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 indication
shown on a radar display resulting from a
primary radar return or a radar beacon reply.
TAS-
(See TERMINAL AUTOMATION SYSTEMS.)
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.
TCAS-
(See TRAFFIC ALERT AND COLLISION
AVOIDANCE SYSTEM.)
TCH-
(See THRESHOLD CROSSING HEIGHT.)
TCLT-
(See TENTATIVE CALCULATED LANDING
TIME.)
TDLS-
(See TERMINAL DATA LINK SYSTEM.)
Pilot/Controller Glossary 2/14/08
PCG T-2
TDZE-
(See TOUCHDOWN ZONE ELEVATION.)
TELEPHONE INFORMATION BRIEFING SERVICE-
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.
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, and on occasion
en route aircraft.
(See APPROACH CONTROL FACILITY.)
(See TOWER.)
TERMINAL AUTOMATION SYSTEMS (TAS)-
TAS is used to identify the numerous automated
tracking systems including ARTS IIE, ARTS IIIA,
ARTS IIIE, STARS, and MEARTS.
TERMINAL DATA LINK SYSTEM (TDLS)- A
system that provides Digital Automatic Terminal
Information Service (D-ATIS) both on a specified
radio frequency and also, for subscribers, in a text
message via data link to the cockpit or to a gate
printer. TDLS also provides Pre-departure Clearances
(PDC), at selected airports, to subscribers,
through a service provider, in text to the cockpit or to
a gate printer. In addition, TDLS will emulate the
Flight Data Input/Output (FDIO) information within
the control tower.
TERMINAL RADAR SERVICE AREA- 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.
TERMINAL VFR RADAR SERVICE- A national
program instituted to extend the terminal radar
services provided instrument flight rules (IFR)
aircraft to visual flight rules (VFR) aircraft. The
program is divided into four types service referred to
as basic radar service, terminal radar service area
