Ground Deicing
« on: December 20, 2019, 05:10:14 pm »
This PC-12 accident should be a good reminder to all of us Commander guys:

Don't take off with ice adhering to the airplane, and don't take off in heavy snow or freezing rain period... unless properly deiced, and even then, consider waiting. It's not that important to get there.

As a professional pilot, I had holdover tables and deicing fluid types hammered into me at each recurrent-- I'm not sure there is as much of an emphasis on that in typical part 91 training.

Holdover time guidance can be found here:

I printed a copy out to keep in my aircraft this winter. I only rarely have to deal with ground deicing (once a year, at most, more likely once every few years), but it's handy to have when you need it.

When you have  freezing rain there is almost no holdover time.  It is just a no go!

By the time you get de-iced and taxi for departure your time is up.

Some airports will de-ice you at the the end of the runway, which makes a lot more sense.

Once you are airborne the impact of the condition change.
