It's been a hectic couple of weeks, but thanks for reply M(F)S. Just for evryones info, the HOT's in your link wasn't up to date at time of publication (as per note). From the faa website and search Aircraft Ground Deicing, similar info, and with LOUT stated for Arctica in Table 7 (although I was sent a pdf doc in which it was Table10, but both docs FAA for winter 2010-11).
