TERMINAL ARRIVAL AREA (TAA)
−
The
TAA is controlled airspace established in conjunction
with the Standard or Modified T and I RNAV
approach configurations. In the standard TAA, there
are three areas: straight-in, left base, and right base.
The arc boundaries of the three areas of the TAA are
published portions of the approach and allow aircraft
to transition from the en route structure direct to the
nearest IAF. TAAs will also eliminate or reduce
feeder routes, departure extensions, and procedure
turns or course reversal.
1.
STRAIGHT-IN AREA
−
A 30 NM arc
centered on the IF bounded by a straight line
extending through the IF perpendicular to the
intermediate course.
2.
LEFT BASE AREA
−
A 30 NM arc centered
on the right corner IAF. The area shares a boundary
with the straight-in area except that it extends out for
30 NM from the IAF and is bounded on the other side
by a line extending from the IF through the FAF to the
arc.
3.
RIGHT BASE AREA
−
A 30 NM arc
centered on the left corner IAF. The area shares a
boundary with the straight-in area except that it
extends out for 30 NM from the IAF and is bounded
on the other side by a line extending from the IF
through the FAF to the arc.

RUNWAY MONITORING (PRM) APPROACH–
A GPS approach, which requires vertical guidance,
used in lieu of another type of PRM approach to
conduct approaches to parallel runways whose
extended centerlines are separated by less than 4,300
feet and at least 3,000 feet, where simultaneous close
parallel approaches are permitted. Also used in lieu
of an ILS PRM and/or LDA PRM approach to
conduct Simultaneous Offset Instrument Approach
(SOIA) operations.
ARMY AVIATION FLIGHT INFORMATION
BULLETIN
−
A bulletin that provides air operation
data covering Army, National Guard, and Army
Reserve aviation activities.
ARO
−
(See AIRPORT RESERVATION OFFICE.)
ARRESTING SYSTEM
−
A safety device consisting
of two major components, namely, engaging or
catching devices and energy absorption devices for
the purpose of arresting both tailhook and/or
nontailhook-equipped aircraft. It is used to prevent
aircraft from overrunning runways when the aircraft
cannot be stopped after landing or during aborted
takeoff. Arresting systems have various names; e.g.,
arresting gear, hook device, wire barrier cable.
(See ABORT.)
(Refer to AIM.)
ARRIVAL CENTER
−
The ARTCC having jurisdic-
tion for the impacted airport.
ARRIVAL DELAY
−
A parameter which specifies a
period of time in which no aircraft will be metered for
arrival at the specified airport.
ARRIVAL/DEPARTURE WINDOW (ADW)
−
A
depiction presented on an air traffic control display,
used by the controller to prevent possible conflicts
between arrivals to, and departures from, a runway.
The ADW identifies that point on the final approach
course by which a departing aircraft must have begun
takeoff
.
ARRIVAL SECTOR (En Route)
−
An operational
control sector containing one or more meter fixes on
or near the TRACON boundary.
ARRIVAL TIME
−
The time an aircraft touches down
on arrival.
