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 sloping channel used to allow objects or materials to slide from one level to a lower level.
Industry:Aviation
A slotted opening in a structure, used for the passage of cooling air. Louvers are often fitted with vanes to control the amount of air flowing through them.
Industry:Aviation
A slow-acting electrical relay in which there is a measurable delay between the time current is applied to the relay coil and the time the relay contacts close. A time-delay relay is called a slow-closing or a slow-opening relay.
Industry:Aviation
A slow-drying thinner used with certain types of lacquer or dope to slow the evaporation of the solvents.
When the solvents evaporate too rapidly, the evaporation drops the temperature of the surrounding air enough to cause moisture to condense out of the air. This moisture causes the dope or lacquer to blush.
Industry:Aviation
A small adjustable tab on a primary control surface of an airplane. The tab is automatically actuated in such a way it moves in the direction opposite to the direction the control surface on which it is mounted moves.
Air flowing over the balance tab produces a force on the control surface that reduces the amount of force needed by the pilot to move the surface.
Industry:Aviation
A small alternating current generator, mounted on and driven from the tachometer drive pad on an engine. The frequency of the AC produced by the tachometer generator is proportional to the speed of the engine.
Industry:Aviation
A small auxiliary tab, set into the trailing edge of a primary control surface on a high-speed airplane. The control surface is attached to the control horn through a torsion rod. Under normal flight loads, the spring tab remains fixed to the control surface and serves no purpose. But, when the air loads are high and a large amount of force is needed to move the control surface, the torsion rod twists, and the control rod moves the spring tab in a direction opposite to that of the surface on which it is mounted. It then acts as a servo tab and aids the pilot in moving the control surface.
Industry:Aviation
A small card mounted near the magnetic compass to show the pilot the amount of deviation error for each heading.
Industry:Aviation
A small central processing unit (CPU) for a microcomputer. A microprocessor is built into a single integrated circuit chip, and it includes the arithmetic-logic unit (ALU), the control unit, and the necessary registers that serve as the computer memory.
Industry:Aviation
A small coil in series with the collector of a transistor in an oscillator circuit. The tickler coil is part of a feedback circuit. Current flowing through the tickler coil induces a voltage in an inductor in the base circuit.
