Jim, anyone,
How does an aircraft radio compass work. --------------------------------------------

 Hank,
 They're not all that big. Almost every
 airplane I've ever flown had one. The only ones that did
 not didn't have a starter either. Go to a small local
 airport and someone will hand you one to look at.  Or you
 could just get a 1" solid state accelerometer to feed
 into a display. There are some discussions of all the above
 in old threads. I'll send a link or two when I'm
 home again. 
 Cheers,
 Jim T.

 that ships used to use them.  It seems they would not be
 effected by a submarine hull.  What am I missing besides
 they are very big.
