1. An enhanced flight vision system comprising:
a display system for a cockpit of an aircraft, configured to allow information to be displayed on a display such that this information is visible to a pilot of the aircraft in a manner superimposed on surroundings outside the aircraft; and
an image acquisition system configured to acquire images of the surroundings outside the aircraft,
wherein the display system is configured to receive images produced by the image acquisition system and to display these images on the display,
wherein the display system is configured so as to:
acquire information about the flight path angle of the aircraft when the aircraft is approaching a runway;
calculate a difference between a flight path angle of the aircraft and a nominal angle corresponding to said approach towards the runway; and
compare an absolute value of said difference with a first angular value and deactivate the display of the images received from the image acquisition system on the display when the absolute value of the difference is greater than the first angular value.
