What does IFR stand for in aviation?

In aviation, IFR stands for Instrument Flight Rules. This term is crucial for pilots operating under conditions where visual navigation is not feasible, typically due to poor weather or other obstacles. Under IFR, pilots rely on instruments and navigational aids to control the aircraft and maintain orientation. This framework ensures safety and standardizes operations in controlled airspace, allowing pilots to fly in clouds or reduced visibility while navigating effectively.

The significance of IFR extends to compliance with regulations set by aviation authorities, providing a structured approach to flying that enhances coordination and communication among pilots and air traffic control. Understanding IFR is key for any commercial pilot, as it encompasses not only the operational procedures but also the necessary certifications and training required to operate an aircraft in such conditions safely.
