That bloody Carb Ice
ExclamationMark,
.......As a scenario it fits.
As I read it , core Icing when taxying in foggy conditions did not always lead to flameouts while running at low speed.If the engines had got any sort of ice in them you can bet your boots they would not be able to run properly or efficiently.Acceleration from idle revs would be bound to be somewhat reduced
.......This is the first I heard about severe icing in the LAM holding pattern before Final approach. Who says this? Whats his qualification to make the observation? Is it confirmable.Surely the AAIB interrogation would would have shown this up early on.
