Narrative:

Descending on the korry one arrival to lga approximately XA20L, we missed making the hard 10000 ft at korry intersection. It was a little difficult descending the 2000+ ft from holey intersection to brand intersection at 11000 ft in 6 mi. While we were remarking on that, we both also kind of missed the need to be at 1000O ft 5 mi short of robbinsville. It was the first time on the arrival for both of us. We had an FMS, but no HSI display, and I do not think the diagramming helped, ie, having the liens of the holding pattern at rbv confuses things a bit. It was also at that point, between brand and korry, that we were told to switch frequencys from center to approach control, and that distracted me from paying attention to business. No mention was made by the controller on the switch as I announced something like, '11000 on the arrival,' and it did not appear that there was a problem with traffic separation on our TCASII display because of our mistake. As we approached korry, I said 'shouldn't we be at 10000,' and the first officer agreed. The controller didn't say anything about it, and neither did we. I would guess at korry we were descending out of 10600 ft. Callback conversation with ZDC specialist revealed the following information: a ZDC specialist advised that ZDC has notamed the following changes to the korry STAR due to the steep descent gradient between holey and brand intxns: change: 'cross brand at 11000 ft' to: 'cross brand at or above 11000 ft.' add: 'cross davys at or above 13000 ft.' change: 'cross skipy at or above FL190,' to: 'cross skipy at or above FL190, and at or below FL220.' these changes allow a descent gradient of 273 fpnm. The revised STAR is expected in early april. Controller's have been briefed to issue verbal amendments to the present STAR restrs.

Title: S80 FLC UNDERSHOOT DSCNT XING RESTR ON KORRY ONE STAR.

Narrative: DSNDING ON THE KORRY ONE ARR TO LGA APPROX XA20L, WE MISSED MAKING THE HARD 10000 FT AT KORRY INTXN. IT WAS A LITTLE DIFFICULT DSNDING THE 2000+ FT FROM HOLEY INTXN TO BRAND INTXN AT 11000 FT IN 6 MI. WHILE WE WERE REMARKING ON THAT, WE BOTH ALSO KIND OF MISSED THE NEED TO BE AT 1000O FT 5 MI SHORT OF ROBBINSVILLE. IT WAS THE FIRST TIME ON THE ARR FOR BOTH OF US. WE HAD AN FMS, BUT NO HSI DISPLAY, AND I DO NOT THINK THE DIAGRAMMING HELPED, IE, HAVING THE LIENS OF THE HOLDING PATTERN AT RBV CONFUSES THINGS A BIT. IT WAS ALSO AT THAT POINT, BTWN BRAND AND KORRY, THAT WE WERE TOLD TO SWITCH FREQS FROM CTR TO APCH CTL, AND THAT DISTRACTED ME FROM PAYING ATTN TO BUSINESS. NO MENTION WAS MADE BY THE CTLR ON THE SWITCH AS I ANNOUNCED SOMETHING LIKE, '11000 ON THE ARR,' AND IT DID NOT APPEAR THAT THERE WAS A PROB WITH TFC SEPARATION ON OUR TCASII DISPLAY BECAUSE OF OUR MISTAKE. AS WE APCHED KORRY, I SAID 'SHOULDN'T WE BE AT 10000,' AND THE FO AGREED. THE CTLR DIDN'T SAY ANYTHING ABOUT IT, AND NEITHER DID WE. I WOULD GUESS AT KORRY WE WERE DSNDING OUT OF 10600 FT. CALLBACK CONVERSATION WITH ZDC SPECIALIST REVEALED THE FOLLOWING INFO: A ZDC SPECIALIST ADVISED THAT ZDC HAS NOTAMED THE FOLLOWING CHANGES TO THE KORRY STAR DUE TO THE STEEP DSCNT GRADIENT BTWN HOLEY AND BRAND INTXNS: CHANGE: 'CROSS BRAND AT 11000 FT' TO: 'CROSS BRAND AT OR ABOVE 11000 FT.' ADD: 'CROSS DAVYS AT OR ABOVE 13000 FT.' CHANGE: 'CROSS SKIPY AT OR ABOVE FL190,' TO: 'CROSS SKIPY AT OR ABOVE FL190, AND AT OR BELOW FL220.' THESE CHANGES ALLOW A DSCNT GRADIENT OF 273 FPNM. THE REVISED STAR IS EXPECTED IN EARLY APRIL. CTLR'S HAVE BEEN BRIEFED TO ISSUE VERBAL AMENDMENTS TO THE PRESENT STAR RESTRS.
