What does the acronym IFR stand for?

The acronym IFR stands for Instrument Flight Rules. This term is crucial in aviation, as it dictates the regulations under which aircraft operate in controlled airspace and during instrument meteorological conditions. Under IFR, pilots navigate primarily by using instruments and rely on air traffic control for guidance, especially when visibility is poor or when flying in cloud cover.

By adhering to IFR, pilots ensure they maintain proper separation from other aircraft and avoid hazards, as the rules are designed to provide a structured framework for safe flying in more challenging conditions. This is in contrast to VFR, or Visual Flight Rules, where pilots navigate and control the aircraft based on visual references outside the cockpit. Understanding IFR is essential for pilots, especially those flying in diverse weather patterns or within busy air traffic environments.
