Narrative:

On jan/fri/95 flying pit-bos prior to departure we had light rain. Neither the first officer nor I recall the ATIS calling for light freezing rain. We had just flown the aircraft from sfo. The wings were cold soaked and rain droplets might be freezing on the wing. We checked other parts of the aircraft and found no evidence of freezing rain. On taxi out we requested our wings to be deiced. The rain had stopped and our wings were deiced with type I fluid. Subsequently, we were told ATIS had reported freezing rain which would have required type ii to be used. The conditions did not appear to be freezing or of great concern. In fact, many aircraft were not requesting deicing. If freezing rain is falling, type ii should be used without the pilot requesting it.

Title: THE WRONG DEICING FLUID IS USED FOR THE RPTED CONDITIONS.

Narrative: ON JAN/FRI/95 FLYING PIT-BOS PRIOR TO DEP WE HAD LIGHT RAIN. NEITHER THE FO NOR I RECALL THE ATIS CALLING FOR LIGHT FREEZING RAIN. WE HAD JUST FLOWN THE ACFT FROM SFO. THE WINGS WERE COLD SOAKED AND RAIN DROPLETS MIGHT BE FREEZING ON THE WING. WE CHKED OTHER PARTS OF THE ACFT AND FOUND NO EVIDENCE OF FREEZING RAIN. ON TAXI OUT WE REQUESTED OUR WINGS TO BE DEICED. THE RAIN HAD STOPPED AND OUR WINGS WERE DEICED WITH TYPE I FLUID. SUBSEQUENTLY, WE WERE TOLD ATIS HAD RPTED FREEZING RAIN WHICH WOULD HAVE REQUIRED TYPE II TO BE USED. THE CONDITIONS DID NOT APPEAR TO BE FREEZING OR OF GREAT CONCERN. IN FACT, MANY ACFT WERE NOT REQUESTING DEICING. IF FREEZING RAIN IS FALLING, TYPE II SHOULD BE USED WITHOUT THE PLT REQUESTING IT.
