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 ...
High-carbon steel, a steel containing more than 0.5% carbon, that has been hardened and tempered to give it the maximum amount of elasticity, or the ability to return to its original shape after it has been deflected. Spring steel is hardened and then tempered to remove part of the brittleness by reheating until it turns a uniform dark blue.
Industry:Aviation
High-intensity lights located along the approach path at the end of an instrument runway.
Approach lights aid the pilot in transitioning from instrument flight conditions to visual conditions at the end of an instrument approach.
Industry:Aviation
High-strength steel wires that connect diagonally fore and aft across the cabane struts of an biplane. Adjustment of the length of the stagger wires determines the fore-and-aft relationship of the upper wing to the lower wing.
Industry:Aviation
High-strength structural materials made by encapsulating a fibrous material in a resin matrix. Advanced composites have superior strength and stiffness and are light-weight. Kevlar and graphite fibers encapsulated in an epoxy matrix are widely used in modern aircraft construction.
Industry:Aviation
Hollow blades on the turbine wheel of certain high-power gas turbine engines. These blades are cooled by compressor bleed air flowing through them.
Industry:Aviation
Hollow, microscopic-size spheres of hardened phenolic resin. Microballoons add body with very little weight to a resin used as a filler. The resin is mixed with the proper amount of accelerator, and then sufficient microballoons are added to give the resin enough body to be an effective filler.
Industry:Aviation
Horizontal structural members between the two floats mounted on an aircraft.

Ice crystal deposits formed by sublimation when the temperature and dew point are below freezing.
Industry:Aviation
Ice forming on an aircraft. Classifications of icing are: clear, rime, and glaze.
Industry:Aviation
Ice that forms inside the throat of a carburetor installed on an aircraft reciprocating engine. When air flows through the carburetor venturi, it speeds up, and both its pressure and temperature drop. When liquid fuel is discharged into the throat of the venturi, it vaporizes, and this change of state drops its temperature.
When the temperature of the air is low enough, moisture in the air condenses out and freezes. It is possible for carburetor ice to build up inside the venturi and restrict the air flowing into the engine enough to cause the engine to stop. Carburetor ice is normally prevented by heating the air before it enters the carburetor.
