1. In a first aircraft having a cockpit with a canopy, a device for aiding the visual spotting of a second aircraft in flight by the pilot of the first aircraft looking at the sky through the canopy, the device comprising:

an approximately vertical display device;

a first means for displaying on the display device a representation of the canopy;

a communication means for receiving position information relating to the second aircraft from an outside source; and

a second means for displaying on the display device, using the received position information, a symbol representative of the second aircraft such that the position of the symbol in relation to the displayed representation of the canopy corresponds to the position of the second aircraft in relation to the aircraft's canopy as seen through the pilot's field of view, wherein:

a horizontal axis and a vertical axis, whose intersection is representative of the position of the first aircraft on the display device, are also displayed on the display device.

2. The device of claim 1 , wherein:

the first means comprises a first memory that stores information representing the fixed elements of the first aircraft's cockpit that are present in the field of view of the pilot;

the second means comprises a second memory that stores the position information; and

said first and second means comprise, in common, a computing unit that combines information received from said first and second memories so as to display the symbol and the representation of the canopy on the display device.

3. The device of claim 1 ,wherein the communication means links the device to an air traffic control installation.

4. The device of claim 3 , wherein the communication means transmits a message from the pilot to the air traffic control installation.
