The Rolleiflex SLX is a line of medium format single lens reflex cameras made by Rollei, in regular production starting from 1976.The SLX incorporated electronic autoexposure and motorized film transport, competing directly with the integrated-motor Hasselblad 500EL/M and effectively displacing the earlier Rolleiflex SL66 line, although the older camera continued to be produced.
The Fulton system in use The Fulton system in use from below. The Fulton surface-to-air recovery system (STARS), also known as Skyhook, is a system used by the Central Intelligence Agency (CIA), United States Air Force, and United States Navy for retrieving individuals on the ground using aircraft such as the MC-130E Combat Talon I and B-17 Flying Fortress.
Outdoor antennas provide up to a 15 dB gain in signal strength and 15-20 dB greater rejection of ghost signals in analog TV. [6] Combined with a signal increase of 14 dB due to height and 11 dB due to lack of attenuating building walls, an outdoor antenna can result in a signal strength increase of up to 40 dB at the TV receiver.
Amelia Earhart's Lockheed Model 10 Electra with the circular RDF aerial visible above the cockpit. A radio direction finder (RDF) is a device for finding the direction, or bearing, to a radio source. The act of measuring the direction is known as radio direction finding or sometimes simply direction finding (DF). Using two or more measurements ...
An officer programs a JPADS bundle with drop coordinates in preparation for a resupply mission. The steerable parachute or parafoil is called a "decelerator," and gives the JPADS system directional control throughout its descent by means of decelerator steering lines attached to the Autonomous Guidance Unit (AGU).
D-VOR/DME ground station DME antenna beside the DME transponder shelter. In aviation, distance measuring equipment (DME) is a radio navigation technology that measures the slant range (distance) between an aircraft and a ground station by timing the propagation delay of radio signals in the frequency band between 960 and 1215 megahertz (MHz).
An aerial tramway consists of one or two fixed cables (called track cables), one loop of cable (called a haulage rope), and one or two passenger or cargo cabins.The fixed cables provide support for the cabins while the haulage rope, by means of a grip, is solidly connected to the truck (the wheel set that rolls on the track cables).
In mid-1916, Boelcke codified his tactics in the Dicta Boelcke, which was the world's first tactical aerial combat manual for an air force. [ 2 ] During early 1916, Boelcke wrote a brochure entitled "Experiences of Air Fighting", giving tips for attacking any one of three types of opposing aircraft.
