The Instrument Landing System (ILS) at the Gannavaram Airport near here will become fully operational by February-end. A team of technical experts from the Airports Authority of India on Thursday began fine-tuning the operation of the system with a fully-equipped AAI aircraft (VT-EPU) specially to test various parameters of the CAT-1 ILS at the airport.

The process will continue on Friday and likely to be completed by evening. The small aircraft made several sorties refuelling intermittently collecting the radio waves from the Localizer installed at the far end of the runway and very close to the National Highway No.5. The other equipment installed is a Guide Path installed at the touch-down point for any aircraft.

When any aircraft approaches the airport it can locate both coordinates and align with them to be perfectly landing the airport even during poor visibility conditions especially in winter months, when many of the airlines have been changing their schedules.

There is also a great demand for early morning flights and this system would prove a boon for the Gannavaram Airport in the coming monsoon and winter season, Airport Authority of India Airport Director C. Pattabhi told The Hindu .

The ideal angle for landing was 3 degrees and the ILS can guide an aircraft up to 200 feet above the touchdown point from where the pilot takes help of his visual assessment.

The visibility requirement for various types of aircraft, which is between 2400 meters and 2800 meters for landing, now will come down to 1200 meters, said Air Traffic Control Manager Jagdish Singh.

The Airport Director will send a report to the Director General of Civil Aviation on the trials being carried out by the AAI team, which will then give permission for the commercial airline pilots to test it for some days and then give them the report for final approval from the DGCA. This entire process might take about 20 days.

Then regular calibration would be done every six months.

Aircraft landing will then turn unidirectional once the aircraft begin using the ILS and they would take the help of VHF Omni Range (VOR) to come in line with the landing direction at 12 nautical miles. Precision Approach Path Indicators then help the airplanes land in the right angle finding the central line and runway end lights during night.
