Which regulations govern VFR flight in controlled airspace?

The regulations that govern VFR flight in controlled airspace are outlined in FAR Part 91. This part of the Federal Aviation Regulations provides the operational rules for all pilots and aircraft, including requirements for visual flight rules (VFR) operations.

Under FAR Part 91, pilots operating under VFR are required to comply with specific visibility and cloud clearance criteria, which are essential for maintaining safe separation from other aircraft and obstacles in controlled airspace. Additionally, Part 91 details the responsibilities of pilots, including the need for communication with air traffic control when operating in controlled airspace.

The other parts mentioned address different types of operations. For example, FAR Part 121 pertains to scheduled air carriers and requires different operational standards, while FAR Part 135 covers commuter and on-demand operations, outlining regulations specific to that sector. FAR Part 77 relates to the safe and proper use of navigable airspace but does not specifically address VFR operations in controlled airspace. Thus, FAR Part 91 is the key reference for VFR flight rules within controlled airspace.
