EGPWS?
What help might the all singing all dancing EGPWS have been to the crew in this situation. With AVAD they had a good chance of having two audio warnings: "Check Height" at bug height plus "One Hundred Feet". Either of these may have given the crew enough warning to be able to correct the situation (Although perhaps not enough warning if they were going backwards and down at 4000fpm as per the Australian Puma a few years ago). What warnings should EGPWS have given?
