Moving map display
First Claim
1. A moving map display showing features and other information regarding the area about a moving aircraft wherein a navigation system thereon indicates the position of the craft, wherein a mapped area is made up of a number of contiguous smaller area map segments with each map segment being stored as a video signal in a video storage means, and said map display has a composite map segment displayed that may be made up of portions of more than one stored map segment comprising:
- switching means connected to said navigation system indicating the position of said craft for selecting, in response to information from the navigation system, ones of said stored map segments, portions of the video signals of which are required to make up said composite map segment to be displayed, andread means, under control of said switching means, for reading portions of the video signals for said selected map segments from the video storage means to make up said composite map signal.

Abstract
A moving map display used on an aircraft or other moving vehicle is disclosed. Discreet map segments are stored on a video signal storage means and portions of the video signals for several map segments are read from the storage means and combined to create a composite map segment which is displayed within the aircraft or other moving vehicle. A navigation system on the vehicle provides position information to a microprocessor which functions with other circuitry to determine which map segment portions are to be combined to create the composite map segment.
