What is the minimum visibility requirement for a VFR departure below 10,000 feet?

The minimum visibility requirement for a VFR (Visual Flight Rules) departure below 10,000 feet is indeed 3 miles. This requirement is established to ensure that pilots can safely navigate the airspace and maintain visual separation from other aircraft and obstacles. The 3-mile visibility allows pilots to effectively see and avoid terrain, other aircraft, and any potential hazards in the vicinity during departure.

While other visibility requirements exist for different types of operations or altitudes, the specific 3-mile standard for departures under VFR below 10,000 feet helps to promote safe flying conditions, ensuring that pilots have sufficient visibility to make informed decisions and fly safely.
