    Re: Compass card with more than 360 degrees
    From: Greg Licfi

    Lu,
     When I first saw the message header:
      "Re: Compass card with more than 360 degrees"
    I thought someone was going to bring up the Locars(SP?)Compass.
    That was a Compass that got some press about 1976 or so - it went from 0
    to 400 degrees - to make recprical bearings "easyer" no body got behind
    it though, and it went away. FYI: I teach flying & use this neat trick for
    reciprical headings:
    
             " The 2 + 2 Methode " :
    
    Example:
      If heading is 095 what is the recip?
    answer: can you add 2 to the first number and get less than 4?
            if so do it and then subtract 2 from the next number the
            third number will stay the same....
    
                        0   9  5
                        +2 -2  =
                       ___________
                        2   7  5
    
    Going back in the other direction recp of 275:
    
    
                       2    7   5
                      -2   +2   =
                     ________________
                       0    9   5
    
    It's not fool proof there is a 'dead band' between 000 & 019 degrees
    that doesn't work. Try it.
                             -Greg
