Thx for your input. The aeroplane I fly has no GPS but RAAS. In the meanwhile I received some valueable info from Honeywell about architecture of RAAS. Looks like EGPWS, which is feeding RAAS, has it's own GPS receiver. My FCOM is very thin about that stuff.

Ah, one of my pet projects at our carrier.....
It is EXTREMELY IMPORTANT to have a direct GPS feed to one's EGPWS. Even an FMS with GPS position input/feed will not provide maximum protection.
