IFR Flight stands for Instrument Flight Rules, which is a set of regulations under which a pilot operates an aircraft in weather conditions that require reliance on instruments for navigation and control. This type of flight is essential when visibility is low due to clouds, fog, or rain, allowing pilots to safely navigate and land using instruments rather than visual references. In IFR Flight, pilots must be trained and certified to fly under these rules, which include specific procedures for communication with air traffic control. Aircraft must also be equipped with the necessary instruments and technology, such as GPS and altimeters, to ensure safe operation in challenging conditions.
