What is the visibility requirement in Class D airspace?

In Class D airspace, the visibility requirement is set at 3 statute miles. This regulation is designed to ensure that pilots have sufficient visual reference to navigate safely and avoid collisions with other aircraft and obstacles. The 3-mile visibility rule allows pilots to operate an aircraft while maintaining visual contact with their surroundings, which is crucial for maintaining situational awareness, especially in busy airspace where there may be other aircraft operating in proximity.

When pilots are flying in Class D airspace, which typically surrounds smaller airports with controlled operations, this visibility requirement supports safe takeoffs, landings, and general maneuvering. It allows for effective communication and coordination with air traffic control. The rule emphasizes the importance of pilots being able to see and avoid other traffic, as well as having a clear view of the runway and approach paths while operating in the vicinity of the controlled airspace.
