An acoustic transducer. A microphone changes sound pressure variations into electrical signals.
Industry:Aviation
An acoustic underwater detection system that listens for the sound produced by underwater objects. Passive sonar does not transmit signals to search for submerged objects.
Industry:Aviation
An acrobatic flight maneuver in which an aircraft spins in an inverted attitude.
Industry:Aviation
An acronym used by a pilot for a pretakeoff check to be sure that none of the most important items are missed:
: G — Gasoline (The correct fuel tank should be selected for takeoff.)
: U — Undercarriage (The landing gear selector should be in the down position and the indicator lights show that the gear is locked down.)
: M — Mixture (The mixture control should be in the correct position for takeoff.)
: P — Propeller (The propeller pitch control should be in the low-pitch, high RPM position for takeoff.)
Industry:Aviation
An action taken to transfer the radar identification of an aircraft from one controller to another if the aircraft will enter the receiving controller’s airspace and radio communications with the aircraft will be transferred.
Industry:Aviation
An active semiconductor device with three electrodes: an emitter, a collector, and a base. A large flow of electrons between the emitter and the collector is controlled by a much smaller flow of electrons between the emitter and the base. Transistors are physically small, require almost no power for their operation, are extremely rugged, and are low in cost.
Industry:Aviation
An additive used in aviation gasoline to improve its antidetonation characteristics. Tetraethyl lead, Pb(C2H5)4, is a heavy, oily, poisonous liquid mixed with the gasoline at the refinery. Tetraethyl lead increases the critical pressure and temperature of the fuel.
Industry:Aviation
An additive used to produce a multiviscosity lubricating oil. The polymer additive expands as temperature increases and contracts as the temperature decreases. VI improvers cause the viscosity to increase as the oil becomes hot and decrease when it becomes cold.
Industry:Aviation
An adhesive packaged in two containers and mixed just before it is used. A two-part adhesive consists of resin and an accelerator to speed up the curing action of the resin.
Industry:Aviation
