TAKEOFF AREA-
(See LANDING AREA.)
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.
TARGET- The indication shown on an analog display resulting from a primary radar return or a radar beacon reply.
(See ASSOCIATED.)
(See DIGITAL TARGET.)
(See DIGITIZED RADAR TARGET.)
(See PRIMARY RADAR TARGET.)
(See RADAR.)
(See SECONDARY RADAR TARGET.)
(See TARGET SYMBOL.)
(See ICAO term TARGET.)
(See UNASSOCIATED.)
TARGET [ICAO]- In radar:
a..
Generally, any discrete object which reflects or retransmits energy back to the radar equipment.
b.
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:
a..
Between the edges of two primary targets or the edges of the ASR‐9 primary target symbol.
b..
Between the end of the beacon control slash and the edge of a primary target.
c..Between the ends of two beacon control slashes.
Note 1: MANDATORY TRAFFIC ADVISORIES AND SAFETY ALERTS SHALL BE ISSUED WHEN THIS PROCEDURE IS USED.
Note 2: This procedure shall not be provided utilizing mosaic radar systems.
TARGET SYMBOL- A computer‐generated indica-tion shown on a radar display resulting from a primary radar return or a radar beacon reply.

TAWS-
(See TERRAIN AWARENESS WARNING
SYSTEM.)
TAXI- The movement of an airplane under its own power on the surface of an airport (14 CFR Section 135.100 [Note]). Also, it describes the surface movement 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 illustrate the desired flow of ground traffic for the different runways or airport areas available for use.

AVOIDANCE SYSTEM.)
TCH-
(See THRESHOLD CROSSING HEIGHT.)
TCLT-
(See TENTATIVE CALCULATED LANDING
TIME.)
TDLS-(See TERMINAL DATA LINK SYSTEM.)
TDZE-
(See TOUCHDOWN ZONE ELEVATION.)
TELEPHONE INFORMATION BRIEFING SER-VICE- A continuous telephone recording of meteorological and/or aeronautical information.
(Refer to AIM.)
TENTATIVE CALCULATED LANDING TIME- A projected time calculated for adapted vertex for each arrival aircraft based upon runway configuration, airport acceptance rate, airport arrival delay period, and other metered arrival aircraft. This time is either the VTA of the aircraft or the TCLT/ACLT of the previous aircraft plus the AAI, whichever is later. This time will be updated in response to an aircraft's progress and its current relationship to other arrivals.
