Alternate Entries and Precautionary Approaches
Familiarization
OVERHEAD PRECAUTIONARY APPROACH
Procedures: Perpendicular Entry
Arrive at the high key over the approximate landing area at 80% power, 200 KIAS and 5,000 ft AGL on a
heading 90 degrees to the landing runway and approximately 4,000 ft down the runway (Figure 27). At
high key, lower gear and 1/2 flaps. Approximately three seconds after crossing the runway (high key),
initiate a 25-35 degree AOB turn at 4,700 ft AGL and extend the speed brakes while maintaining 175 KIAS.
The low key is at 3,000 ft AGL, 175 KIAS, approximately 3300-fpm rate of descent at 1.5 nm abeam in a
35-degree AOB turn.

Figure 27: OVERHEAD PRECAUTIONARY APPROACH (PERPENDICULAR ENTRY)
Adjust AOB and speed brakes to arrive at the 90-degree position at 1,500 ft AGL and 175 KIAS. At this
point begin to increase pitch attitude while decelerating to 165 KIAS. At the 45-degree position with the
appropriate altitude and airspeed to assure runway landing, lower full flaps and retract the speed brakes.
Intercept the extended runway centerline at 330 ft AGL and 160 KIAS. Continue the approach as
discussed for the straight in precautionary approach.
