Pilot/Controller Glossary 8/5/04TRANSFERRING CONTROLLER− A controller/facility transferring control of an aircraft to anothercontroller/facility.(See ICAO term TRANSFERRINGUNIT/CONTROLLER.)TRANSFERRING FACILITY−(See TRANSFERRING CONTROLLER.)TRANSFERRING UNIT/CONTROLLER [ICAO]−Air traffic control unit/air traffic controller in theprocess of transferring the responsibility for providingair traffic control service to an aircraft to the nextair traffic control unit/air traffic controller along theroute of flight.Note: See definition of accepting unit/controller.TRANSITION−a. The general term that describes the change fromone phase of flight or flight condition to another; e.g.,transition from en route flight to the approach ortransition from instrument flight to visual flight.b. A published procedure (DP Transition) used toconnect the basic DP to one of several en routeairways/jet routes, or a published procedure (STARTransition) used to connect one of several en routeairways/jet routes to the basic STAR.(Refer to DP/STAR Charts.)TRANSITION POINT− A point at an adaptednumber of miles from the vertex at which an arrivalaircraft would normally commence descent from itsen route altitude. This is the first fix adapted on thearrival speed segments.TRANSITION WAYPOINT− The waypoint thatdefines the beginning of a runway or en routetransition on an RNAV SID or STAR.TRANSITIONAL AIRSPACE− That portion ofcontrolled airspace wherein aircraft change from onephase of flight or flight condition to another.TRANSMISSOMETER− An apparatus used to determinevisibility by measuring the transmission oflight through the atmosphere. It is the measurementsource for determining runway visual range (RVR)and runway visibility value (RVV).(See VISIBILITY.)TRANSMITTING IN THE BLIND− A transmissionfrom one station to other stations incircumstances where two-way communicationcannot be established, but where it is believed that thecalled stations may be able to receive the transmission.TRANSPONDER− The airborne radar beacon receiver/transmitterportion of the Air Traffic ControlRadar Beacon System (ATCRBS) which automaticallyreceives radio signals from interrogators on theground, and selectively replies with a specific replypulse or pulse group only to those interrogationsbeing received on the mode to which it is set torespond.(See INTERROGATOR.)(See ICAO term TRANSPONDER.)(Refer to AIM.)TRANSPONDER [ICAO]− A receiver/transmitterwhich will generate a reply signal upon properinterrogation; the interrogation and reply being ondifferent frequencies.TRANSPONDER CODES−(See CODES.)TRIAL PLAN− A proposed amendment whichutilizes automation to analyze and display potentialconflicts along the predicted trajectory of the selectedaircraft.TRSA−(See TERMINAL RADAR SERVICE AREA.)TSD−(See TRAFFIC SITUATION DISPLAY.)TURBOJET AIRCRAFT− An aircraft having a jetengine in which the energy of the jet operates aturbine which in turn operates the air compressor.TURBOPROP AIRCRAFT− An aircraft having a jetengine in which the energy of the jet operates aturbine which drives the propeller.TURN ANTICIPATION− (maneuver anticipation).TVOR−(See TERMINAL-VERY HIGH FREQUENCYOMNIDIRECTIONAL RANGE STATION.)TWEB−(See TRANSCRIBED WEATHER BROADCAST.)TWO-WAY RADIO COMMUNICATIONS FAIL-URE−(See LOST COMMUNICATIONS.)PCG T−6
