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.
