Aviation Supplies & Academics, Inc. (ASA) develops and markets aviation supplies, software, and books for pilots, flight instructors, flight engineers, airline professionals, air traffic controllers, flight attendants, aviation technicians and enthusiasts. Established in 1947, ASA also provides ...
A monitor that provides air traffic controllers with high-precision secondary surveillance data for aircraft on final approach to closely spaced parallel runways. High-resolution color monitoring displays present surveillance track data to controllers, along with detailed maps depicting approaches and the no transgression zone.
Industry:Aviation
A monoplane in which the wing is mounted near the top of the fuselage, but not on the top.
The classifications of a monoplane with regard to the placement of the wing are: low-wing, midwing, shoulder-wing, high-wing, and parasol-wing.
Industry:Aviation
A movable marker on a flight instrument that may be set to reference a particular indication of the instrument. A bug on the airspeed indicator can be set to reference a particular airspeed for the pilot or the airspeed-hold function of an autopilot to hold.
A bug on the horizontal situation indicator can be used to direct the automatic pilot to turn to and hold the heading on which the bug is set.
Industry:Aviation
A movable primary control surface on an airplane designed in such a way that aerodynamic forces help the pilot move the surface.
A portion of the surface, called the balance area, extends ahead of the hinge line, and the force of the air pushing on this balance area aids the pilot in moving the surface.
Industry:Aviation
A multibarrel pressure carburetor used on large radial and V-engines. The fuel is metered on the basis of the mass of the air flowing into the engine and is sprayed under pressure into the eye, or center, of the internal supercharger impeller.
Industry:Aviation
A multibladed circular saw having two blades mounted on an arbor with a chipper between them. A dado head is used to cut a flat-bottomed groove in wood.
Industry:Aviation
A multicontact switch with the contacts arranged around the outside of a circular wafer. A shaft through the center of the wafer is rotated by a knob to connect a center contact, or wiper, to any one of the contacts around the wafer. Several wafers can be stacked together with their center contacts rotated by the same shaft.
Industry:Aviation
A multiple screw thread in which three threads are cut parallel to each other. The starting point of each thread is 120° from the starting point of the others. The lead, or the distance the screw moves forward in one revolution, is three times the pitch (the distance between the threads adjacent to each other).
Industry:Aviation
A multi-pole switch used to connect a single conductor to any one of several other conductors.
Industry:Aviation
A multi-turn potentiometer, or variable resistor. The resistance element is made in the form of a spiral, or helix, and the wiper is moved over the element by turning a multi-turn screw. Most helical potentiometers require ten turns of the screw to move the wiper from one end of the resistance element to the other.
