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.
