Icing

[337G]

Hi every one hope you all had a good Christmas and New Years.

Thank you for all the information you have provided it is all very good stuff.

For my two cents worth, I am partial to letting some ice build up on the leading edge before cycling the boots. My last job was flying a PC-12 into Canada's Arctic and I ran into alot of icing. On one trip shortly after the info came out about not waiting for the ice to build up I decided to do an experiment on a moderate iceing day. I let the ice build up first and then cycled the boots to watch the ice nicely break off. Then, I selected the "continuose" mode and the ice did remain clear however, there were areas on the leading edge that would not clear and formed the dreaded pocket. Fortunatly they were only in a couple of areas and not very big in width.

I am sure aircraft wing design has alot to do with it and so each individual airplane will be different therefore we must exercise caution for the first few hours untill we get used our particular airplane and are familiar with what it is capable of handling. But the best remedy is to avoid it when able.
