AN ACR MLG CAPT BELIEVES THAT THERE SHOULD BE A 'CAR WASH' TYPE OF DE-ICING EQUIP AT LGA TO EXPEDITE DEPS AND PREVENT HAVING GO RETURN TO THE GATE IF GND TIME IS EXCEEDED AFTER DEICING.

Narrative

I WAS THE CAPT OF FLT X IN AND OUT OF LAGUARDIA ON JAN/SUN/93. IT WAS A SNOWY EVENING WITH SNOW FALL RATES RANGING FROM HVY TO LIGHT. WHEN WE LANDED; NO GATES WERE AVAILABLE DUE TO AT-GATE-DEICING. WE LEARNED OF A SEQUENCING PROC THAT COORDINATED DEICING AND TAXI-OUT; A CUE CTL; BUT NO ONE KNEW HOW TO INITIATE IT. THE FAA TWR PEOPLE KNEW OF THE PROC BUT; COULD NOT OR WOULD NOT INITIATE IT. OUR COMPANY OP CTLS COULD NOT OR WOULD NOT. I EVEN SENT AN ACARS MESSAGE TO SYS ON ITS NEED. BUT; IT WAS NOT INITIATED. TYPE II DE-ICE FLUID IS NEW TO LGA. IT WAS AVAILABLE AND IN USE. BUT; THERE WAS LITTLE COM WITH DE-ICE CREW AND THE COCKPIT. FURTHER; THE COMPANY OPS CTLR STATED THAT DE-ICING WAS A 2 TRUCK OP. BASED ON THAT INFO AND THE LACK OF DIRECT COM WITH THE DE-ICE CREW; FLTS WERE DELAYED ON THE GATE AWAITING A SECOND DE-ICE TRUCK THAT DID NOT COME. THE DE-ICING WAS IN FACT A 2 STEP PROC USING TYPE I AND II FROM THE SAME TRUCK. THE DE-ICING INFO WAS BEING RELAYED TO THE COCKPIT VIA THE PUSHBACK CREW; NOT THE DE-ICE CREW. THUS; CREWS WOULD NOT CALL FOR PUSHBACK BECAUSE THEY WERE AWAITING A DE-ICE COMPLETE MESSAGE. PUSHBACK CREWS WERE NOT RELAYING THE DE-ICE INFO TILL PUSHBACK WAS INITIATED. FLT Y PUSHED BACK AN HR AND 15 MINS LATE AT MM00 PM. WE HAD BEEN DE- ICED WITH BOTH TYPES OF FLUID. OUR 45 MIN HOLD OVER TIME STARTED AT LL53. WE TAXIED OUT TO FIND LGA IN A 1 RWY OP. WE WERE #12 FOR TKOF. WE WERE CLRED FOR TKOF AT MM37; 1 MIN BEFORE OUR HOLD OVER TIME EXPIRED. GIVEN THE LONG GATE DELAY GENERATED BY DE-ICING AT THE GATE; AND THE LONG TAXI-OUT TIMES; IT SEEMS LOGICAL TO ME THAT A 'CAR WASH' DE-ICE FACILITY BE CREATED AT LGA IMMEDIATELY.
