Terms for subject Aviation (1897 entries)

shock wave	A region of abrupt change in pressure and density moving ahead of the aircraft as a wave front at or above the speed of sound
short takeoff and landing aircraft	An aircraft that, at some weight within its approved operating weight, is capable of operating from a STOL runway in compliance with the applicable STOL characteristics and airworthiness, operations, noise, and pollution standards
STOVL	short takeoff and vertical landing	'More
short-range clearance	A clearance issued to a departing IFR flight which authorizes IFR flight to a specific fix short of the destination while ATC facilities are coordinating and obtaining the complete clearance
shuttle procedure	A manoeuvre involving a descent or a climb in a pattern resembling a holding pattern
sidestep maneuver [s/c]	A visual maneuver [s/c] accomplished by a pilot at the completion of an instrument approach to permit a straight-in landing on a parallel runway not more than 1200 ft to either side of the runway to which the instrument approach was conducted
sierra creek	As in "up Sierra Creek without a paddle"
sierra hotel	Shit Hot, meaning "good"
sight picture	Term used to describe the position of the pipper at release
signal buster	Use maximum speed
signal charlie	Landing area is clear, commence approach
signal delta	Landing area is foul
significant meteorological information	Meteorological information issued concerning weather significant to the safety of aircraft. SIGMET advisories include the following: (a) active thunderstorm areas or lines of thunderstorms; (b) hurricanes, tropical storms; (c) moderate hail; (d) severe turbulence; (e) severe icing; (f) marked mountain waves; (g) widespread sandstorms and dust storms; (h) volcanic ash; (i) severe squall lines; (j) low-level wind shear; and (k) tornadoes or waterspouts.
significant point	An expression used to describe a NAVAID, a fix derived from a NAVAID, or a geographical location as expressed in latitude and longitude
significant point	A specified geographical location used in defining an ATS route or the flight path of an aircraft and for other navigation and ATS purposes
simulated approach	An instrument approach procedure (IAP) conducted in visual meteorological conditions (VMC) by an aircraft not on an IFR clearance
simulated flameout	A practice approach to a runway by a jet aircraft (normally military) at idle thrust. The approach may start at a relatively high altitude over a runway (high key) and may continue on a relatively high and wide downwind leg with a high rate of descent and a continuous turn to final.
Simulated kill on a friendly aircraft in ACBT	MORT
simultaneous converging instrument approaches	A procedure for conducting two or more simultaneous instrument approaches to converging runways
simultaneous ILS/MLS approach procedures	Approach procedures permitting instrument landing system (ILS) and microwave landing system (MLS) approaches to be conducted simultaneously at airports having parallel runways
