To Peter R. and Gary Mishler. Say for sake of argument that the pilots
missed a thin layer of frost. If discovered, are there any remedies short
of a full, formal deicing?


I am not qualified to answer as I have no experience in anything greater
than a single engine piston aircraft.

That said, when my aircraft was frosted over in those three incidents, my
only fly-able option was to request a complete aircraft deicing.

Fortunately, in all three cases the line crew was available, had the deice
fluid nearby, and did it for free. I tipped them generously.

If deicing were not an option, I would have had to get a hotel and wait
until the frost melted off the next day, or some liquid deicing were
available. In no case would I have attempted to take off with it on the
wing surface.

Why? It is acceptable to "polish the frost smooth" per FAR 91.527.
