What regulation governs takeoff and landing criteria in IFR for pilots?

The regulation that governs takeoff and landing criteria in IFR (Instrument Flight Rules) for pilots is FAR 91.175. This regulation specifically outlines the requirements for instrument approach procedures, including the criteria for safe takeoff and landing under IFR conditions. The rule ensures that pilots understand the minimum visibility and distance requirements necessary to execute these maneuvers safely, as well as the necessary procedures to follow during different phases of flight in instrument conditions. This is crucial for maintaining safety and operational integrity when flying in poor visibility or other challenging conditions.
