737 3/400 Wing De-ice
As far as I am aware MOST 737 EFIS operators have followed the Boeing recommendation to always select Wing De-ice whenever Engine Anti-ice is selected on whilst on the ground. ((I think BA and (old)GO differ on this). I have just recently come across some 737's that do NOT automatically drop the Wing De-ice switches at lift off. I thought that all 737's had been modified to do this so would be interested to hear any comments from other 737 Classic drivers!
