autoclave molding. A method of molding laminated reinforced plastic components. The reinforced resin is laid up over a form having the required shape and is covered with a vacuum bag. Air is pumped out of the bag, and the entire assembly is placed in an autoclave where the temperature is raised and the air pressure is increased. The pressure inside the autoclave forces the plastic resin into the reinforcing material and forces out any air left in the resin. autofeather. The portion of a propeller control system which causes the propeller to feather automatically if the engine on which it is mounted is shut down in flight. autogiro. A heavier-than-air rotor-wing aircraft that is sustained in the air by rotors turned by aerodynamic forces rather than by engine power. When the name Autogiro is spelled with a capital A, it refers to a specific series of machines built by Juan de la Cierva or his followers. autoignition system. A system on a turbine engine that automatically energizes the igniters to provide a relight if the engine should flame out. autoland approach (air traffic control). A precision instrument approach to touchdown and, in some cases, through the landing rollout. An autoland approach is performed by the aircraft autopilot which is receiving position information and/or steering commands from onboard navigation equipment. auto lean (reciprocating engine fuel-air mixture). A fuel-air mixture whose ratio is kept constant in the lean range by an automatic mixture control in the carburetor or fuel injection system. automated mutual-assistance vessel rescue system (air traffic control). A facility which can deliver, in a matter of minutes, a surface picture (SURPIC) of vessels in the area of a potential or actual search and rescue incident, including their predicted positions and their characteristics. automated radar terminal systems. See ARTS. automatic. An operation with the ability to perform by itself. An automatic operation has all the necessary signals built into it so that it performs its function without any external decisions having to be made. automatic adjuster (aircraft brake component). A subsystem in an aircraft disk brake that compensates for disk or lining wear. Each time the brakes are applied, the automatic adjuster is reset for zero clearance, and when the brakes are released, the clearance between the disks or the disk and lining is returned to a preset value. automatic altitude reporting. A function of a radar beacon transponder that responds to Mode C interrogations by transmitting the aircraft’s altitude in 100-foot increments. automatic direction finder. See ADF. automatic flight control system. See AFCS. |
