  • Patent number: 4218702
    Abstract: A method of remote control of an aircraft video system and means especially adapted for carrying out said method. An aircraft carries a technical container comprising at least one TV camera monitored by a TV screen and remotely controlled by a control box in the pilot's cockpit. On the ground there are disposed an orientable aerial, a receiver, a remote-control box for the aerial, a VHF microphone and a magnetoscope.By using this system an operator in the aircraft can both keep stability of the image transmitted to the ground and monitor it by enlargement on the monitor TV screen through instinctive reaction upon the remote-control box in the cockpit.The operator can act on his own initiative or on instructions being received from the ground or possibly by way of a duplex system.
