Tim,

You may need to edit that note. Your note as written implies that
AHRS means Artifical Horizon and that's not accurate.

AHRS means Attitude and Heading Reference System. An AHRS is a much
more capable system than an AH since it provides (at a minimum) pitch
attitude, roll attitude and heading.

Wouldn't it be better to just quote the rule?

To go off on a tangent - I wonder how many CDs would recognize a Bohli
compass and know what to say about it.
