What must a site survey include regarding obstacles?

A site survey is a critical part of flight operations, particularly in preparing for safe takeoffs and landings. It must include the locations and heights of obstacles to ensure the safety and effectiveness of flight maneuvers. The identification of obstacles is vital as they directly influence the flight path and clearance required for aircraft operations. Knowing where these obstacles are located and how tall they are allows pilots to assess potential hazards and plan accordingly, thereby avoiding collisions and ensuring safe clearance during flight operations.

In many flight operations regulations and safety protocols, a thorough understanding of the physical environment, including obstacles, is emphasized. This information helps in creating flight paths, planning approaches, and determining safe operating altitudes that account for the terrain and structures in the vicinity of the flight area.
