Final answer:
VFR flight is permitted under specific weather conditions set by the FAA, which include minimum visibility of 3 miles and specific cloud clearances. These VFR weather conditions are part of aviation flight categories, such as Visual Meteorological Conditions (VMC).
Step-by-step explanation:
The aviation flight category in which visual flight rules (VFR) flight is permitted involves specific weather conditions that pilots must adhere to for the safety and regulation of air traffic. For VFR flight to be permitted, the Federal Aviation Administration (FAA) has set minimum visibility and cloud clearance requirements that must be met.
These requirements differ based on the airspace class but generally include a minimum visibility of 3 miles and cloud clearances of at least 500 feet below, 1,000 feet above, and 2,000 feet horizontally from the cloud. Furthermore, the flight must be conducted in what are known as VFR weather conditions, which are typically represented in weather reports and forecasts by various aviation flight categories such as Visual Meteorological Conditions (VMC).
