OK here's one. If an aircraft is descending to your level and you are only 2000 feet clear of terrain and generates a descend RA you may get a EGPWS/GPWS pull up before being clear of the conflict.
I am particularly interested in the A320 here. I cannot see that the EGPWC will prevent the descend RA. Therefore you will get a Descend RA swiftly followed by a pull up - which of course must be followed!
Anyone elaborate on this interesting discussion point?
