Quick google brought this up: http://www.meriweather.com/747/compass.html -----Original Message----- From: Navigation Mailing List [mailto:NAVIGATION-L@LISTSERV.WEBKAHUNA.COM] On Behalf Of Maurice Millard Sent: Monday, February 07, 2005 1:13 PM To: NAVIGATION-L@LISTSERV.WEBKAHUNA.COM Subject: Compass's in B747's George Huxtable Wrote Finally, I think it was Trevor who referred to the carriage of magnetic compasses on aircraft as a thing of the past. I remember reading, can't recall where, some time in the last 15 years or so, that it was still a requrement for modern civil aircraft to carry some sort of magnetic compass, to offer some sort of guidance to the pilot if everything else failed, and that every 747 had such a compass tucked away at the corner of the windscreen. Can anyone confirm (or refute) this? Would a modern pilot have any idea how to apply magnetic variation? George. @@@@@@@@@@@@@@@@@@@@@@@@@@@@ Yes, I can confirm the presence of same. Actually the compass was mounted to the center windscreen post, so either pilot could read it. Since all other systems are electronic/electrical I guess it makes sense to have some sort of backup.
