Redundant avionics for flight instruments: a plurality of aircraft flight data sensors, which provide data that are normally displayed on indicators in the cockpit, are transmitted to two independent computers. Each computer is associated with and creates images representative of data sensed by the sensors on a respective projected image display creation device which is in the form of a liquid crystal display, for example. Associated illumination sources and one common or two respective sets of optics project the images from each image creation device on a new screen. The image creation device and the optics would cause the image representative of data from the same sensor to be projected to the same location on the screen regardless of which computer and image creation device provided and projected the image. The computers are independently operable for selectively causing the display of information corresponding to data received from none, some or all of the sensors. For example, the computers are operable so that one display device will display information corresponding to data received from some of the sensors and the other display device will display information corresponding to data received from other sensors and the computers are operable so that each computer may cause display of information based on all of the sensors, as required.

[ What is claimed is:] [1.]1. Redundant avionics for aircraft instruments, comprising:a plurality of sensors for various displayable flight data;two computers each able to receive the data from all of the sensors and each of the computers being operable independently of the other computer;a respective projected visible image display creation device operated by each of the computers and each computer being operable to cause the respective display creation device to create an image representative of the data of selected ones of the sensors and to project those images;a display screen visible to an operator for receiving the images projected from each of the display creation devices and the display creation devices projecting images onto the screen; andswitching devices connected with the computers to selectively cause each computer to simultaneously create some of the images projected on the display screen through the respective image creation device.
