Authority of India has replaced the existing Instrument Landing System (ILS)
for runway 07 at Chennai International airport at a cost of Rs. 5.0 Crores. ILS
provides the necessary guidance to pilots as they approach for landing at the
runway. The new ILS will facilitate smooth landing of the aircrafts at Chennai
Airport even during rain, low clouds, smog etc. and provide an improved
guidance to the Aircrafts, says an official release.
new system uses a highly directional antenna system - “Wide Aperture Log
Periodic Antenna Array [LPDA]” system. This antenna system has addressed the
coverage restrictions of the old ILS, and will provide guidance to the aircraft
to a much lower height and improved precision. This is turn will enhance the
safety of the aircraft during landing.
state of the art equipment is manufactured by M/s Indra Navia AS, Norway. The
complete installation, alignment, testing, flight inspection and commissioning
of the new Instrument Landing System has been done in-house by AAI’s CNS
