Systems and methods for isolating attitude failures are provided. In one embodiment, an attitude integrity and display system comprises a display system comprising a primary system displaying a first attitude solution and a standby system displaying a second attitude solution; an attitude integrity system generating an attitude integrity (AI) solution calculated from measurements from an attitude solution data source, the AI solution comprising an aircraft roll and pitch, the data source providing data independent from any data generated by inertial sensor flight instruments and not displayed on either the primary or the standby systems; and an attitude monitor that compares the first solution against the second solution. When the first solution deviates from the second solution by more than a threshold, the monitor identifies on the display system which of either the first or the second solution is failed based on which has a greater deviation from the AI solution.
An attitude integrity and display system, the system comprising:
An attitude integrity and display system for an aircraft, the system comprising:
A method for identifying a failed attitude solution on an aircraft having a primary aircraft display system for displaying a first attitude solution and a standby aircraft display system for displaying a second attitude solution, the method comprising:
