2/19/04Pilot/Controller GlossaryTTACAN−(See TACTICAL AIR NAVIGATION.)TACAN-ONLY AIRCRAFT− An aircraft, normallymilitary, possessing TACAN with DME but no VORnavigational system capability. Clearances mustspecify TACAN or VORTAC fixes and approaches.TACTICAL AIR NAVIGATION− An ultra-highfrequency electronic rho-theta air navigation aidwhich provides suitably equipped aircraft a continuousindication of bearing and distance to the TACANstation.(See VORTAC.)(Refer to AIM.)TAILWIND− Any wind more than 90 degrees to thelongitudinal axis of the runway. The magneticdirection of the runway shall be used as the basis fordetermining the longitudinal axis.TAKEOFF AREA−(See LANDING AREA.)TAKE-OFF DISTANCE AVAILABLE [ICAO]− Thelength of the take-off run available plus the length ofthe clearway, if provided.TAKE-OFF RUN AVAILABLE [ICAO]− The lengthof runway declared available and suitable for theground run of an aeroplane take-off.TARGET− The indication shown on a radar displayresulting from a primary radar return or a radarbeacon reply.(See RADAR.)(See TARGET SYMBOL.)(See ICAO term TARGET.)TARGET [ICAO]− In radar:a. Generally, any discrete object which reflects orretransmits energy back to the radar equipment.b. Specifically, an object of radar search orsurveillance.TARGET RESOLUTION− A process to ensure thatcorrelated radar targets do not touch. Target resolutionshall be applied as follows:a. Between the edges of two primary targets or theedges of the ASR-9 primary target symbol.b. Between the end of the beacon control slash andthe edge of a primary target.c. Between the ends of two beacon control slashes.Note 1: MANDATORY TRAFFIC ADVISORIESAND SAFETY ALERTS SHALL BE ISSUEDWHEN THIS PROCEDURE IS USED.Note 2: This procedure shall not be providedutilizing mosaic radar systems.TARGET SYMBOL− A computer-generated indicationshown on a radar display resulting from aprimary radar return or a radar beacon reply.TAXI− The movement of an airplane under its ownpower on the surface of an airport (14 CFR Section135.100 [Note]). Also, it describes the surfacemovement of helicopters equipped with wheels.(See AIR TAXI.)(See HOVER TAXI.)(Refer to 14 CFR Section 135.100.)(Refer to AIM.)TAXI PATTERNS− Patterns established to illustratethe desired flow of ground traffic for the differentrunways or airport areas available for use.TCAS−(See TRAFFIC ALERT AND COLLISIONAVOIDANCE SYSTEM.)TCH−(See THRESHOLD CROSSING HEIGHT.)TCLT−(See TENTATIVE CALCULATED LANDINGTIME.)TDZE−(See TOUCHDOWN ZONE ELEVATION.)TELEPHONE INFORMATION BRIEFING SER-VICE− A continuous telephone recording of meteorologicaland/or aeronautical information.(Refer to AIM.)TENTATIVE CALCULATED LANDING TIME− Aprojected time calculated for adapted vertex for eacharrival aircraft based upon runway configuration,airport acceptance rate, airport arrival delay period,and other metered arrival aircraft. This time is eitherthe VTA of the aircraft or the TCLT/ACLT of theprevious aircraft plus the AAI, whichever is later.PCG T−1
