Aircraft visual approach/landing reproducer device and system
First Claim
1. An airborne visual approach/landing reproducer device and system comprising a miniature runway fixed within the aircraft, an endless belt with horizon line and cloudspace depicted thereon positioned beyond the far end of the said miniature runway, a video camera mounted for multiple degrees of freedom in proximity to the said miniature runway, means for positioning the video camera proportionately and in exact scalar value to the position and movements of the said aircraft with respect to its selected ground-based runway, gyro means for tilting the video camera about its three axes that correspond to the tilt of the said aircraft about its axes of roll, pitch and yaw, airborne electronic receivers responsive to ground transmitters that define runway longitudinal axis, glide slope axis, path distance to and along the said ground runway, marker beacon, a radio altimeter, a navigational transceiver, electrical, electronic, and photoelectric circuitry interconnecting the said video camera drive means for positioning the said video camera, a cathode ray tube for presenting to the aircraft pilot the imagery detected by the aid video camera as it approaches the said miniature airborne runway and means for raising or lowering the said horizon line in unison with the raising and lowering of the said video camera, and additional video cameras located within the said aircraft for focusing on installed instruments, and switching means for selecting and/or mixing one or the other of said additional video camera outputs through closed circuitry connecting the said cathode ray tube visible to the pilot of the said aircraft.

Abstract
A cockpit-mounted cathode ray tube presents to the pilot a visual equivalent of the approach/landing during obscure visibility of an aircraft which contains a miniature illuminated runway that is being "approached" by a video camera that reproduces the position and position changes of the aircraft with respect to the real runway. Ground-based instrument landing system elements are used to air derive radio information to secure the operation of the device.
