I am very pleased with the 737 and I am looking forward to the SU2 release but I have a strange bug.I have the 700 as my default aircraft and after starting FS and the engines I cannot arm the A/T but if I then select the 600 it works perfectly.The same thing happens if I first select the 600 and start the engines or for example change the scenery the A/T will not arm but if I then change to the 700 it works. Any ideas anybody please.

John, It sounds like your generators are off line. Bring up the overhead and double check that they are on. This has been the only reason that I know of why the A/T will not stay *on*.[h4]Best Wishes,Randy J. Smithhttp://img.villagephotos.com/p/2003-5/196432/winglets_lg.jpg

Thanks a lot Randy you have been a great help and solved my problem.I am now even more pleased with the aircraft. John
