Abstract
An aircraft electronics system is provided that includes a radar system, a display, an embedded global positioning/inertial navigation system (EGI) and a processor. The radar system is configured to generate aircraft operational data. The display is configured to display the aircraft operational data. The EGI is configured to generate aircraft behavior components and the processor configured to override the aircraft operation data displayed on the display when at least one of the aircraft behavior components is beyond a defined limit, wherein potentially incorrect aircraft operational data affected by at least one of the aircraft behavior component is not displayed.
Claims20
An aircraft electronics system, the system comprising:
- a radar system configured to generate aircraft operational data;
- a display configured to display the aircraft operational data;
- an embedded global positioning/inertial navigation system (EGI) configured to generate aircraft behavior components;
- and
- a processor configured to override the aircraft operation data displayed on the display when at least one of the aircraft behavior components is beyond a defined limit, wherein potentially incorrect aircraft operational data affected by at least one of the aircraft behavior component is not displayed,
- wherein the processor stores altitude data from the aircraft operational data upon the aircraft behavior components reaching a first degree limit within the defined limit;
- and
- wherein the radar system loads the stored altitude data and tracks altitude starting from the stored altitude when the aircraft behavior components return to a second degree limit within the defined limit.
A method of operating an aircraft electronics system, the method comprising:
- determining aircraft operational data;
- monitoring aircraft behavior components;
- displaying aircraft operation data when the aircraft behavior components are within a predefined range;
- and
- displaying a not valid data message on a heads up display when at least one of the aircraft behavior components are outside the predefined range.
A method of operating an aircraft electronics system, the method comprising:
- determining the altitude of the aircraft;
- displaying the determined altitude;
- monitoring the roll of the aircraft;
- and
- when the roll of the aircraft reaches a first degree limit, displaying an information message indicating that the determined altitude is inaccurate and ceasing to display altitude.
