A report of meteorological phenomena encountered by aircraft in flight.
Industry:Aviation
A report over a known location as transmitted by an aircraft to ATC.
Industry:Aviation
A request by ATC for a pilot to activate the radar beacon transponder identification feature.
Industry:Aviation
A reserve, or substitute, system that can be put into effect if the main or primary system should fail.
Industry:Aviation
A reservoir used to store a liquid. The container for the mercury in a mercury barometer is called a cistern.
Industry:Aviation
A resistor in an electrical circuit used to drop voltage. For example, if a 12-volt light bulb is used in a 24-volt electrical system, a dropping resistor must be installed in series with the bulb to drop 12 volts. This allows only 12 volts across the bulb.
Industry:Aviation
A resistor in series with a voltmeter mechanism used to extend the range of the basic meter or to allow a single meter to measure several ranges of voltage.
Industry:Aviation
A resistor installed in a shielded spark plug between the ignition lead terminal and the center electrode. The capacitance in the shielded ignition lead stores enough energy to keep the spark flowing across the gap long enough to erode the electrodes. The resistor decreases the duration of the spark and thus minimizes electron erosion.
Industry:Aviation
A resistor made of a mixture of carbon and an insulating material. The mixture is molded inside a protective insulation with a wire lead extending radially from each end.
The ohmic value of the resistor is determined by the percentage of insulating material in the mixture, and the physical size determines the amount of heat the resistor can dissipate. The resistance, in ohms, is marked by a series of colored bands around one end.
Industry:Aviation
A resistor used to limit the maximum amount of current allowed to flow in a circuit.
A current-limiting resistor is often installed in series with a fuse to limit the maximum amount of current that can flow before the fuse heats up enough to melt and open the circuit.
