What is the maximum elevation figure for safe obstruction clearance on a flight from Gnoss Airport to Rio Vista Airport?

The maximum elevation figure (MEF) represents the highest elevation within a given area, including terrain and any man-made structures, providing a buffer for safe navigation and obstacle clearance. When calculating this figure for a flight route from Gnoss Airport to Rio Vista Airport, considerations such as the surrounding terrain and potential obstructions must be assessed.

In this case, 3,200 feet MSL would provide an adequate margin above the highest ground level and any obstacles in that area, ensuring that a pilot can maintain safe clearance throughout the flight. This elevation accounts for not only the highest terrain but also other factors that could pose a risk, such as towers and buildings, within the designated airspace along the route.

Choosing a higher elevation than necessary can help prevent collision with these obstacles, especially in areas with variable terrain. Thus, 3,200 feet MSL is justified as a prudent choice that balances safety with efficiency.
