I'd say C. If you deiced those areas first, THEN the rest of the aircraft, it would be more readily apparent to the flight crew if ice/snow was recollecting on the first areas.

If you did hard-to-see areas first, sitting in icing conditions, you may have a problem that doesn't get caught before takeoff.

Just my guess.... the DC-8 flight engineer sitting next to me says to start at the tail.

The machine I fly, iceman sprays fuselage (if req'd), wings, then tail. Doesn't seem to be a type specific thing as every other aircraft in the CDF, from King Air to A380, is done the same way. Use your hold over guidelines. A pre departure inspection is considered to be optional if holdover time has not been exceeded. Do it regardless.

Yep C
Usually defined as the 'representative surface' - that area specifically designated on each aircraft to be viewable from the cockpit - so that the captain can see if there is any ice accumulation and is always the first area sprayed (and thus subject to the longest holdover time). It is pretty much always a spot on the wing (so as to be viewable if the captain should request 'just tips and tail')
