Abstract

An aircraft is equipped with a rearwardly pointed television camera connected to an electronic receiver situated in front of the pilot. The image provided by the camera at the receiver appears in mirror reversed inverted or symmetrically opposite position, in order that the maneuvers required for rearward firing can be carried out by the common piloting reflexes for forward firing.

Claims

1. Method of sighting for rearward firing on a combat aircraft carrying a rearwardly directed weapon arranged thereon for firing along an axis which is brought into firing alignment with a rearwardly positioned target by maneuvering the flight direction of the aircraft, said combat aircraft being equipped with a television camera pointing towards the rear and an electronic receiver situated in front of the pilot, said method comprising the step of connecting the output of said camera to the input of said receiver in such a way that the image delivered by the camera appears on the receiver in a position symmetrically opposite to the true rearward position of the target in relation to said firing axis, whereby the firing maneuvers needed to be carried out by the pilot to aim the aircraft at a rearwardly located object can be performed in accordance with the normal piloting reflexes for forward aiming.

2. Method as claimed in claim 1, comprising the further steps of generating a sighting reticle to be formed on the electronic receiver and superposing said reticle upon the image received at the receiver from the camera.

3. Method as claimed in claim 1, comprising the further step of optionally switching the connection between the camera and the receiver to restore the TV image to "normal" relation to the actual rear view.
