the clrncs worded 'cross (XXX pt) at or above,' I assumed this is what I heard from new york approach during the ILS runway 6 to teb. Therefore, I just elected to maintenance 2000 ft MSL and intercept the GS from there. This put us at dandy at 2000 ft. No mishap or incident occurred, but the controller was irate. The approach was briefed as per our operations specifications, but that mandatory altitude was missed. I guess I was programmed into the 'at or above' phrase and did not catch the mandatory altitude requirement. We did start down once the controller queried us on our altitude. Supplemental information from acn 589874: controller's statement to both pilots in informing us in a stern manner while in a critical phase of flight for approximately 12 seconds produces anxiety causing temporary loss of concentration. The radio is not a place for discipline especially during a very critical phase of flight.

Original NASA ASRS Text

Title: BE90 MISSED MANDATORY ALT XING RESTR ON ILS APCH TO TEB.

Narrative: WE WERE CLRED FOR THE ILS APCH RWY 6 INTO TEB. CONFUSION COMES, IF WE WERE GIVEN 'CROSS DANDY AT 1500 FT' CLRED ILS RWY 6. DANDY AS IT TURNED OUT WAS A HARD ALT DUE TO NEWARK DEPS. HAVING FLOWN NUMEROUS ILS, WITH 99% OF THE CLRNCS WORDED 'CROSS (XXX PT) AT OR ABOVE,' I ASSUMED THIS IS WHAT I HEARD FROM NEW YORK APCH DURING THE ILS RWY 6 TO TEB. THEREFORE, I JUST ELECTED TO MAINT 2000 FT MSL AND INTERCEPT THE GS FROM THERE. THIS PUT US AT DANDY AT 2000 FT. NO MISHAP OR INCIDENT OCCURRED, BUT THE CTLR WAS IRATE. THE APCH WAS BRIEFED AS PER OUR OPS SPECS, BUT THAT MANDATORY ALT WAS MISSED. I GUESS I WAS PROGRAMMED INTO THE 'AT OR ABOVE' PHRASE AND DID NOT CATCH THE MANDATORY ALT REQUIREMENT. WE DID START DOWN ONCE THE CTLR QUERIED US ON OUR ALT. SUPPLEMENTAL INFO FROM ACN 589874: CTLR'S STATEMENT TO BOTH PLTS IN INFORMING US IN A STERN MANNER WHILE IN A CRITICAL PHASE OF FLT FOR APPROX 12 SECONDS PRODUCES ANXIETY CAUSING TEMPORARY LOSS OF CONCENTRATION. THE RADIO IS NOT A PLACE FOR DISCIPLINE ESPECIALLY DURING A VERY CRITICAL PHASE OF FLT.
