A method and apparatus comprising an aircraft, a network interface, a display system, a sensor system, and a computer system. The network interface, the display system, the sensor system, and the computer system are associated with the aircraft. The network interface is configured to exchange data using a wireless communications link. The computer system is configured to run a number of processes to receive simulation data received through the network interface over the wireless communications link. The computer system is configured to generate simulation sensor data using the simulation data. The computer system is configured to receive live sensor data from the sensor system associated with the aircraft. The computer system is also configured to present the simulation sensor data with the live sensor data on the display system.
