ABSTRACT:
The invention is a control circuit for driving a position indicator along a map screen in an aircraft flight data display. The control circuit is electrically coupled to a navigational system from which it receives digital information. The control circuit includes a decoder for decoding this information and a pair of digital to analog converters for converting the decoded information to a first analog signal and a second analog signal. These two analog signals drive a pair of servo motors which are mechanically coupled to the position indicator.
