Abstract

An aircraft video camera mount provides for the removable, temporary attachment of a video camera and associated tilt and pan mechanisms to the upper end of the wing strut of a high wing airplane, or alternatively to a suitable strut of another aircraft type. The strut attachment bracket secures around the strut at one end, and may bolt through the strut at the opposite end using the existing wing tiedown bolt hole normally provided through the wing strut. The camera tilt, pan, and focal length are remotely operated by an operator in the aircraft. Both the electrical power and the operating systems for the camera are preferably portable and self contained, so they may be easily removed and quickly installed in the aircraft as the need arises, thus precluding need for FAA approvals for use of the existing aircraft electrical or other systems to operate the present camera system. The device is particularly suited to news operations where a dedicated aircraft is not available at all times, and/or where the additional expense of specialized aircraft (e.g., helicopters and blimps) is not justified. With the present device, an existing fixed wing aircraft may be used for charter or other operations when not needed for aerial video photography, due to the ease and quickness of installation and removal of the present camera equipment.
