Flow Management System (TFMS) to enable
airlines, controllers, and airports to share and
exchange real
−
time data. This improves surface
traffic management and enhances capabilities of
TFMS and TBFM. TFDM assists the Tower
personnel with surface Traffic Flow Management
(TFM) and Collaborative Decision Making (CDM)
and enables a fundamental change in the Towers from
a local airport
−
specific operation to a NAS
−
connect-
ed metering operation. The single platform
consolidates multiple Tower automation systems,
including: Departure Spacing Program (DSP),
Airport Resource Management Tool (ARMT),
Electronic Flight Strip Transfer System (EFSTS),
and Surface Movement Advisor (SMA). TFDM data,
integrated with other FAA systems such as TBFM
and TFMS, allows airlines, controllers, and airports
to manage the flow of aircraft more efficiently
through all phases of flight from departure to arrival
gate.
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 SEQUENCING AND SPACING
(TSAS)
−
Extends scheduling and metering capabili-
ties into the terminal area and provides metering
automation tools to terminal controllers and terminal
traffic management personnel. Those controllers and
traffic management personnel become active partici-
pants in time
−
based metering operations as they work
to deliver aircraft accurately to Constraint Satisfac-
tion Points within terminal airspace to include the
runway in accordance with scheduled times at those
points. Terminal controllers are better able to utilize
efficient flight paths, such as Standard Instrument
Approach Procedures (SIAPs) that require a
Navigational Specification (NavSpec) of RNP
APCH with Radius
−
to
−
Fix (RF) legs, or Advanced
RNP (A
−
RNP), through tools that support the
merging of mixed
−
equipage traffic flows. For
example, merging aircraft flying RNP APCH AR
with RF, A
−
RNP, and non
−
RNP approach proce-
dures. Additional fields in the flight plan will identify
those flights capable of flying the RNP APCH with
RF or A
−
RNP procedures, and those flights will be
scheduled for those types of procedures when
available. TSAS will schedule these and the
non
−
RNP aircraft to a common merge point.
Terminal traffic management personnel have im-
proved situation awareness using displays that allow
for the monitoring of terminal metering operations,
similar to the displays used today by center traffic
management personnel to monitor en route metering
operations.
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
(TRSA) service, Class B service and Class C service.
The type of service provided at a particular location
is contained in the Chart Supplement U.S.
a.
Basic Radar Service
−
These services are
provided for VFR aircraft by all commissioned
terminal radar facilities. Basic radar service includes
safety alerts, traffic advisories, limited radar
vectoring when requested by the pilot, and
sequencing at locations where procedures have been
established for this purpose and/or when covered by
a letter of agreement. The purpose of this service is to
adjust the flow of arriving IFR and VFR aircraft into
the traffic pattern in a safe and orderly manner and to
provide traffic advisories to departing VFR aircraft.
b.
TRSA Service
−
This service provides, in
addition to basic radar service, sequencing of all IFR
and participating VFR aircraft to the primary airport
and separation between all participating VFR
aircraft. The purpose of this service is to provide
separation between all participating VFR aircraft and
all IFR aircraft operating within the area defined as a
TRSA.
c.
Class C Service
−
This service provides, in
addition to basic radar service, approved separation
between IFR and VFR aircraft, and sequencing of
VFR aircraft, and sequencing of VFR arrivals to the
primary airport.
d.
Class B Service
−
This service provides, in
addition to basic radar service, approved separation
of aircraft based on IFR, VFR, and/or weight, and
sequencing of VFR arrivals to the primary airport(s).
