A control tower that authorizes aircraft to land or takeoff at the airport controlled by the tower or to transit the Class D airspace.
The primary function of a nonapproach control tower is the sequencing of aircraft in the traffic pattern and on the landing area. Nonapproach control towers also separate aircraft operating under instrument flight rules clearances from approach controls and centers. They also provide ground control services to aircraft, vehicles, personnel, and equipment on the airport movement area.

A control used to cause certain types of equipment to operate at a desired speed. A governor has a sensor to measure the speed, a datum from which the speed is referenced, and a control to adjust the speed so it agrees with the datum.

A control valve in a fluid power system that reduces the pressure of a liquid or gas from a high value to a lower value that can be adjusted by the operator. After being set, the output pressure remains constant as the input pressure changes, within limits.

A control valve in a hydraulic system that allows the pilot to manually direct the output of the hydraulic pump back to the reservoir when no unit is being actuated.
Industry:Aviation
A controllable butterfly valve in the exhaust pipe of a reciprocating engine equipped with an exhaust-driven turbocharger. When the waste gate is open, the exhaust gases leave the engine through the exhaust pipe. But when it is closed, the gases must pass through the turbine that drives the turbocharger compressor.
By controlling the amount the waste gate is open, the speed of the turbocharger can be controlled, and this speed determines the manifold pressure in the engine.

A convenient unit used to measure the wavelength of light. One angstrom, or A, is one ten-millionth of a micron. This is 0.000 000 01 (10-8) centimeters. The wavelength of visible light extends from about 4,000 to 8,000 angstroms.

A coordinate representing the distance from the Y-, or vertical, axis in a plane Cartesian coordinate system.
The abscissa is measured along the X-, or horizontal, axis and the ordinate along the Y-, or vertical, axis.

A copper alloy containing tin and sometimes small amounts of zinc and phosphorus. Bronze’s low coefficient of friction makes it useful for bearings and bushings.
Industry:Aviation
A copper gasket used to form a leakproof seal between components that operate at a high temperature. The gasket is made of a hollow copper ring formed around a ring of asbestos.
When the component to be sealed is tightened down on the gasket, the asbestos compresses, and the surfaces press into the soft copper and form a leakproof seal.
