Alternate Entries and Precautionary Approaches
Familiarization
Procedures: Parallel Entry
Arrive at high key at 80% power, 200 KIAS and 5,000 ft AGL on a heading parallel to, and directly
overhead the landing point (Figure 28). At high key, lower the gear and 1/2 flaps, initiate a 25-35 degree
AOB turn to arrive at low key at 3,000 ft AGL. Continue the approach as discussed for the overhead
precautionary approach (perpendicular entry).

final) with the runway made,
go to full flaps/slats,
speed brakes as required
bank angle = 25 degrees
Final
330 ft AGL, 160 KIAS

Techniques
During an overhead precautionary approach, you can adjust your turn radius to compensate for deviations
from the optimum checkpoint altitudes. If low, you can retract the speed brakes and tighten your turn. If
high, you can fly a little wider pattern. In no case should you turn away from the runway to correct for
being too high.
