A handy mathematical tool in which very large and very small numbers are changed to numbers between 1 and 10 with a superscript (exponent) to show the number of places to move the decimal point. Powers of ten is another name for scientific notation. Numbers greater than 1 have a positive exponent, and numbers smaller than 1 have a negative exponent.
: 100 = 1
: 101 = 10
: 102 = 100
: 103 = 1,000
: 104 = 10,000
: 105 = 100,000
: 106 = 1,000,000

A handy tool for rough troubleshooting an aircraft electrical system. A bug light has a flashlight bulb and batteries to check for continuity in the aircraft wiring, and a bulb of the proper voltage to check for the presence of voltage in the part of the system being examined.

A hard steel, coil-spring retainer used to hold a rivet set in a pneumatic rivet gun.
A beehive spring, which gets its name from its shape, screws onto the end of the rivet gun and allows the rivet set to move back and forth, but prevents it being driven out of the gun.
Industry:Aviation
A hard, airtight oxide coating deposited on the surface of aluminum or magnesium alloys. Both aluminum and magnesium alloys corrode easily when their surfaces are covered with an electrolyte such as water or moist air. To protect against corrosion, an inhibitive oxide film is deposited on the surface to keep all oxygen and moisture away from the metal. Inhibitive films may be deposited by either chemical or electrolytic action.

A hard, brittle, lustrous, silvery-white metallic chemical element. Antimony’s symbol is Sb, its atomic number is 51, and its atomic weight is 121.75. Antimony expands as it changes from its molten state into a solid state, and because of this, it is an important alloying element with lead for type metal and for making lead-acid storage batteries.

A hard, brittle, metallic chemical element. Cobalt’s symbol is Co, its atomic number is 27, and its atomic weight is 58.93. Cobalt is used as an alloying element in permanent magnets.
Industry:Aviation
A hard, durable finish for wood that is to be kept outdoors where it is exposed to the weather. Spar varnish is made of a resin mixed with drying oils and thinners, and it is brushed on the surface to be protected. When the drying oils cure, they leave a hard, protective resin film on the wood. Spar varnish is much more durable than spirit varnish.
Industry:Aviation
A hard, glass-like coating that forms on the brake disk surface. The friction caused by the glazed surface is not uniform, and when the brakes are applied, they grab and release at such a high rate that they chatter or squeal. The glazed surface must be removed from a disk for the braking to be effective.
Industry:Aviation
A hard, gray, metallic chemical element. Molybdenum’s symbol is Mo, its atomic number is 42, and its atomic weight is 95.95. One of the main uses of molybdenum is as an alloying agent for steel. Molybdenum increases the toughness of steel and makes it easy to weld and machine.
Industry:Aviation
A hard, gray, or steel-blue metallic chemical element. Tantalum’s symbol is Ta, its atomic number is 73, and its atomic weight is 180.948. Tantalum is used in the manufacture of light bulb filaments, and tantalum oxide is used in electrolytic capacitors.
