A transistor voltage regulator is not the same as a transistorized voltage regulator. In a transistorized voltage regulator, the alternator or generator output voltage is sensed by an electromagnetic relay. Only a small amount of current flows through the relay contacts, just the base current of an output transistor that controls the larger alternator field current.
transition area (air traffic control). Controlled airspace extending upward from 700 feet or more above the surface of the earth, when designated in conjunction with an airport for which an approved instrument approach procedure has been prescribed — or from 1,200 feet or more above the surface of the earth when designated in conjunction with airway route structures or segments. Unless otherwise limited, transition areas terminate at the base of the overlying controlled airspace.
Transition areas are designated to contain IFR operations in controlled airspace during portions of the terminal operation, and while transitioning between the terminal and en route environment.
transitional airspace (air traffic control). That portion of controlled airspace in which aircraft change from one phase of flight or one flight condition to another.
translational lift (helicopter operation). The additional lift produced by a helicopter rotor as the helicopter changes from hovering to forward flight. The lift produced by a helicopter rotor decreases as the helicopter rises vertically out of ground effect. But if the helicopter moves forward at an airspeed of somewhere around 15 to 20 miles per hour, the rotor system becomes more efficient in forcing the air downward, and the lift increases. This increased lift caused by the forward motion of the helicopter is called translational lift.
translucent. The condition of a material that diffuses the rays of light passing through it. This diffused light prevents objects being seen clearly when viewed through the material.
transmissometer (meteorology). An instrument system which shows the transmissibility of light through the atmosphere. Transmissibility may be translated either automatically or manually into visibility and/or runway visual range (RVR).
transmission line (electrical conductor). A conductor used to transfer electrical energy from its source to the load using it.
transmit (communications operation). To send information or data from one location to another. When a message is transmitted by radio, the information is changed into electromagnetic waves radiated out into space from the transmitting antenna. Radiated waves of electromagnetic energy are received by another antenna and changed back into the form of the original data.
transmitter (communications equipment). An electronic device that produces a radio-frequency carrier wave that can be modulated with information or data. The RF carrier produces electromagnetic energy that is radiated from an antenna.
transom (seaplane float component). The square stern of a seaplane float.
