De-icing v's Anti-icing
DD. Thanks. Read and understood. Just getting a bit precious in my old age I guess. JammedStab. I know some F/E's might have used the system as a De-icer on the ground. Problem is that without airflow over the leading edges is is very easy to overheat the area. It is for that reason that Lockheed advise non ground use. Probably get away with it 99% of the time if closely monitored, but not for this guy.
