What is the MSA primarily centered around?

The MSA, or Minimum Safe Altitude, is primarily centered around the navigational station. This altitude is designed to provide a safe buffer for aircraft operating in the vicinity of a navigational aid, ensuring that they remain clear of obstacles and terrain while navigating. The MSA is calculated based on the elevation of the navigational station and the surrounding terrain, making it crucial for pilots to understand and comply with these safe altitudes when flying in the vicinity of these points.

While flight path adherence, weather patterns, and runway orientation are important considerations in aviation, they don't directly define the core focus of MSA. MSA specifically serves to ensure safety for aircraft relative to navigational aids, allowing pilots to confidently navigate without the risk of collision with obstacles in the area.
