Ice that forms on an aircraft flying through freezing rain or other visible moisture when the air temperature is in the freezing range (between 0° and –15°C). Impact ice forms on the leading edges of the wing and tail surfaces and disturbs the smooth flow of air over these surfaces. Impact ice also forms on the engine inlet air filters and can stop an engine functioning unless inlet air is taken from an alternate source.
Impact ice forming on the inlet air duct of a jet engine can break off and be pulled through the engine, causing severe damage to the compressor blades.

Ice that forms when large drops of water strike a surface whose temperature is below freezing. Glaze ice is clear and heavy.
Industry:Aviation
Identification of each of the external connections of an integrated circuit chip.
Industry:Aviation
Ignition of the fuel-air mixture inside the cylinder of an engine before the normal spark occurs. Preignition can be caused by an incandescent piece of carbon or by any other sharp edge or point inside the cylinder that gets red-hot.
Industry:Aviation
Imaginary lines on the surface of the earth parallel to the equator. Parallels of latitude are used as north and south reference lines for map making and navigation. The equator is the 0° parallel of latitude, the geographic north pole is located at 90° north latitude, and the geographic south pole is located at 90° south latitude.
Industry:Aviation
Improper operation of the power control lever of a gas turbine engine in which the control is moved forward too quickly to allow the engine to accelerate as it should. There is danger of a rich flameout if the fuel is metered into the engine before the compressor is able to pull enough air into the engine to furnish the correct fuel-air mixture ratio.

In nondestructive inspection, any interruption in the normal physical structure or configuration of a part. A discontinuity may or may not affect the usefulness of a part.

In radio communications, to modulate means to change some characteristic, such as amplitude, frequency, or phase of an alternating current wave.
A radio-frequency (RF) wave having a constant amplitude can be amplitude modulated (AM) by an audio-frequency (AF) voltage changing the amplitude of the RF wave in the same way the amplitude of the AF signal varies. The changes in voltage of the modulated RF wave can be used to produce a varying AF voltage. This process is called demodulation.

Inactive or inert. In the electrochemical series of metals, the metal in a combination that does not corrode is the more noble.
