IAA
Thanks Piltdown, clarification fully accepted and appreciated. The IAA is indeed very laissez faire on airlines and lets them do pretty much as the see fit. Its all part of a facillitate our "small open economy". I have also some knowledge in how they deal with ordinary ppls are they are pedantic in the extreme on many matters. It really is a gross imbalance. However this eirjet 320 was DUB based so there is no excuse for lack of oversight.
Anyway, as stated by another, EGPWS is not fool proof as is supposed to be overridden if you have a nuisance warning in day vmc and know where you are. Which the pilots thought they did! If we are honest we could all have done this, learn and be wiser.
