737NG NEI
Recently I have seen some Captains using the wing tanks before the centre tank on the 737-800 to avoid non environmental icing on long 4 hour sectors. I don't see this procedure written anywhere and I'm just wondering what other 737NG drivers think? I have also been told that flying high speed with the wing anti ice on during the descent can warm up the wing enough to avoid nei. Again this does sound a bit strange to me!
