gulliBell, I am sure that by saying he 'refused to believe the crew were fcking around with the EGPWS' Chuckles meant that he refused to believe the crew were attempting an approach in IMC up the valley. I agree with Chuckles, that would be madness. You are saying that if it all turned to crap and they went IMC the crew should then use the EGPWS as a tool to get themselves out of that situation. I agree with you, use whatever you can.
Maybe you and Chuckles are talking about different things? BB
