the gear down and flaps 20. When these conditions are encountered consider
retracting the landing gear for the circling portion of the approach after the descent
to MDA(H). The GPWS gear override switch may be used to prevent nuisance
warnings.
Missed Approach - Circling
If a missed approach is required at any time while circling, make a climbing turn
in the shortest direction toward the landing runway. This may result in a turn
greater than 180° to intercept the missed approach course. Maintain the missed
approach flap setting until close-in maneuvering is completed.

Different patterns may be required to become established on the prescribed missed
approach course. This depends on airplane position at the time the missed
approach is started. The following figure illustrates the maneuvering that may be
required. This ensures the airplane remains within the circling and missed
approach obstruction clearance areas.
In the event that a missed approach must be accomplished from below the
MDA(H), consideration should be given to selecting a flight path which assures
safe obstacle clearance until reaching an appropriate altitude on the specified
missed approach path.

Visual Approach - General
The recommended landing approach path is approximately 2 1/2° to 3°. Once the
final approach is established, the airplane configuration remains fixed and only
small adjustments to the glide path, approach speed, and trim are necessary. This
results in the same approach profile under all conditions.
Thrust
Engine thrust and elevators are the primary means to control attitude and rate of
descent. Adjust thrust slowly using small increments. Sudden large thrust changes
make airplane control more difficult and are indicative of an unstable approach.
No large changes should be necessary except when performing a go-around. Large
thrust changes are not required when extending landing gear or flaps on downwind
and base leg. A thrust increase may be required when stabilizing on speed on final
approach.
Downwind and Base Leg
Fly at an altitude of 1500 feet above the runway elevation and enter downwind
with flaps 5 at flaps 5 maneuvering speed. Maintain a track parallel to the landing
runway approximately 2 NM abeam.
Before turning base leg, extend the landing gear, select flaps 20, arm the
speedbrake, and slow to flaps 20 maneuvering speed or approach speed plus wind
correction if landing at flaps 20. If the approach pattern must be extended, delay
lowering gear and selecting flaps 20 until approaching the normal visual approach
profile. Turning base leg, adjust thrust as required while descending at
approximately 600-700 fpm.
Extend landing flaps before turning final. Allow the speed to decrease to the
proper final approach speed and trim the airplane. Complete the Landing
checklist. When established in the landing configuration, maneuvering to final
approach may be accomplished at final approach speed (VREF + wind
correction).
