What is the floor of Class E airspace over University Airport (0O5)?

Class E airspace is a controlled airspace that can extend from the surface or from a specified floor to a ceiling of 18,000 feet MSL (Mean Sea Level). Over areas like the University Airport (0O5), which is likely in a rural or less populated region, the bottom of Class E airspace is usually established at 700 feet above ground level (AGL).

This height serves multiple purposes, including providing controlled airspace for aircraft operations that need to maintain separation from other air traffic, especially in the vicinity of airports. Therefore, identifying the floor of Class E airspace as 700 feet AGL indicates that air traffic operations in that area will generally be influenced by the rules and regulations governing this airspace segment, which starts above ground level to ensure safer air navigation and traffic management.

In scenarios where the floor of Class E is set at the surface, it would apply to specific airports or airfields where increased traffic is anticipated, such as in Class E airspace that surrounds busy airports. Thus, claiming the floor is at the surface would not typically apply to a university airport setting, which is more often categorized with a higher threshold for airspace. Similarly, the options for 1,200 feet or 1
