Abstract
A multi-product avionics control and display unit (CDU). In implementations, the CDU may include a display and a processor coupled with the display. The processor is configurable to operate in a first mode to cause the display to present standby primary flight information associated with the aircraft and a second mode to control and display operation of one or more aircraft systems associated with the aircraft.
Claims20
An avionics control and display unit (CDU) for use in an aircraft, the CDU comprising:
- a switch;
- a display;
- one or more memories operable to store an avionic controller module and a primary flight mode module;
- and
- one or more processors coupled with the switch, the display, and the one or more memories, one or more of the processors being configurable to:
- operate in a first mode to execute the primary flight mode module to cause the display to present standby primary flight information associated with the aircraft, and
- operate in a second mode to execute the avionic controller module to control and display operation of one or more aircraft systems associated with the aircraft,
- wherein the one or more processors default to operation in the first mode after activation of the switch.
An avionics control and display unit (CDU) for use in an aircraft, the CDU comprising:
- a display;
- a first memory operable to store a primary flight mode module;
- a second memory operable to store an avionic controller module;
- a first processor coupled with the first memory, the first processor operable to execute the primary flight mode module to generate a first video signal comprising standby primary flight information associated with the aircraft;
- and
- a second processor coupled with the second memory, the second processor operable to execute the avionic controller module to generate a second video signal comprising aircraft systems information associated with the aircraft,
- wherein the first and second processors are independent and operable to simultaneously execute the respective modules to generate the first and second video signals.
An avionics control and display unit (CDU) for use in an aircraft, the CDU comprising:
- a video mux;
- a switch coupled with the video mux;
- a display coupled with the video mux and operable to display a selected video signal received from the video mux;
- a first memory operable to store a primary flight mode module;
- a second memory operable to store an avionic controller module;
- a first processor coupled with the first memory and the video mux, the first processor operable to execute the primary flight mode module to generate and provide a first video signal to the video mux, the first video signal comprising standby primary flight information associated with the aircraft;
- and
- a second processor coupled with the second memory and the video mux, the second processor operable to execute the avionic controller module to generate and provide a second video signal to the video mux, the second video signal comprising aircraft systems information associated with the aircraft,
- wherein the first and second processors are independent and operable to simultaneously execute the respective modules,
- wherein the activation of the switch causes the video mux to select the first video signal as the selected video signal for presentation by the display.
