I never argue with Canadians when it comes to cold weather but the HOT times vary greatly depending on the mix and type of fluid.
I used 'Kilfrost ABC-4 substain Type IV with a ratio of 100/00
The tables say: Freezing Fog 1 -1.50 hrs
Snow 30 - 55 mins
Freezing DZ 40 -1.05 min/hr
Temp range -3c and above. I took the conservative low end of 40 min
We could never go with 2 to 5 mins, it takes us around 8 minutes to push back and start. (four eng and no auto-start 747). Normally can get airborne around the twenty minute mark. Also the HOT times start from the begining of application so your tables are not the same as we use. Anyhow you can have your 'white scenery' I have a few trips in the sun now.
