No person may take off or land an aircraft under basic VFR at an airport that lies within Class D airspace unless the?

Taking off or landing an aircraft under basic VFR (Visual Flight Rules) within Class D airspace requires that specific visibility conditions are met to ensure safe operations and pilot situational awareness. The correct requirement is that ground visibility at the airport must be at least 3 miles. This stipulation is important because it assures that the pilot has adequate horizontal visibility for both departure and arrival operations.

Ground visibility is a critical factor since it indicates the distance at which objects can be seen on the ground. Under VFR conditions, pilots need to maintain visual reference not only to the runway during landing but also to avoid obstacles and ensure safe navigation to and from the runway. The 3-mile visibility requirement is established to ensure that pilots can see enough of their surroundings to operate the aircraft safely without relying solely on instruments.

For Class D airspace, which typically encompasses controlled airports surrounded by a 4 nautical mile radius up to 2,500 feet above the airport elevation, these additional visibility standards are vital for maintaining safety among multiple aircraft operating in a defined area. The clarity provided by 3 miles of ground visibility helps mitigate risks related to congestion and potential conflicts with other air traffic.

In contrast, other options refer to lower visibility requirements, which would not sufficiently ensure safety
