A duct, or passage, whose cross-sectional area increases in the direction of fluid flow. When fluid flows through a divergent duct at a subsonic rate, its velocity decreases, and its pressure increases.
Industry:Aviation
A ductile, malleable, reddish-brown, metallic chemical element. Copper’s symbol is Cu, its atomic number is 29, and its atomic weight is 63.546. Copper is one of our most important nonferrous metals. It is heavy, ductile, and malleable and has excellent electrical and thermal conductivity.
Copper is used as a pure metal and as an alloy for other metals. One of copper’s widest uses is in the manufacture of electrical wire.
Industry:Aviation
A dull surface which forms on some types of metal when oxygen in the air changes some of the metal into its oxides. Polished aluminum, for example, tarnishes, or turns dull, when aluminum oxide forms on its surface.
Industry:Aviation
A duplicate of an object which is like the original object in all ways except that one side is the reverse of the other: the left side is on the right, and the right side is on the left. This term is taken from the image we see formed in a mirror. When we face a mirror, the image we see has its right side on the left and its left side on the right.

A dye used with silica-gel in a dehydrator to indicate the presence of moisture.
When cobalt chloride is dry, it is deep blue in color, but when it absorbs water, it turns pink. If a dehydrator element is blue, the component it protects is dry. But if moisture gets into it, the silica-gel absorbs some of the moisture, and the cobalt chloride turns pink.
Industry:Aviation
A dynamic input parameter specifying the number of arriving aircraft which an airport or airspace can accept from the ARTCC per hour.
The AAR is used to calculate the desired interval between successive arrival aircraft.
Industry:Aviation
A dynamic value found by dividing the change in plate voltage by the change in plate current caused by the voltage change. No conditions other than the voltage and current are allowed to change when making this measurement.
Industry:Aviation
A fabric tape in which the threads run at an angle, usually 45°, to the length of the tape. Bias-cut tape is often used as a surface tape when covering an aircraft, because it can be stretched around a compound curve without wrinkling.
Industry:Aviation
A fabric tape used to cover edges of metal sheets, screw and rivet heads, and any surface discontinuity on an aircraft structure that is to be covered by aircraft fabric. Covering these parts with chafing tape prevents their rubbing holes in the fabric.
Industry:Aviation
A fabric tube made of loosely woven cotton thread. Cotton braid is used to encase bungee shock cord and certain types of rubber hose.
