    As I understand it, there's an added problem in a plane because the plane
    tends to roll causing the gravity
    vector to oscillate.  Many of the WW2 era aviation sextants have mechanical
    averaging devices to compensate
    for this; mine has a 1 minute averager.  One minute at 300 miles per hour =
    5 miles.
