It is worth reading the Honeywell Pilot Guide for EGPWS XXII. From earlier posts it seems as if the equipment is being relied on when it is not designed for that purpose. The Pilot Guide says:
• The MK XXII is a Situational Awareness tool, and an alerting and
warning device. It is not to be used for navigation of the aircraft.
If you blindly follow EGPWS you could have an accident because it is not designed as an IFR low level (below Safety Altitude) navigation system.
