TAKE-OFF DISTANCE AVAILABLE (ICAO) - The length of the take-off run available plus the length of the clearway if provided.
TAKE-OFF RUN AVAILABLE (ICAO) - The length of runway declared available and suitable for the ground run of an aeroplane take-off.
TAKE-OFF SAFETY SPEED - A referenced airspeed obtained after liftoff at which the required one-engine-inoperative climb performance can be achieved. (Refer to Federal Air Regulations, Part 91)
TARGET (P/CG) - The indication shown on a radar display resulting from a primary radar return or a radar beacon reply. (See Target Symbol, Radar)
TARGET (ICAO) - In radar:
(1) Generally, any discrete object which reflects or retransmits energy back to the radar equipment;
(2) Specifically, an object of radar search or surveillance.
TARGET RESOLUTION - A process to ensure that correlated radar targets do not touch. Target resolution shall be applied as follows:
(1)
Between the edges of two primary targets or the edges of the ASR-9 primary target symbol.

(2)
Between the end of the beacon control slash and the edge of a primary target.

(3)
Between the ends of two beacon control slashes. MANDATORY TRAFFIC ADVISORIES AND SAFETY ALERTS SHALL BE ISSUED WHEN THIS PROCEDURE IS USED.


Note: This procedure shall not be provided utilizing mosaic radar systems.
TARGET SYMBOL - A computer generated indication shown on a radar display resulting from a primary radar return or a radar beacon reply.
TAXI - The movement of an airplane under its own power on the surface of an airport (Federal Air Regulations Part 135.100-Note). Also, it describes the surface movement of helicopters equipped with wheels. (See Air Taxi, Hover Taxi) (Refer to 7110.65-972)
TAXI PATTERNS - Patterns established to illustrate the desired flow of ground traffic for the different runways or airport areas available for use.
TELEPHONE INFORMATION BRIEFING SERVICE/TIBS - A continuous telephone recording of Meteorological and / or aeronautical information. (refer to Airman's Information Manual)
TEMPO - Used in Meteorological messages (See Landing Forecast Trend type).
TEMPORARY RESERVED AIRSPACE/TRA (NGA) - An airspace of defined dimensions within which certain military flying activities dangerous to the flight of civil aircraft may exist at specified times. These published areas may for operational and/or safety reasons be extended laterally as well as vertically by NOTAM.
TEMPORARY SEGREGATED AIRSPACE/TSAs (NGA) - TSAs are airspace of defined dimensions, within which activities require the reservation of airspace for the exclusive use of specific users during a determined period of time. TSAs permit activities requiring temporary reservation to be allocated on the day before operations. This allows the Airspace Management Cell (AMC) to make available, if required, Conditional Routes (CDRs) outside the planned hours of associated TSAs. All airspace reservations (TSAs) and restrictions (Danger/Restricted Areas, MTAs, AARAs etc.) that are managed and allocated the day before operations by the AMC, are identified as "AMC Manageable Areas" in the relevant AIP. Any remaining Danger and Restricted areas that are not suitable for AMC management remain unaltered.
TEND - Used in Meteorological messages (See Landing Forecast Trend type).
TERMINAL AREA - A general term used to describe airspace in which approach control service or airport traffic control service is provided.
TERMINAL AREA FACILITY -A facility providing Air Traffic Control service for arriving and departing IFR, VFR, special VFR, special IFR aircraft and on occasion, enroute aircraft. (See Approach Control, Tower)
TERMINAL CONTROL AREA - (See Controlled Airspace)
TERMINAL CONTROL AREA (JCS, NATO, ICAO) - A control area normally established at the confluence of Air Traffic Service routes in the vicinity of one or more major airfields.
TERMINAL RADAR SERVICE AREA/TRSA - Airspace surrounding designated airports wherein ATC provides radar vectoring, sequencing, and separation on a full-time basis for all IFR and participating VFR aircraft. The AIM contains an explanation of TRSA. TRSAs are depicted on VFR aeronautical charts. Pilot participation is urged but is not mandatory.
