1. An electronic avionics system comprising:
- a comparator operably connected to a data source that derives real-time flight data regarding predetermined flight parameters and operably connected to one or more downstream critical systems that utilize the real-time flight data regarding predetermined flight parameters; and
a database accessible by said comparator, said database including ideal flight data regarding said predetermined flight parameters;
wherein said comparator categorizes said predetermined flight parameters and compares data from said data source and said ideal flight data regarding said predetermined flight parameters and determines if said data source is deriving corrupt data; and
wherein upon determining said data source is deriving corrupt data said comparator takes action to mitigate the effect of said corrupt data on one or more critical systems that utilize the data.

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.

18. 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.

19. The electronic avionics system of claim 26, wherein said second flight display'"'"'s transition from operating as a multi-function flight display to a primary flight display does not require pilot action.
-
20. The electronic avionics system of claim 26, wherein a critical flight operation is a flight operation for which regulations require an aircraft to have a back-up system for a primary flight display.
