I goofed the radius, sorry. It's currently a 7cm wide ball, which is too small, but looks about right on the current panel. The one I checked in was generated from a script that still had 15cm listed as the target diameter. > also, i looked at pictures of the a4 panel and i didn't see such an > instrument. It's right in the center of the panel of the A-4M photos here, to the left of the radar screen: http://209.133.73.63/AWA/AWA_001-100/AWA_021-030/walk26_A-4M/part2/walk026B.htm This is just the ball -- the real instrument sits in an enclosure that makes it look much more like a conventional artificial horizon. It's also possible that you were looking at pictures of a newer aircraft -- late model A-4's (like those in service in New Zealand -- Gene had a great link to some photos of thes) have HUDs and a much smaller backup horizon with only 2 DOF. This type of 3DOF horizon/compass was popular in military jets in the 50's and 60's, but was phased out in favor of the smaller units to save panel space after HUDs became availble. I'm willing to bet that they were maintenance nightmares, too. After all the trouble I went through trying to get this thing to look right in software, let me say that I am in complete awe of the mechanical genius who made the thing work out of gears and gyros.
