ACR WDB LANDED SHORT OF DISPLACED THRESHOLD.

Narrative

WE WERE ON A BASE LEG FOR AN ILS TO RWY 22L AT JFK. WX WAS 600' OVCST AND RAIN. THE WIND WAS 190/18. A WDB Y RPTED POOR BRAKING. WE WERE THEN SWITCHED TO AN ILS RWY 22R. THE CAPT WAS FLYING AND BRIEFED THE APCH FOR 22R. WE BROKE OUT AT 600' AND THE CAPT INCREASED HIS DSCNT RATE BECAUSE IT APPEARED WE WERE HIGH. OUR DSCNT RATE VARIED FROM 1200-1500 FPM DOWN TO ABOUT 150' AT WHICH TIME A NORMAL DSCNT WAS STARTED. MY PRIMARY ATTN WAS FOCUSED ON CALLING OUT THE AIRSPEED AND EXCESSIVE SINK RATE ALONG WITH MONITORING RWY ALIGNMENT. AS WE STARTED TO FLARE FOR A NORMAL LNDG; WE NOTICED THAT WE WOULD LAND SHORT OF THE DISPLACED THRESHOLD. WE LANDED APPROX 800-1000' SHORT OF THE DISPLACED THRESHOLD. THE DISPLACED THRESHOLD IS APPROX 3000' FROM THE END OF THE RWY. I FEEL THAT THE PRIMARY CAUSE WAS A VERY LIMITED AMOUNT OF TIME TO BRIEF THE APCH. NO ONE NOTICED THAT THE RWY HAD A DISPLACED THRESHOLD WITH A RPT OF POOR BRAKING AND A XWIND. THE CAPT WAS CONCENTRATING ON MAKING AN ON-SPEED LNDG IN WHAT HE THOUGHT WAS THE T/D ZONE. I WAS CONCENTRATING ON MAKING MY REQUIRED CALLOUTS. BY THE TIME WE NOTICED THAT WE WOULD LAND SHORT OF THE DISPLACED THRESHOLD; IT WAS TOO LATE TO MAKE ANY ADJUSTMENTS. ONE SOLUTION MIGHT BE TO ADD AN ABBREVIATION FOR DISPLACED THRESHOLD (DT) AFTER THE APCH NAME ON THE COMMERCIAL CHART PAGE. EXAMPLE: ILS 22R (DT). WITH THIS FORMAT; AS SOON AS YOU LOOK AT THE APCH NAME; YOU WOULD KNOW THAT THE RWY HAS A DISPLACED THRESHOLD. SUPPLEMENTAL INFO FROM ACN 93708. SHOULD HAVE RESISTED THE URGE TO DUCK UNDER. ALSO I WAS NOT THINKING ABOUT THE DISPLACED THRESHOLD; AFTER FIRST STARTING THE APCH FOR 22L.
