This is the final video in our Obstacle Limitation Surfaces series, which includes Airport Airspace Protection, https://www.youtube.com/watch?v=rQ8AbAgok-0 and Airport Airspace Evaluation Process: Best Practices, https://www.youtube.com/watch?v=YMWAuWmolxI.
This is the third video in the airspace protection series and presents an airspace case study
illustrating the safety impacts to both airports and local communities when building a project
without FAA notification. The FAA protects airspace off the ends of runways and around
airports for the safe arrival and departure of aircraft. Structures in development near
an airport can adversely affect the ability of aircraft to use their runway safely.
What happens if a tall structure was built that interfered with the airspace established for
safe flight routes and the FAA was not notified in advance so they could re-evaluate the safety
of the airspace considering the new structure? Here's an example of what could happen. A pilot
operating an aircraft fully loaded with passengers and cargo takes off during inclement weather and
has difficulty climbing over a structure near the runway end. The pilot reports the incident to the
and also reports that the structure was not listed on the flight obstruction data provided to them.
After the pilot's report, two events happen immediately. First, the FAA assesses the
structure and its impact on the airport's operations. They determine that the structure
was built without FAA notification, interferes with flight departures, causes substantial impacts
to the airport, and is considered a safety hazard. Second, the airport operator and the FAA take the
decrease the runway length available for takeoff, issue a notice to pilots,
submit the object for entry on the flight obstruction data provided to pilots,
and investigate less impactful alternatives. Decreasing the runway available for takeoff
negatively impacts the airport and departure operations by reducing the maximum allowable
takeoff weight, decreasing the destination range, and reducing the airport capacity,
most likely causing delays. Following the immediate mitigations, the FAA, local community,
and building owner collaborated to lower the structure at the builder's expense.
Now the building is lower and the airport reclaims the full runway length,
thus eliminating the impacts on flight range and capacity. Had there been coordination with the
FAA prior to construction, the aircraft near accident and the builder's subsequent expense
of lowering the building would have been avoided. The FAA's initial evaluation would have presumed
the building to be a hazard, and they would have assisted with the appropriate building height
determination. Though the situation ended safely and collaboratively, there were multiple potential
consequences like safety risks, operational disruptions, and financial implications.
Safety risks. Hazards during critical takeoff and landing flight phases near an airport,
especially at night or under foggy, rainy, or snowy conditions. Unknown obstacles near an airport
create an elevated collision risk potentially resulting in loss of life, property damage,
loss of the aircraft, airport shutdown, and lawsuits. Financial implications. Repairing
damage from accidents could be costly to the airport, air carriers, the building owner,
and local businesses. Burdensome fines and especially illegal settlements.
Repercussions may result from not providing obstacle notification to the FAA, including
monetary fines imposed on individuals, organizations, or operators. Civil lawsuits or legal
action brought against the violators. Increased insurance premiums or denial of coverage.
Restrictions on flight operations either through limiting the distance of flight routes,
flight path changes, or the size of aircraft able to use the runway, cause delays, and increase
fuel consumption. Protecting airport airspace is crucial to maintaining current and future airport
capacity, safety, and efficiency while supporting economic development near airports. Through its
programs, the FAA helps ensure a safe, efficient, and environmentally responsible national airport
system that meets the needs of the traveling public, the nation, and the world. These reference

contact your local FAA office for any questions related to airspace protection and proposed
development near airports. The FAA appreciates your interest. Safe flying!
