Standard hardware items such as bolts, nuts, screws, and rivets made according to standards established by the Air Force and Navy. AN hardware is approved for use in both military and civilian aircraft.
Industry:Aviation
Standardized graphic symbols that have been agreed upon as representing various components in electrical schematic diagrams.
Industry:Aviation
Static electricity that exists between clouds and between clouds and the surface of the earth.
Industry:Aviation
Station pressure (the barometric pressure at the location the reading is taken) which has been corrected for the height of the station above sea level.
When the altimeter setting is entered into the barometric pressure window of an altimeter, the instrument will indicate its height above mean, or average, sea level. This is called indicated altitude.
Industry:Aviation
Stationary airfoils at the discharge end of an axial-flow compressor. As the air passes through the compressor, the rotating vanes give the air a swirling, or rotational, motion. The exit guide vanes straighten it out so the air leaves the compressor in an axial direction, parallel to the length of the engine.
Industry:Aviation
Stationary vanes located in front of the first stage of the compressor in an aircraft gas turbine engine. The purpose of the inlet guide vanes is to direct the air into the first stage of the compressor at the proper angle for the most efficient compression. Most inlet guide vanes are fixed, but in some engines, their angle can be changed by hydraulic actuators controlled by the fuel control unit. Movable guide vanes direct the air into the compressor at the correct angle as the operating conditions inside the engine change.
Industry:Aviation
Stationary voltage waves existing on an antenna or transmission line that are caused by two waves, identical in amplitude and frequency, but traveling in opposite directions along the conductor.
“Stand by” (air traffic control). A phrase used by ATC meaning that the controller or pilot must pause for a few seconds, usually to attend to other duties of a higher priority. It also means to wait, as in “stand by for clearance.” The phrase “stand by” is neither an approval nor denial.
Industry:Aviation
Steel aircraft control cable made of either 7 or 19 strands of solid wire. Nonflexible cable can be used only for installations in which the cable does not pass over pulleys.
Industry:Aviation
Steel alloyed with nickel and chromium, to increase its resistance to corrosion or rust. Corrosion-resistant steel is also called stainless steel.
