Since India's obstruction in the operation of the radio navigation system (ILS) that guides the ship from the surface to land safely, 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) due to the problem of reduced visibility due to snow/cold, the problem of suspension of international flights 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's level, the Instrument Landing System (ILS) ) when India does not support the operation 

Nepal has decided to implement a satellite-based RNP-AR (Required Navigation Performance Authorization Required) system to guide ships during landing.

The ship will land at Bhairahawa from January 10 through the satellite-based RNP-AR system. Along with this, the minimum visibility requirement of 2200 meters for the landing of ships has 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,' Pradeep Adhikari, director general of the authority, said at the aviation meet organized in the capital on Friday, 'The problem of no flight due to bad weather in Bhairawa will be eliminated.' 

This system is designed by Nepalese technicians this time. It was led by Rajendra Singh Nayak, Deputy Director of the Authority. The authority signed a four-year contract with France's Civil Aviation Authority in June 2080 for technical assistance and air safety enhancement.

'Before this, 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. According to the international rules, the authority has published it in 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 rather than ground base. He said that the connection of RNPA owner 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 cockpit 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 a country like Nepal with environmental and geographical complexity," Deputy Director Nayak said,   "It is unique." Regarding this, the pilot must have trained in the training equipment simulator, which has the cockpit of the mandatory ship, but not only for flying. At the 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 Bhairahawa's runway in a simulator. Then they get the training approved by the Civil Aviation Office of their country. . Send the letter there to the Civil Aviation Office of Nepal. Since this rule will be implemented only after that, 42 days time has been kept. 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 aircraft landing from the west has been landing with a minimum visibility of 1700 meters. To the west is the RNPAR-APCS system to guide ships to land. Both of these systems are not as accurate as RNPAR.

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

The excitement was added when five airlines started international flights from Bhairahawa while they were moving in stages for the operation of the airport. Gautam Budh International Airport has informed that the airline company has canceled the flight due to bad weather. Industrialists say that their suspicions regarding the continued 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 had landed flights until December 12th. After that, the airport said that the flight was stopped due to low visibility. Every airline has scheduled flights for a limited period. After the expiry of the flight period from Bhairahawa, they suspended the service.

Thai AirAsia, which used to fly two days a week, was flying only 1 day recently. Thai, which had one flight on Thursday (December 26), has now announced that it will fly on January 2. Bajracharya says that the issue of when regular flights will start has not been decided yet. 

 From January 1, Thailand is going to start online visa. Therefore, he said, the matter 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 airport's notification, Jazeera stopped the flight and said that it will not take off until the weather is bad. Bajracharya said that because all the flights were in the afternoon, the airline company had stopped the flight for renovation 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.' Fly Dubai is scheduled to fly again on January 13 is Even though Nepal Airlines is making regular flights, those who bring passengers from Kathmandu do not open the door at Bhairahawa, nor do they get to fly by cutting passenger tickets.
