Which equipment is not required for Day VFR operations under 91.205?

In the context of Day VFR (Visual Flight Rules) operations under FAR 91.205, certain equipment is mandated to ensure the safety and functionality of the aircraft. Among the equipment listed, the landing light is not required for Day VFR operations.

The regulations specify that while operational instruments such as an oil pressure gauge, altimeter, and temperature gauge are necessary to monitor engine performance and flight conditions, the landing light is only required for aircraft operating for hire or during certain night operations. Therefore, for daytime operations, the landing light does not meet the criteria for mandatory equipment, allowing pilots to conduct VFR flights without it.

This distinction is important for pilots to understand what equipment is essential for compliance with regulations governing safe flight operations and to ensure they are adequately prepared for their flights.
