and off the top of my head.....as i am also at home......ecowings type 2 will not give you 45 mins hold over in snow ....not with the chart we use.....i am pretty certain it is 15mins up to 35 mins....but we have to put the lower time down on paper......thats with a 75-25 mix.
according to the AEA which is the chart we used for some time.. 75/25 | Type II | Ecowing 26
-3 and above = 15-30 minutes
-3 to -14 = 10-20 minutes
although there are many different hold over charts out there, as we have found that the various airlines we have de-iced over the years some kick up a fuss when the chart we use is different to theirs, as far as i can remember the EZY hold over chart, cant remember what one they use i think its Transport Canada.. will give 1:05-1:55 in freezing fog (-3 and above) where as the AEA will give you 0:25-1:00 in the same conditions... theres a significant difference
