Instrument Landing System (ILS)
Most navigation systems approved for Enroute and terminal operations under IFR, such as VOR, NDB, and GPS, may also be approved to conduct instrument approach procedures. The most common system in use in the United States is the ILS. An ILS (instrument landing system) operates as a ground-based instrument approach system, using a combination of radio signals, during IMC conditions, this system will guide airplanes to land during low ceilings or reduced visibility due to fog, rain, or blowing snow.
Flying the ILS
After knowing the basic ILS principles and how the system works, the pilot must demonstrate the procedures on how to fly a precision instrument approach “ILS” during his/her checkride. This course will include a complete video on how to fly an ILS approach.
