A special drill used for cutting holes in graphite structural materials. The flat surfaces of the drill end allow ample room for the drill dust to leave the hole so it will not abrade the sides of the hole and increase its diameter.
Industry:Aviation
A special drill used for drilling cured Kevlar-reinforced composite materials. The tendency of Kevlar fibers to pull and stretch when they are cut with a drill is minimized by using a brad-point drill.
Industry:Aviation
A special electrical switch enclosed in a housing that prevents the sparks which occur when the contacts separate from igniting any explosive gases that may be on the outside of the housing.
Industry:Aviation
A special electron tube used to produce high-power electromagnetic energy in the ultrahigh and superhigh frequency ranges. Magnetron tubes are used in airborne radar equipment.
Industry:Aviation
A special field of medicine that establishes standards of physical fitness for airmen.
Industry:Aviation
A special flight permit issued by the Federal Aviation Administration that allows an unlicensed aircraft to be flown from its present location to another location where it can be repaired, inspected, or otherwise prepared for licensing.

Industry:Aviation
A special gage that measures the radius between the valve head and the valve stem. If this radius is greater than that of the gage, the valve has been stretched and it must be discarded.
Industry:Aviation
A special gas-filled electron tube. The tube, in series with a resistor, is placed across the output of a DC power supply. The gas in the tube ionizes when a specific voltage is placed across it, and when the gas ionizes, electrons flow through it with very little opposition. The voltage drop across the regulator tube remains constant as the load current changes.
Industry:Aviation
A special high-current rectifier tube. In each cycle of operation of an ignitron tube, an ignitor dips into a pool of mercury, and as it is withdrawn, it creates an arc which produces ionized mercury vapor that conducts a large amount of current.
