A natural magnetic iron oxide. Lodestones were discovered in ancient times and were the first devices to be used as a magnetic compass. The term lodestone comes from “leading stone.”
Industry:Aviation
A natural or synthetic material used to reduce the friction between parts in sliding contact with each other. Even parts that seem to be smooth actually have microscopically rough surfaces. When one rough surface slides over another, the surfaces lock and oppose the movement (this is called friction).
A lubricant between the surfaces holds them apart, and they slide over a film of the lubricant, rather than over each other. Lubricants may be in the form of a dry powder (powdered graphite or molybdenum), a liquid (oil), or a semi-liquid (grease).
Industry:Aviation
A natural wax applied to rib lacing cord used to attach the fabric to a fabric-covered aircraft. Beeswax protects the cord from moisture and keeps knots in the cord from slipping.
Industry:Aviation
A natural, translucent, solid or semisolid material, produced from the sap of certain trees or plants. Resins are soluble in organic solvents, such as ether, but are not soluble in water. Resins are used in the manufacture of varnishes, inks, and certain types of plastics.
Industry:Aviation
A naturally radioactive, metallic chemical element produced by bombarding bismuth or lead with neutrons. Polonium’s symbol is Po, its atomic number is 84, and the mass number of its most stable isotope is 209.
Industry:Aviation
A naturally radioactive, silvery, metallic chemical element used as a nuclear fuel. Plutonium’s symbol is Pu, its atomic number is 94, and the mass number of its most stable isotope is 244.
Industry:Aviation
A navaid used for nonprecision instrument approaches, with utility and accuracy comparable to a localizer but not a part of a complete ILS and not aligned with the runway.

A navaid used for nonprecision instrument approaches, with utility and accuracy comparable to a localizer. An LDA is not a part of a complete ILS and is not aligned with the runway.
Industry:Aviation
A navigation aid or intersection where an aircraft transitions between the domestic route structure and the ocean route structure.
Industry:Aviation
A navigation system that directs the pilot with an audible signal.
The four-course, low-frequency radio range is an aural radio range. The pilot flies down the center of the course line by positioning the aircraft so that a solid tone is heard. If the aircraft drifts to one side of the course line, the letter N (– .) in Morse code) is heard. If it drifts to the other side, the letter A (. –) is heard.
