3. INTERFACE BETWEEN STRAIGHT INITIAL APPROACH AREA
AND REVERSAL PROCEDURE AREAS
The secondary area width of a reversal procedure is:
a) 1.9 km (1.0 NM) if it is based on a VOR; and
b) 2.3 km (1.25 NM) if it is based on an NDB.
The corresponding areas are related as shown in Figure I-4-3-App B-9.
Note.— In Figure I-4-3-App B-9 the VOR facility marks the turning point in the initial approach segment. The
intermediate approach segment starts only after completion of the reversal procedure turn.
