How many feet of obstruction clearance is provided during a circling maneuver if the aircraft remains within the appropriate circling area?

During a circling maneuver, the obstruction clearance provided is specifically designed to ensure safety while an aircraft transitions from an instrument approach to visual flight and maneuvers to land. The standard vertical clearance from obstructions within the circling area is established to preserve a safe margin above potential hazards.

The correct choice indicates that there is a clearance of 300 feet provided during this maneuver. This amount of vertical clearance is in accordance with guidelines that account for various factors, including altitude considerations, aircraft performance, and the need for a buffer against unexpected changes in flight path or altitude.

Aircraft remain within the designated circling area for the maneuver, ensuring that the 300 feet of clearance is applicable and helps mitigate risks associated with obstacles. This clearance allows pilots to safely navigate in proximity to the airport while maintaining enough altitude above any terrain or structures that might be present in the area.
