Aviation Supplies & Academics, Inc. (ASA) develops and markets aviation supplies, software, and books for pilots, flight instructors, flight engineers, airline professionals, air traffic controllers, flight attendants, aviation technicians and enthusiasts. Established in 1947, ASA also provides ...
A piece of aircraft ground support equipment that includes a motor-generator and an air compressor. The GPU can be connected to an aircraft on the ground to supply electrical power and compressed air for system operation when the engines are not operating.
Industry:Aviation
A piece of canvas or plastic used to cover the floor or objects on the floor when walls and ceilings are being painted. The drop cloth prevents paint from dripping on areas where it should not be.
Industry:Aviation
A piece of electrical test equipment made up of a number of capacitors and selector switches. Any amount of capacitance needed in a circuit can be selected on the switches and the capacitance box inserted into the circuit where the capacitance is needed.
Industry:Aviation
A piece of electrical test equipment used to check armatures in DC motors and generators for open or shorted turns in the windings.
The armature to be tested is placed on the growler, and the AC power is turned on. The growler acts as the primary of a transformer and the armature as the secondary. A voltmeter is used to measure the voltage induced into the armature windings. A growler gets its name from the growling noise made when an armature is being tested.
Industry:Aviation
A piece of electronic equipment in a circuit that supplies input power to an output circuit or device.
Industry:Aviation
A piece of electronic equipment, used to stabilize the line voltage supplied to a piece of electrical or electronic equipment. Circuits in the line-voltage regulator increase the output voltage when the load current increases to prevent the output voltage dropping. And they decrease the voltage when the load decreases, preventing the output voltage rising above the regulated value.
Industry:Aviation
A piece of electronic navigation equipment which operates in the low- and medium-frequency bands.
ADF uses a directional loop antenna and a nondirectional sense antenna to find the direction to a radio station. This direction is shown on an instrument that looks much like the dial of a compass, with zero degrees representing the nose of the aircraft, rather than north. The needle on the ADF indicator shows the pilot the number of degrees clockwise from the nose of the aircraft to the radio station being received.
Industry:Aviation
A piece of electronic test equipment consisting of several precision resistors and selector switches. By connecting the resistance decade into a circuit and setting the selector switches in the proper positions, any required amount of resistance can be put into a circuit.
The resistance decade gets its name from the increments of resistance that can be selected. One switch can select resistances between 0.0 ohm and 0.9 ohm, in ten steps (a decade of steps) of 0.1 ohm each. The next switch can select resistances between 1.0 and 9.0 ohms. The other switches can select between
10.0 and 90.0, 100.0 and 900.0, and 1,000 and 9,000 ohms. With five switches, any amount of resistance between 0.1 ohm and 9,999.9 ohms can be put into a circuit.
Industry:Aviation
A piece of electronic test equipment that produces an electrical signal having a specified voltage, frequency, and waveform. Signal generators are used for troubleshooting and calibrating electrical and electronic equipment.
Industry:Aviation
A piece of electronic test equipment used to trace a signal through each stage of a piece of electronic equipment. Troubleshooting of malfunctioning equipment is simplified by comparing the waveform of the signal at each stage with the waveform that should be at that stage.
