What is the net takeoff flight path obstacle clearance requirement?

• A. 35 ft vertically or 200 ft horizontally within the airport boundaries and 300 ft beyond the airport boundaries.
• B. 50 ft vertically or 100 ft horizontally within boundaries and 200 ft beyond.
• C. 25 ft vertically or 300 ft horizontally within boundaries and 100 ft beyond.
• D. There is no net takeoff flight path requirement.

Answer: (A)

Net takeoff flight path obstacle clearance creates a protection envelope around the planned climb to ensure the aircraft can start its departure without encountering obstacles. Within the airport boundaries, any obstacle on or near the takeoff path must be clear by either having the obstacle no higher than 35 feet above the path or being kept at least 200 feet away horizontally from the path. If the obstacle lies beyond the airport boundaries, the required horizontal clearance increases to 300 feet. This combination of vertical and horizontal buffers helps guarantee a safe initial climb both inside and just outside the airfield. The other options don’t reflect these specific clearance figures and the reality that a net takeoff obstacle clearance requirement does exist.
