>Does anyone have a picture of a compass, showing all or most >of the radials. What sort of aircraft, Mike? 777? 747-400?The 767, of course, doesn't have a full compass rose display (unless you're talking about the RDMI?).Here's a full compass rose on a 744...http://www.ozemail.com.au/~iriddell/VORIRSAtt2.JPGCheers.Ian

>The 767, of course, doesn't have a full compass rose display Hmm... it doesn't?What about FULL/CTR MAP, ILS/APP, and VOR mode? They show the full compass rose as far as I can see... (There's even that picture of a 757/767 EHSI with the FULL/CTR VOR mode in a Swedish '90's encyclopedia. :-))Martin767 fetishistIt's a lot like life and that's what's appealing

Glad someone was awake, Martin.... I certainly wasn't :-)I forgot about VOR and ILS.Thanks (for putting me straight).Cheers.Ian.P.S. I guess it's a case of "use it or lose it" (This sort of stuff never breaks down on a 767).P.P.S. By the way, perhaps you can remind me what this is:http://www.ozemail.com.au/~iriddell/767/XXXX.jpg:-)

*Scratching my head*Didn't you ask this same question before and someone sent you a graphic?http://ftp.avsim.com/dcforum/DCForumID33/483.html

Some invention by a third grader? A junkyard?Or whatever equipment bay it is that's under the control column on the... 767? I'm guessing the cable are from the control column, but it maybe the cable-storage compartment. :-)Martin767 fetishistPS. (Some) 767s also have a Centered/Full Map mode.It's a lot like life and that's what's appealing

HiHow about Electric trim controller?Could be aft as well (APU Bleeds).

>Some invention by a third grader? A junkyard? >>Or whatever equipment bay it is that's under the control >column on the... 767? I'm guessing the cable are from the >control column,Excellent deduction, Martin...It is indeed under the feet of the F/O :-) The cables are most likely for the F/O's rudder pedals, but I'll have to confirm this. The device in the center of the screen however, is a "waveguide switch". On aircraft with dual weather radar installations (L&R systems), there is still only one antenna, so it is necessary to switch the antenna back and forth between the two transmitter-receivers. The waveguides are hollow rectangular tubes which transmit microwaves back and forth to the antenna. The switch is an electromechanical device which simply channels the microwaves one way or another using an L-shaped cavity.I think the pilots would be quite surprised to see what actually is in this compartment (unfortunately, there is no access to it from the flight deck). I'm sure that your average F/O would not be comforted to know that his/her rear end is only about 6ft (2m) away from a very large bottle of compressed oxygen (the faster they make that promotion to Captain, the safer they are (grin)).Other goodies in there include the stick shaker (stall warning) mechanism, foot heaters (for cold mornings), the autothrottle drive motor and a spiders web of throttle and control cables.>PS. (Some) 767s also have a Centered/Full Map mode. Thanks! You learn something new every day (Unfortunately, as you get older, you also forget something every day ;-) ).Cheers.Ian.

>Hi >>How about Electric trim controller? Good guess, Ron.... :-)but it's kind of a trick question.... The device in the center of the picture is unrelated to the cables above it. I think the Boeing design engineers simply attached the weather radar waveguide switch (see message above) to a handy point in this area... which just happened to be the control cable mount.I'm not 100% sure what the cables are for, but, as of yesterday, I now have access to a complete set of 767 Engineers training notes (digital format), so it shouldn't take me too long to find out :-)Cheers.Ian.

Interesting as always, hehe. :-)If something happens the next time I'm on a 767, and they ask if there's a mechanic on board, I can always answer "I'm not a mechanic, but I do read internet flight sim message boards!" ;-)Martin767 fetishistIt's a lot like life and that's what's appealing

[Guest Ian_Riddell]

My latest theory.... :-)The diagrams in my training notes seem to indicate that these are (rudder pedal) wheel brake control cables. Shown in the photograph, are the right (side) wheel Normal and Alternate brake system cables. This shot was taken on a 767-300. Apparently, the 767-200 only has one pair of cables for both normal and alternate brakes (per side).Cheers.Ian.
