Since India's obstruction in the operation of the radio navigation system (ILS) that guides the ship from the surface to land safely remains, the satellite-based RNP-AR system, which is considered more advanced than this system, is going to be implemented in Bhairahawa.

In the three months of winter (November/February/January), the problem of suspension of international flights due to the problem of reduced visibility due to snow/cold has been seen continuously for three years, even though Nepal requested India from the technical level of the Nepal Civil Aviation Authority and even from the Prime Minister, India supported the operation of the Instrument Landing System (ILS). Otherwise, Nepal will use satellite-based RNP-AR (Required It has been decided to implement the Navigation Performance Authorization Required) system.

Ships will land at Bhairahawa from January 10 through the satellite-based RNP-AR system. The minimum visibility requirement of 2200 meters for ships entering Chitwan East has now been reduced to 900 meters. 'Now it will be possible to land a plane in bad weather with a visibility of up to 900 meters,' the director general of the authority, Engineer Pradeep Adhikari, said at the aviation meet organized in the capital on Friday, 'the problem of no flight due to bad weather will be eliminated this time.'

this time Designed by Nepalese technicians. It was led by Rajendrasinh Nayak, deputy director of the authority. The authority signed a four-year agreement with France's Civil Aviation Authority in June 2080 for technical assistance and air safety enhancement.

'Nepal did not have technical knowledge about the system for landing ships. The Chinese in Pokhara and Airbus in collaboration with Qatar Airways in Kathmandu designed the procedure of the approach system," said the Director General, "For the first time, Nepali technicians have designed the RNPAR system . According to the international rules, we have published this in the AIP on November 27 for the proper information of those concerned with aviation.

The official says that many countries have gone to the technology of landing ships based on satellite instead of ground base. He said that the connection of RNPA in Bhairahawa has increased the negotiation power of the state.

According to Deputy Director Rajendra Singh Nayak, who is also an ATC, the ILS system, which has been in use since the 1990s, has been installed in the cockpits of all aircraft, from small TwinOtters to large jets. But since RNP-AR developed after 2004 is satellite-based, it is not available on most ships . "The RNPAR system is a boon for airports in countries like Nepal with environmental and geographical complexity," Deputy Director Nayak said, "It is unique." In this regard, the pilot must have trained in the training equipment simulator that has a cockpit of the ship, but not only for flying. At an airport with RNPAR system, only the pilot who has received this training should land the plane.'

Why is the landing system of Bhairahawa airport in AIP implemented only after 42 days, why not immediately? In this regard, Nayak says, "Airline companies that are flying at Bhairahawa during this period but are unable to fly due to reduced visibility, pull that data and take training from instructor pilots at the official training center to land on the runway of Bhairahawa in a simulator." They then get that training approved by their country's Civil Aviation Office . He submits the letter there to the Civil Aviation Office of Nepal. Since this rule will be applied only after that, 42 days time has been set . For this reason, this system will be implemented in Bhairawa only from January 10.

As the ILS system is not operational in Bhairawa, the ships entering there from Simra have been landing with the help of VOR-DME system based on radio waves with a minimum visibility of 2200 meters. The ships landing from the west side have been landing with a minimum visibility of 1700 meters . There is an RNPAR-APCS system to guide ships to the westbound landing. Both of these systems are not as accurate as RNPAR.

Since then, the stakeholders here have been disappointed again after the international flights started by five airline companies at Gautam Budh International Airport in Bhairahawa, Ruppandehi, became irregular due to bad weather.

The excitement was added when five airlines started international flights from Bhairahawa while the phased movement was being carried out for the operation of the airport. They were disappointed after the flight became irregular again. The Gautam Budh International Airport has informed that the airline has suspended the flight citing bad weather. Industrialists say that their suspicions regarding the continuous operation of the airport have been confirmed after the airline companies operating international flights have stopped their regular flights.

The airline that operated regularly last November landed flights until December 12th. After that, the airport said that the flight was stopped due to low visibility. Every airline had fixed flight schedule for a limited period . After the flight period from Bhairahawa ended, they suspended the service . Thai AirAsia, which used to fly two days a week, was flying only 1 day recently. Thai, which flew once on Thursday (December 26), now says it will fly on January 2. According to Bajracharya, the issue of when regular flights will start has not been decided.

From January 1, Thailand is about to start online visa . Therefore, he said that the issue of the arrival of the plane will be decided by the visa system. Bajracharya said that since Qatar Airways has completed its trial period, it has not announced the new schedule. Qatar conducted a test flight from 15 November to 30 November . Jazeera Airways has scheduled to resume flights from February 1.

After the notification of the airport, Jazeera stopped the flight and said that it will not take off until the bad weather. Bajracharya said that because all the flights are in the afternoon, the airline company has stopped the flight for renewal rather than the effect of the weather. "We couldn't tell them to fly at a time other than their demand," he said, "after the renovation, they will definitely fly, the cold wave will be 2/3 days, except for that period, the weather will not be a problem."
