Arrival Procedures
FIG 5
−4−8
Sectored TAA Areas
(c)
Depiction of the TAA on U.S. Govern-
ment charts will be through the use of icons located
in the plan view outside the depiction of the actual
approach procedure. (See FIG 5−4−9). Use of icons
is necessary to avoid obscuring any portion of the “T”
procedure (altitudes, courses, minimum altitudes,
etc.). The icon for each TAA area will be located and
oriented on the plan view with respect to the direction
of arrival to the approach procedure, and will show all
TAA minimum altitudes and sector/radius subdivi-
sions for that area. The IAF for each area of the TAA
is included on the icon where it appears on the ap-
proach, to help the pilot orient the icon to the
approach procedure. The IAF name and the distance
of the TAA area boundary from the IAF are included
on the outside arc of the TAA area icon. Examples
here are shown with the TAA around the approach to
aid pilots in visualizing how the TAA corresponds to
the approach and should not be confused with the
actual approach chart depiction.
(d)
Each waypoint on the “T”, except the
missed approach waypoint, is assigned a pronounce-
able 5−character name used in air traffic control
communications, and which is found in the RNAV
databases for the procedure. The missed approach
waypoint is assigned a pronounceable name when it
is not located at the runway threshold.
6.
Once cleared to fly the TAA, pilots are
expected to obey minimum altitudes depicted within
the TAA icons, unless instructed otherwise by air
traffic control. In FIG 5−4−8, pilots within the left or
right−base areas are expected to maintain a minimum
altitude of 6,000 feet until within 17 NM of the
associated IAF. After crossing the 17 NM arc, descent
is authorized to the lower charted altitudes. Pilots
approaching from the northwest are expected to
maintain a minimum altitude of 6,000 feet, and when
within 22 NM of the IF (IAF), descend to a minimum
altitude of 2,000 feet MSL until reaching the IF
(IAF).
