What is the visibility requirement for flight in Class E airspace below 10,000 feet?

In Class E airspace, which typically exists in controlled airspace beneath 10,000 feet, the visibility requirement for flight is set at 3 statute miles. This standard is part of the regulations established by the Federal Aviation Administration (FAA) and is designed to ensure pilots have sufficient visibility to operate their aircraft safely.

Meeting this visibility standard is crucial for maintaining situational awareness while flying, particularly in relation to other aircraft and the terrain below. It accommodates various flight operations, including Visual Flight Rules (VFR), allowing pilots to navigate and make decisions effectively based on visual references.

The other visibility figures would not meet the regulatory requirements as they either exceed or fall short of what is mandated for safe visibility in Class E airspace. The 3 statute miles requirement strikes a balance that is considered safe for pilots operating under VFR in this type of airspace.
