· The circling approach should be flown with landing gear down, flaps 15, and at flaps 15 maneuvering speed. Use the weather minima associated with the anticipated circling speed. · Maintain MDA (ALT HOLD mode) and use HDG SEL for tracking. · Prior to turning Base leg, select landing flaps and begin decelerating to the approach speed. This assures minimum turning radius to the runway. Complete the landing checklist. · Do not descend below MDA until intercepting the visual profile. Note: To avoid overshooting final approach course, adjust the turn to final to initially aim at the inside edge of the runway threshold. CIRCLING APPROACH - ONE ENGINE INOPERATIVE · If a circling approach is anticipated, maintain gear up, flaps 10, and flaps 10 maneuvering speed from the final approach fix to just prior to turning base. As an option, or if flaps 10 selection is not available, use flaps 5, and flaps 5 maneuvering speed as the approach flaps setting for the circling approach. · Prior to turning base, select gear down and flaps 15 and begin reducing speed to flaps 15 maneuvering speed. Intercept the landing profile and reduce speed to VREF 15 plus the wind correction (minimum VREF 15 + 5 knots). · Do not descend below MDA until intercepting the visual profile. CIRCLING MISSED APPROACH · If a missed approach is required at any time while circling, turn toward the approach runway to reach the missed approach heading even if the turn is more than 180 degrees and not in the shortest direction. · 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. · Figure below illustrates the maneuvering that may be required. This will ensure the airplane will remain within the circling and missed approach obstruction clearance areas.

At a positive rate of climb call "gear up," adjust the pitch attitude to maintain "cursor" speed. At a safe altitude and appropriate speed, retract flaps on the speed schedule. Accomplish the missed approach procedure as illustrated on the approach chart. · If a turning missed approach is required, accomplish the missed approach procedure through gear up before initiating the turn. Limit bank angle to 15 degrees until accelerating to VREF 15 plus 15 knots, or to the minimum maneuvering speed displayed on MASI/Speed Tape airplanes. Delay further flap retraction until initial maneuvering is complete and a safe altitude and appropriate speed are attained. · The minimum altitude for flap retraction during takeoff is not normally applicable to a missed approach procedure; however, obstacles in the missed approach flight path must be taken into consideration.
