Captain Stable--
As I mentioned before, the only GPWS alert that I have received was reviewed at the time by me, the First Officer and the Flight Engineer...and it was decided that the warning was false, so we carried on with the approach.
Seems like a reasonable action to me, ie: everyone agreed.
The action was reported (Captains Report) to the Chief Pilot (ex-BA, by the way)...who agreed also.
Works good, lasts a long time.
Do you have a particular problem with this?
It is certainly not necessary to re-invent the wheel.
