keep PART 77—SAFE, EFFICIENT USE, AND PRESERVATION OF THE NAVIGABLE AIRSPACE
Establishes FAA notice requirements and obstruction standards for construction/alteration near airports, including height limits, imaginary surfaces, and aeronautical studies to ensure aviation safety.
Aviation safety requires standardized obstruction standards and aeronautical studies to prevent collisions and maintain navigable airspace. Without these regulations, uncoordinated construction could create hazards to aircraft, especially near airports where precise height and distance requirements are critical for safe approaches and departures.
