Yeti Airlines ATR-72 crashes in Nepal's Pokhara; all the lives lost

A 72-seat passenger ATR-72 aircraft belonging to Yeti Airlines tragically crashed upon landing at Pokhara International Airport in Nepal's Kaski district on Sunday, January 15. The aircraft was 15 years old. It was Nepal's worst crash in nearly five years.

At least 67 people are confirmed dead after a plane carrying 72 people crashed in Nepal on Sunday, police said. "Thirty-one (bodies) have been taken to hospitals," police official AK Chhetri told AFP, adding that 36 other bodies were found in the gorge where the aircraft crashed. 

There were 5 Indians apart from 4 Russians, 1 Irish and 2 South Korean nationals among the passengers. The Indian nationals have been identified as Abhisekh Kushwaha, Bishal Sharma, Anil Kumar Rajbhar, Sonu Jaiswal and Sanjaya Jaiswal, a Yeti Airlines official said.

Yeti Airlines ATR-72 crashes in Nepal's Pokhara; all the lives lost

According to the Civil Aviation Authority of Nepal (CAAN), Yeti Airlines' 9N-ANC ATR-72 aircraft took off from Kathmandu's Tribhuvan International Airport at 10.33 am and crashed at the Pokhara airport at around 11 am. Emergency rescue operations are currently being conducted at the airport. A total of 72 people - 68 passengers and 4 crew members - were on board the ill-fated flight, as confirmed by a spokesperson for Yeti Airlines.

The Yeti Airlines flight 9N-ANC ATR-72 was on its third sortie since Sunday morning. It first flew from Kathmandu to Pokhara and back to Kathmandu earlier in the day. The Yeti Airlines aircraft took off from Kathmandu's Tribhuvan International Airport at 10:33 am. While landing at the Pokhara airport, the plane crashed on the bank of the Seti River between the old airport and the new airport.

Flight tracking website FlightRadar24 said the Yeti Airlines aircraft was 15 years old and equipped with an old transponder with unreliable data. Yeti Airlines has a fleet of six ATR72-500 planes, according to its website. Yeti describes itself on its website as a leading domestic carrier of Nepal.

Images and videos of the crash posted on social media showed smoke billowing from the site.

Nepalese Prime Minister Pushpa Kamal Dahal called an emergency cabinet meeting following the crash and directed effective rescue operations. The Nepal government has also formed a five-member commission of inquiry to probe the plane crash. The Nepal government has also formed a five-member commission of inquiry to probe the plane crash.

Images and videos of the crash posted on social media showed smoke billowing from the site. As per reports, the airport was closed temporarily owing to the incident. Pokhara, in central Nepal, is a lakeside tourist mecca below the Annapurna mountain range.

The passenger plane reportedly crashed just ten seconds before landing. According to the Air Traffic Control (ATC) staff, the runway of Pokhara is built in the east-west direction. Initially, the pilot asked for a landing in the east and permission was granted. However, later on, the pilot asked for permission to land in the west direction and was given permission again. But the plane crashed ten seconds before landing.

The new airport, Nepal's third international airport, built with Chinese assistance, was inaugurated only days ago, on January 1, 2023.

It was a clear day in the Pokhara valley and weather conditions were not all adverse. The crashed aircraft was an ATR-72, an aviation workhorse in the mountainous region. The cause of the crash will only be known after data from the blackbox is analysed. The new airport, Nepal's third international airport, built with Chinese assistance, was inaugurated only days ago, on January 1, 2023. Rescue operations are underway and the airport has been closed for the time being.

The weather was clear, said Jagannath Niroula, Nepal's Civil Aviation Authority spokesman. "Thirty bodies have been recovered and sent to hospital," Niroula said, as reported by Reuters. "Another 14 bodies are still lying at the crash site and authorities are bringing in a crane to move them," he said.

The Himalayan country of Nepal, home to eight of the world’s 14 highest mountains, including Everest, has a record of air accidents. Its weather can change suddenly and airstrips are typically sited in difficult-to-reach mountainous areas.

Last May, a Tara Air flight carrying 22 people crashed into a Himalayan mountain at an altitude of about 14,500 feet. That was the country’s 19th plane crash in 10 years and its 10th fatal one during the same period, according to the Aviation Safety Network database.

In 2016, all 23 people aboard were killed when a plane of the same airline flying the same route crashed after takeoff. In March 2018, a US-Bangla Air crash occurred at the Tribhuvan International Airport, killing 51 people on board.

A Sita Air flight crashed in September 2012 while making an emergency landing at the Tribhuvan International Airport, killing 19 people. A plane flying from Pokhara to Jomsom crashed near Jomsom airport on May 14, 2012, killing 15 people.

Nepal's air industry has boomed in recent years, carrying goods and people between hard-to-reach areas and foreign trekkers and climbers. But it has been plagued by poor safety due to insufficient training and maintenance. The European Union has banned all Nepali carriers from its airspace over safety concerns since 2013.

The new L band digital aeronautical communications system (LDACS), a revolutionary air traffic control (ATC) communications system that greatly improves bandwidth and enables contemporary IP-based communications, has been developed by Rohde & Schwarz in collaboration with research partners. In order to become the next global standard, it is about to supersede the current VHF digital link (VDL) mode 2 in civil aviation.

Compared to VDL mode 2, LDACS provides data throughput that is up to 200 times quicker. Particular frequencies in the L band designated for flight communications are used by LDACS. In order to minimize out-of-band emissions and ensure trouble-free operation with other aircraft equipment operating in that band, it employs interference suppression algorithms.

" Modern aviation demands the secure exchange of data. LDACS reliably enables high data throughput that is secured with encryption. It can support a wide variety of new applications, such as the data connections airlines need for flight crews to efficiently plan fleet operations "- Thomas Bögl, Director of Technology and Studies at Rohde & Schwarz, explains

The extremely simple road to a market launch is another advantage of LDACS. New environmentally friendly navigation techniques will also benefit from dependable and secure data transfer through LDACS. The idea is to choose air routes with exact three-dimensional coordinates and strict time constraints. Aircraft can be dynamically routed around airports using the 4D trajectory idea to avoid noise protection zones.

A program for aviation research called LuFo has been developed by the German Federal Ministry for Economic Affairs and Climate Action for LDACS. The programmer is Rohde & Schwarz. To advance LDACS technology, more project partners like the German Aerospace Center (DLR) are working together. The International Civil Aviation Organization (ICAO) and the working groups in the program are working together to develop and execute flight acceptability standards.

A technological foundation has been laid as part of the recently established LuFo project "Pave the Way to Digital Aeronautical Communications" (PaWaDACs), enabling the product development of LDACS ground equipment and LDACS aerial equipment beginning in 2025. The equipment is anticipated to go on sale in 2028. Rohde & Schwarz will have a competitive advantage over other LDACS suppliers due to its early involvement in the LuFo project.

Rohde & Schwarz

Beginning in early 2022, the PaWaDACs project has been in progress. It focuses on establishing a realistic test installation and miniaturizing equipment demonstrators at two locations run by the German air navigation service provider (DFS). Once finished, the essential technological foundation for future LDACS systems will be established. New civil aviation product development will have a strong foundation.

European planemaker Airbus said it had withdrawn from a U.S. government-named panel reviewing Boeing’s safety processes and how they influence Boeing safety culture after two fatal 737 MAX crashes in recent years killed 346 people.

The Federal Aviation Administration's (FAA) panel named last week includes MIT lecturer and aerospace engineer Javier de Luis whose sister was killed in a MAX crash, as well as experts from NASA, the FAA, labour unions, Southwest Airlines, American Airlines, United Airlines, GE Aviation and FedEx Express.

Among those named was James Tidball, head of the certification for Airbus Americas. Airbus said in a statement to Reuters it appreciated the FAA's recognition of Tidball's impartiality concerning safety but given "the panel’s focus on a particular (Original Equipment Manufacturer, Tidball)... has decided to recuse himself from this working group."

Airbus leaves the US FAA panel reviewing Boeing safety culture

The panel, which Congress required under a 2020 law to reform how the FAA certifies new airplanes, has nine months to complete its review and issue findings and recommendations. Congress directed the agency to appoint a panel by early 2021, but the FAA missed that deadline.

A 2020 U.S. House report said the MAX crashes in 2018 and 2019 "were the horrific culmination of a series of faulty technical assumptions by Boeing's engineers, a lack of transparency on the part of Boeing's management, and grossly insufficient oversight by the FAA."

Boeing last week declined to comment on the panel, but previously emphasized it has significantly reformed its safety culture after the MAX crashes cost it more than USD 20 billion.

The FAA continues to subject Boeing to enhanced oversight, inspecting all new Boeing 737 MAXs and 787s before they can be delivered.

Last month, Congress voted to lift a December 27 deadline imposing a new safety standard for modern cockpit alerts for two new versions of the 737 MAX aircraft that could have put the future of those new models at risk.

Air traffic to and fro Kashmir was affected on Friday as several flights were cancelled due to snowfall across the valley, officials said here. The fresh snowfall started early in morning and continued till the last reports came in.

While the higher reaches of Jammu and Kashmir experienced moderate to heavy snowfall, the areas in the plains received light to moderate snowfall.

"The flight operations at Srinagar airport have been suspended till further notice due to continuous snowfall and low visibility," the Director, of Airport Authority of India (AAI), Srinagar Airport, Kuldeep Singh, told PTI. He said the flight operations took place in the morning but had to be suspended after 10 am due to low visibility and snowfall.

Air traffic in Kashmir affected as several flights cancelled due to snowfall

Most of the airlines, including, Air India, AirAsia, IndiGo, SpiceJet and Vistara, have cancelled all their remaining flights for the day due to the bad weather, Singh said. Other airlines also have cancelled several of their flights.

All flights to and from Srinagar were initially suspended and later cancelled after 10 am due to continuous snowfall and poor visibility, an airport official said. The air traffic will resume after the weather improves. The passengers booked on the cancelled flights would be accommodated by the respective airlines in the next available flight at no extra cost, airport authorities said.

The inclement weather has also resulted in the closure of the Srinagar-Jammu national highway - the only all-weather road connecting Kashmir valley with the rest of the country. The highway was closed for traffic due to landslides at Mehar, and slippery conditions of the road. The officials said road clearance operations were going on, but continuous snowfall and rain were making the job difficult.

Continuous progress is the goal when it comes to safety. Airbus is always looking for new inspiration to develop proactive solutions that can raise performance and safety.

Representative | Airbus

And what better place to get inspiration from than the magnificent natural world? Airbus's "sharklet" wing-tip design, which decreases drag, and the fello'fly demonstrator, which imitates the formation flying of snow geese for better performance, are just a few of the innovative solutions it has developed as a result of biologically inspired engineering, also known as "biomimicry".

Airbus

The recent biomimicry demonstration from Airbus, called DragonFly, was motivated by the common, humble "dragonfly."

A dragonfly's exceptional vision, 360-degree vision, and ability to recognize landmarks enable it to clearly determine the limits of its territory. Similar to how the systems the company is researching and developing review and recognize landscape elements to help the aircraft "see" and safely maneuver in its surroundings.

Especially in the context of emergency operations, these advances may add another level of safety to aircraft. In the odd event that a crew loses control of the plane, DragonFly can reroute the flight to the closest suitable airfield and help with a secure landing.

Decoding "DragonFly"

When it comes to derisking emergency operations, DragonFly could be a game-changer. Its three main areas of focus each support automated yet thoughtful decision-making by combining data collected during flight with a massive corpus of flight information.

Representative | Royal Aeronautical Society

In order to help assure safe flight and landing, DragonFly provides a solution. The onboard system recognizes a problem and automatically chooses the best airport to guide the aircraft toward if the crew is unable to manage it.

Of course, flight routes and outside variables are complicated and dynamic. A dragonfly explores its surroundings before adjusting its course. Similar to this, the DragonFly prototype makes its landing decisions by taking into account the environment, including flight lanes, topography, and weather. However, in contrast to a typical dragonfly, the DragonFly additionally gains from a continuous line of communication between the aircraft and both Air Traffic Control and the airline's Operations Control Center to guarantee a secure and well-coordinated approach.

L'Usine Nouvelle | Representative

In the same way that dragonflies can recognise landmarks that help them to define boundaries, our demonstrator is equipped with cutting-edge sensing technology and software, capable of managing in-flight and landing operations. The DragonFly demonstrator has been made possible through cooperation within the Airbus engineering community and with our trusted external partners, and we look forward to the insights that this final stage of testing will deliver- Isabelle Lacaze, Head of DragonFly demonstrator, Airbus UpNext

Possible safe and automated landing at any airport in the world

Airbus has developed a system that combines sensors, computer vision algorithms, and reliable navigation calculations to greatly simplify landing in poor visibility or challenging weather circumstances because a dragonfly's eyesight functions much more swiftly than a human's.

The technologies were able to help pilots throughout the flight test campaign when handling a simulated disabled crew member event, as well as during landing and taxiing operations. The aircraft was able to construct a new flight trajectory plan and interact with both Air Traffic Control (ATC) and the airline operations control center while taking into account external factors like flight zones, topography, and weather conditions.

These advancements open the door for an automatic landing (if required) or can be tailored to the pilot's flying abilities to relieve them of extra steps in an emergency or critical circumstance.

In the future, DragonFly's advancements may make it possible for the plane to land at any airport in the world, regardless of whether the airport has the ground equipment necessary for automatic landing.

The crew of the DragonFly demonstration can manage taxi guidance and instructions, including navigation and surveillance, with the use of pilot assistance technology, giving them up to concentrate on other crucial responsibilities.

Airbus

Airbus has started testing new, on-ground, and in-flight, pilot assistance technologies on an A350-1000 test aircraft.

Moving forward

The final three months of DragonFly's testing phase have already begun. Through these test flights, Airbus UpNext will be able to upgrade or validate the technology in order to incorporate advancements into the next programs.

Along with these features, Airbus UpNext is starting a project to develop the newest computer vision-based algorithms for improved landing and taxi assistance.

Cooperation between Airbus divisions and outside partners, such as Cobham, Collins Aerospace, Honeywell, Onera, and Thales, allowed for the execution of these tests. The French Civil Aviation Authority (DGAC) provided some funding for DragonFly as a part of the French Stimulus plan, which is a component of the European Plan, Next Generation EU, and the France 2030 plan.

The National Company Law Tribunal (NCLT) on Friday, January 13 allowed the ownership of Jet Airways to be transferred to the Jalan Kalrock Consortium (JKC), which had won the bid to resurrect the grounded carrier in 2021.

This comes as the consortium has appealed to the Supreme Court against a separate ruling by the National Company Law Appellate Tribunal (NCLAT) directing it to clear unpaid provident fund dues of INR 250 crore to employees, said multiple people aware of the development, highlighting the legal hurdles that remain for the new owners.

An NCLT division bench of justice PN Deshmukh and technical member Shyam Babu Gautam allowed JKC’s seek the transfer of Jet's ownership in an oral order. The ownership currently vests with the monitoring committee comprising Jet's lenders, JKC executives and the court-appointed resolution professional.

The court gave its approval despite lenders' contention that JKC had not fulfilled all conditions--including securing Jet's domestic flight slots and international traffic rights—as per the resolution plan, which is effective November 18.

The resolution applicant usually has 180 days to clear all dues to creditors but the NCLT has acceded to JKC’s demand that this is extended. It has until May 2023 to clear all dues to lenders, other creditors and workers.

The NCLT rejected an oral demand by the lenders to stay in the operation of the Friday order for two weeks so that they can challenge the ruling in the NCLAT. JKC has said it will spend INR 1,375 crore - INR 900 crore as capital infusion and INR 475 crore paid to creditors. Of that, INR 380 crore will go to financial creditors. JKC is to have an 89.79% stake while 9.5% will go to lenders.

“The NCLT order implies that the airline’s handover and distribution are segregated,” the person said. “The standoff between lenders and the resolution applicant on payment of uncleared dues to employees delayed the handover of the airline.”

Naresh Goyal founded Jet Airways, once India's biggest private carrier, stopped operations on April 17, 2019, unable to cope with its financial liabilities. It was taken to bankruptcy court by the airline's lenders. JKC's plan was approved by the NCLT in June 2021. Since November 2022, there has been a tussle between lenders and JKC over unpaid dues.
