What is the lowest pattern altitude listed for KCBM?

The lowest pattern altitude listed for KCBM, which is the Columbus Airport, is 700 feet MSL (Mean Sea Level). This altitude is typically determined based on safety regulations, traffic patterns, and operational practices for airports.

In standard aviation practice, pattern altitudes for general aviation airports are often set at around 700-1000 feet MSL. The 700 feet MSL allows for effective traffic separation while still providing enough altitude for maneuvering and, if necessary, a safe emergency landing.

Choosing 700 feet MSL as the lowest pattern altitude ensures that aircraft can maintain a safe distance from the ground and obstacles while also being high enough for effective communication with air traffic control and other aircraft in the vicinity. This altitude aligns with the established FAA guidelines for smaller, non-towered airports, where the goal is to maintain safety in the airspace around an airport.
