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 ...
The action of certain chemicals that kill bacteria. Biocidal agents are used in turbine engine fuel to kill the bacteria and microbes living in water that condenses inside aircraft fuel tanks. If these microscopic organisms are not killed, they will multiply and form a scum that holds water against the aircraft skin and promotes corrosion.
Biocidal additives are also put in aircraft dope used on cotton or linen fabric to kill bacteria that can destroy either of these organic fabrics.
Industry:Aviation
The action that causes a liquid to climb the walls of a container or to be drawn up into extremely tiny tubes or between close-fitting parts.
The force of adhesion between the liquid and the solid wall of the container is greater than the force of cohesion between the molecules of the liquid. The stronger force of adhesion causes the liquid to try to spread out and wet the walls.
Capillary action causes a piece of blotting paper to pick up a liquid, and the lack of capillary action causes a drop of water to form into a ball on a waxed surface.
Industry:Aviation
The action which changes the pitch angle of helicopter rotor blades by rotating them about their feathering axis.
Industry:Aviation
The active element in an electrochemical cell that is reduced, or loses oxygen in the chemical action which causes electrons to flow.
Industry:Aviation
The actual amount of horsepower an engine-propeller combination transforms into thrust.
Industry:Aviation
The actual amount of water vapor present in a specific volume of air. If one cubic meter of air contains 100 grams of water, the absolute humidity of the air is 100 grams per cubic meter.
Industry:Aviation
The actual barometric (atmospheric) pressure measured at the observing station.
Industry:Aviation
The actual distance a propeller moves through the air in one revolution. Effective pitch is the difference between the geometric pitch of the propeller and the slip.
Industry:Aviation
The actual distance between a ground-based radar antenna and an airborne target.
Industry:Aviation
The actual distance between an aircraft and a ground radio facility. A distance measuring equipment (DME) indicator shows the slant-line distance between the aircraft and the ground station. Slant-line distance is the hypotenuse of a right triangle, with the altitude of the aircraft as one side, and the horizontal distance between the ground station and a point directly below the aircraft as the other side.
