Well argued HC! The splutterings of abuse from across the pond demonstrate the correctness of your position. The EGPWS on the A330 is really great - for our enviroment but of really little application in the rotary area of operation. I can really imagine all the mobile rigs having a position on every AIRAC 28 day cycle in the EGPWS database! The last database update we had was about 8 months ago and it has to be really big to get an amendment. We have a specific statement from Honeywell that the database does not include man made structures so it would be interesting to see in the fixed platforms would even be included. I would also be interested in how a Terrain Cleararance Floor would be constructed for an IFR approach into the ESB with multiple but maybe not accounted for man-made obstructions.
