A mounting system configured to mount a personal electronic device having a PED display in an aircraft flight deck and provide a visible indication when a fault condition exists concerning the display of critical aeronautical information on the PED display, the PED comprising a commercial tablet device having a Hall Effect sensor configured to selectively shut off the display backlight and/or going into a standby or other low power state where the display is no longer illuminated, the mounting system comprising: an annunciator light comprising an electrically actuated color indicator for providing an annunciation regarding the PED; a display disable system mounted within the mounting system for disabling the PED display, wherein the display disable system comprises a magnetic kill switch, wherein the magnetic kill switch comprises a combination of one or more permanent magnets and one or more electrically actuated magnets, wherein the one or more electrically actuated magnets, when enabled, causes, in combination with the one or more permanent magnets, the Hall Effect sensor of the PED to shut off the display backlight and/or cause the PED to go into the standby or other low power state where the display is no longer illuminated; and a controller configured to: obtain a captured frame of the PED display; send the captured frame to a data integrity entity for determining whether a problem exists with an image displayed on the PED display; and responsive to receiving an annunciation indicator from the data integrity entity indicating that the problem exists with the image displayed on the PED display, enable the display disable system to enable the one or more electrically actuated magnets to cause the Hall Effect sensor to shut off the display backlight and/or cause the PED to go into the standby or other low power state where the display is no longer illuminated and command the annunciator light to illuminate in a particular color that indicates that the PED display was shut off because the problem exists with the image displayed on the PED display. an annunciator light comprising an electrically actuated color indicator for providing an annunciation regarding the PED; a display disable system mounted within the mounting system for disabling the PED display, wherein the display disable system comprises a magnetic kill switch, wherein the magnetic kill switch comprises a combination of one or more permanent magnets and one or more electrically actuated magnets, wherein the one or more electrically actuated magnets, when enabled, causes, in combination with the one or more permanent magnets, the Hall Effect sensor of the PED to shut off the display backlight and/or cause the PED to go into the standby or other low power state where the display is no longer illuminated; and a controller configured to: obtain a captured frame of the PED display; send the captured frame to a data integrity entity for determining whether a problem exists with an image displayed on the PED display; and responsive to receiving an annunciation indicator from the data integrity entity indicating that the problem exists with the image displayed on the PED display, enable the display disable system to enable the one or more electrically actuated magnets to cause the Hall Effect sensor to shut off the display backlight and/or cause the PED to go into the standby or other low power state where the display is no longer illuminated and command the annunciator light to illuminate in a particular color that indicates that the PED display was shut off because the problem exists with the image displayed on the PED display. obtain a captured frame of the PED display; send the captured frame to a data integrity entity for determining whether a problem exists with an image displayed on the PED display; and responsive to receiving an annunciation indicator from the data integrity entity indicating that the problem exists with the image displayed on the PED display, enable the display disable system to enable the one or more electrically actuated magnets to cause the Hall Effect sensor to shut off the display backlight and/or cause the PED to go into the standby or other low power state where the display is no longer illuminated and command the annunciator light to illuminate in a particular color that indicates that the PED display was shut off because the problem exists with the image displayed on the PED display.
