The device for checking speed intended for an aircraft ready to land on deck on a moving vehicle, the aircraft having a current vertical speed, called the first speed, and a threshold value of vertical downward speed relating to the vertical speed of the moving vehicle, called the low threshold, the ship having an absolute vertical speed, called the second speed, comprises a display and means for receiving data originating from the aircraft, notably its vertical absolute speed. The device includes a calculator making it possible to generate on the display a graduated speed gauge including a fixed cursor indicating the first vertical speed and a second moving cursor indicating the speed of the ship, a third moving cursor indicating the low threshold, the graduation being centered around the value of the first vertical speed.
