Which regulation outlines the required instruments and equipment for VFR day and night flight?

The regulation that outlines the required instruments and equipment for VFR (Visual Flight Rules) day and night flight is indeed found in 14 CFR 91.205. This section specifically details the minimum basic equipment and instruments that a pilot must have available for VFR operations during both day and night, including critical items such as a compass, altimeter, and other necessary gauges that ensure the safety and legality of the flight.

For day operations, some key requirements include a valid airspeed indicator, altimeter, and fuel gauge, while additional instruments are mandated for night operations, like anti-collision lights and a dedicated means for visual navigation. This structure ensures pilots have the necessary tools to operate the aircraft safely under varied visual conditions.

The other regulations mentioned do not cover the VFR equipment requirements directly. For example, 14 CFR 91.213 pertains to operations with inoperative instruments and equipment, while 14 CFR 91.9(a) relates to the responsibility and authority of the pilot in command regarding aircraft operation. Lastly, 14 CFR 91.91(c) discusses special flight rules in specific airspace areas. Therefore, these regulations serve different purposes and do not specifically address the VFR day and night equipment requirements as effectively as
