The Instrument Landing System (ILS)

ILS facilities are a highly accurate and dependable means of navigating to the runway in IFR conditions. When using the ILS, the pilot determines aircraft position primarily by reference to instruments.

The ILS stations are installed at both international airports, which support the landing aircraft with instrument guidance under adverse weather conditions. ILS is used to provide the pilot with precision information of the aircraft direction so as he lands the aircraft, if it is possible, to touch the ground in the specific point. This point should be the centerline of the runway and be at the beginning of the runway. In addition, aircraft is landed at an angle of 3 degrees. So, the two of the landing guidance (i.e. runway centerline and 30 angle landing path) are provided by Localiser and Guide path respectively.

Communication

This system consists of air to ground radios used by the air traffic controllers to communicate with aircrafts. These radios are located at multiple sites across the island and in Grand Cayman. The air traffic controllers are at two International Airports, Tinson Pen and the Kingston Air Traffic Centre.
