New navigation aid at airport soon for safer landings

Patna: Flight operations from the city airport will get safer as a new navigational aid is likely to be installed by March 31. Work on replacing ageing equipment in the existing Instrument landing System (ILS) will commence within a few months.

Airport director Bhupesh CH Negi said in a statement issued on Friday that new Doppler Very High-Frequency Omni Range (DVOR) will be operational by March. “The state government has recently given working permission to the Airports Authority of India (AAI) to start work on 16.5 acres of land located outside the southern side of the airport boundary wall, which has been identified for installation of the DVOR as well as an isolation bay,” Negi said.

He added, “We have targeted to install the new DVOR by March 31, following which its calibration will get done. The final date for commissioning of the new DVOR will be announced accordingly.”

On the DVOR, the airport director said, “The DVOR equipment guides the pilots to approach an airport by radiating navigational signals up to approximately 600kms. Additionally, the DVOR also helps the pilots during the landing process.”

The cost of the DVOR equipment is Rs3cr and the total expenditure for the electrical and civil engineering work for its installation is expected to be Rs2.36 crore.

The airport director claimed that the work on the ILS is likely to start in a few months. The ILS consists of a localiser and a glide path, which help pilots identify the position of the runway at the time of landing.

The current ILS at the Patna airport is Category 1, which is known as CAT-I ILS and the director claimed that it will remain in the same category. “We are just going to change the equipment- localiser and glide path,” Negi said.

He further said, “The cost of the ILS equipment is approximately Rs 4crore. The total cost involved in electrical and civil engineering related works of ILS is estimated to be around Rs 4.36crores.”
