induce /.ndjus/ verb to bring about, to cause to happen . If a coil carrying a changing current is placed near another coil, the changing magnetic field cuts the other coil and induces a voltage in it. . Unequal deposits on moving parts can induce severe vibra-tion especially on propellers and heli-copter rotors.
induced drag /.ndjust dr/
noun part of total drag, created by lift .
There are two basic types of drag, induced drag and parasite drag.
COMMENT: Induced drag is created when high-pressure air below a wing rotates around the tip to the low-pressure area above and increases as airspeed decreases and angle of attack increases.
inductance /.ndkt.ns/ noun a
measure of a conductor’s ability to bring a voltage into itself when carrying a changing current, e.g. during short times when the circuit is switched on or off . At low frequencies, the rate of col-lapse of the magnetic field will be slow and the inductance will be low.

induction /.ndk..n/ noun 1. the
process by which the fuel/air mixture is drawn into the cylinders of an internal combustion engine . The four strokes of the engine are induction, compression, combustion and exhaust. 2. the produc-tion of electrical current in a conductor by a change of magnetic field . A trans-former is a static device that changes the amplitude or phase of an alternat-ing voltage or current by electro-mag-netic induction.
inductive /.ndkt.v/ adjective refer-
ring to the production of electrical cur-rent in a conductor by a change of mag-netic field . One side effect of low frequency in an inductive circuit is that excess heat may be produced.
inductor /.ndkt./ noun a compo-nent in the ignition system that pro-duces electrical current in itself by a change of magnetic field
inert /.nt/ adjective not reacting with other substance
inert gas /.nt s/ noun a gas that does not react with other substances .
Inert gases, dust, smoke, salt, volcanic ash, oxygen and nitrogen together con-stitute 99% of the atmosphere. (NOTE: The inert gases include helium, neon, argon, krypton and xenon.)
inertia /.n../ noun the tendency of a body at rest to stay at rest or of a mov-ing body to continue moving in a straight line unless acted on by an out-side force . Inertia switches operate automatically when a particular g (acceleration due to Earth’s gravity) loading occurs.
inertial /.n.(.)l/ adjective referring to inertia
inertial navigation system /. n.(.)l nv.e..(.)n s.st.m/ noun a navigation system which calcu-lates aircraft position by comparing measurements of acceleration with stored data, using gyros rather than radios. Abbreviation INS
inferential /.nf.ren.(.)l/ adjective
obtained by deduction . The inferential method of ice detection is used in flight trials for aircraft certification.
inflammable /.nflm.b(.)l/ adjec-tive easily set on fire . Petrol is an inflammable liquid. (NOTE: Flammable and inflammable mean the same thing.) . highly inflammable very eas-ily set on fire, and therefore hazardous
