A type of electronic filter that passes, with little opposition, alternating current above a certain frequency. A high-pass filter blocks direct current, and blocks or reduces the amplitude of all ...

very-high-frequency omnirange navigation equipment (VOR)

Aviation; Aeronautics

A type of electronic navigation equipment in which the instrument in the cockpit identifies the radial, or line from the VOR station measured in degrees clockwise from magnetic north, along which the ...

long range navigation (LORAN)

Aviation; Aeronautics

A type of electronic navigation system, used by aircraft and ships. The abbreviated name LORAN comes from LOng RAnge Navigation. LORAN is a low-frequency pulse navigation system based on latitude and ...

relaxation oscillator

Aviation; Aeronautics

A type of electronic oscillator that changes direct current into pulsating DC with a sawtooth waveform. A capacitor is charged through a resistor to produce a slow rise in voltage. At a specified ...

monostable multivibrator

Aviation; Aeronautics

A type of electronic oscillator that has two conditions. It is stable in one of these conditions and tries to remain in this condition, but a special signal can cause it to shift to the other. As ...

Very signal

Aviation; Aeronautics

A type of emergency light signal used by ships and aircraft. A special pistol, a Very pistol, fires a cartridge that looks much like a shotgun cartridge. The cartridge sends up a ball of white or ...

synthetic oil
