Instrumenttilentämisen

Instrumenttilentämisen, often abbreviated as IFR, is a set of regulations, procedures, and skills that permit an aircraft pilot to fly in conditions where visual flight is not possible. This means flying without reference to the ground or external visual cues. IFR relies on the aircraft's instruments, such as the attitude indicator, altimeter, heading indicator, and navigation systems, to maintain control of the aircraft and navigate to the intended destination.

To fly under IFR, pilots must undergo specialized training and obtain an Instrument Rating in addition to their pilot's license. This training covers instrument interpretation, navigation techniques using various radio aids and GPS, understanding of airspace rules specific to IFR flight, and emergency procedures under instrument meteorological conditions (IMC). Air traffic control plays a crucial role in IFR, providing separation between aircraft and guiding them along approved routes.

IFR flight allows aviation to operate more reliably, especially in adverse weather such as fog, clouds, or low visibility. It is essential for commercial aviation and many other types of flying operations where timely and predictable travel is required. The principles of instrument flying are also foundational for military pilots and those involved in advanced flight training. Proficiency in instrument flight requires continuous practice and adherence to strict procedural standards to ensure safety.
