Which Part addresses obstructions around airports?

• A. Part 77
• B. Part 107
• C. Part 150
• D. Part 1542

Answer: (A)

Obstructions around airports are regulated to protect navigable airspace. Part 77 governs how obstructions near airports are evaluated and controlled. It establishes rules for what counts as an obstruction, requires notice to the FAA for proposed structures or vegetation, and uses imaginary surfaces around airports to determine if something could interfere with aircraft during approach, takeoff, or departures. This focus on identifying and addressing potential hazards to flight paths is why it’s the right choice for questions about obstructions around airports.

The other parts cover different topics: Part 107 deals with small unmanned aircraft operations, Part 150 addresses noise compatibility planning near airports, and Part 1542 covers airport traffic control tower operations.
