Abstract
The present general inventive concept relates to a system of method having an electronic flight display that meets the FAR 23.1311(b) regulatory requirement for redundant backup instruments in the cockpit. The present general inventive concept also provides a system and method to detect failures, obstructions, or improper operation of the aircraft pitot pressure sensing system using a combination of dissimilar sensor data that is independent from each other, e.g., allocated from different sources and employed for different purposes on different displays, and displays information on an avionics display screen.
Claims14
An electronic avionics system comprising:
- a first avionics display operably connected with a first air data computer and a first attitude computer;
- a second avionics display operably connected with a second air data computer and a second attitude computer;
- and
- a communications connection linking said first and second avionics displays;
- wherein information is transmitted between said first and second avionics displays via said communications connection.
An electronic avionics system comprising:
- a first avionics display that is configured to operate as a primary flight display during flight operations;
- a second avionics display that is configured to selectively operate as a multifunction display while said first avionics display operates as a primary flight display;
- and
- a communications connection linking said first and second avionics displays,
- wherein information is transmitted between said first and second avionics displays via said communications connection, and
- wherein said second avionics display operates as a back-up to said first avionics display by operating as a primary flight display if said first avionics display stops operating as a primary flight display during critical flight operations.
