Navigation and Observation Systems
ILS 2700. Instrument Landing System

PURPOSE:

The ILS 2700 ground equipment is intended for emitting amplitude-modulated RF signals in the specified zone. The signals contain data for receiving on board the aircraft equipped with the relevant devices. The ground equipment provides finding the aircraft position with reference to the runway during approach and landing phases. The ILS 2700 meets the requirements of ICAO Categories I, II, and III.
