Honeywell DB sucks!
We operatre in remote area's, that said the DB that honeywell uses is not complete.
CASA Australia last year launched an investigation to DB problems and false EGPWS warnings.
These got to be such a problem that crews were getting hard warnings in IMC and carrying out mandatory actions so often that investigatons needed to be made.
Several of our utility aircraft were flown with the inhibit button for nearly all operations that it negated the $50k "E" part of EGPWS.
In the big picture however it is like the old days of having a third set eyes in the cockpit, and will undoubtably save someones bacon.
