Hello all.
ICEMAN,
You are right for the commercial jets but consider the possiblity of using the anti-icing on RJs or large turboprops at the airports without appropriate facilities (Canada is coming into mind, just from personal experience).
Also, some jets are designed to use the l/e anti-icing system on the ground. Good examples are Challengers (600 series, 300 series), Gulfstream as well as Bombardier's RJs (200, 700, 900).
They are all capable of using the stuff on the ground. During design of these models it was assumed that there will be no facilities for spraying available all the time.
The biggest problem was that too much bleed air would damage the l/e ribs plus too much heat just in front of you fuel tank would be a big no-no
I've seen ribs from test Challengers being black completely around the anti-icing going trough the leading edge
However one can assume the problem was more on the side of design i.e. improperly designed anti-icing system or better too much bleed air removed from the engine.
Amway, using bleed air on the ground is a considerable possiblity, especially on remote airfields.
Cheers
