with reference to the gpws problems these occurred when gmonx was upgraded to egpws fit and there were some errors in the database from the supplier,so the system saw the rock in front of the acft and not just off to the left.....we filled in the asrs our r&d and management then could pull all data and get problem sorted....just what the safety system is supposed to do......but then thats not a story for the insight team.
