Arrival Procedures

until crossing over the PT fix or abeam and
proceeding outbound. Some procedures contain a
note in the chart profile view that says “Maintain
(altitude) or above until established outbound for
procedure turn” (See FIG 5

−4−16). Newer proced-

ures will simply depict an “at or above” altitude at the
PT fix without a chart note (See FIG 5

−4−17). Both

are there to ensure required obstacle clearance is

provided in the procedure turn entry zone (See
FIG 5

−4−18). Absence of a chart note or specified

minimum altitude adjacent to the PT fix is an
indication that descent to the procedure turn altitude
can commence immediately upon crossing over the
PT fix, regardless of the direction of flight. This is
because the minimum altitudes in the PT entry zone
and the PT maneuvering zone are the same.
