Claim:
1. An avionics system, comprising: an aircraft cockpit display; an avionics user interface device; and an electronic avionics controller in communication with the aircraft cockpit display via a first interface and with the avionics user interface device via a second interface, and having a third interface configured for communication with a personal electronic device, the controller further having a processor and machine readable storage media having instructions stored therein that, when executed by the processor, cause the processor to: after displaying the graphical element, establish a limitation on the functionality of the personal electronic device with respect to the avionics system, wherein the limitation includes preventing the personal electronic device from interacting with the graphical element by granting priority over the personal electronics device to the avionics user interface device such that an instruction to manipulate the graphical element from the avionics user interface device takes priority over an instruction to manipulate the graphical element from the personal electronic device; transmit avionics data including graphics instructions to the personal electronic device; determine an expected response to the avionics data from the personal electronic device, the expected response including at least one of a graphics response or a state change response; receive an actual response to the avionics data from the personal electronic device, the actual response determined based on the graphics instructions, and the actual response including at least one of an actual graphics response or an actual state change response; compare the actual response to the expected response; determine a data integrity level of the personal electronic device based on the comparison; and display a message on the aircraft cockpit display in response to the data integrity level indicating that a loss of data integrity of the personal electronic device has occurred.
