1. A display system comprising:
a head-up display installed natively on board an aircraft,
a first display computer installed natively on board the aircraft, a second display computer for displaying information linked to at least one of in-flight test parameters or conditions, and
a mixing device for mixing a first video signal and a second video signal to form a third video signal, the mixing device comprising electronic circuits configured such that the third video signal is representative of the first video signal when the amplitude of a control signal is lower than a first predetermined threshold and such that the third video signal is representative of the second video signal when an amplitude of said control signal is greater than a second predetermined threshold,
wherein the first video signal is generated by the first display computer, the second video signal is generated by the second display computer and the third video signal is configured to control a display on the head-up display.
