Qantas to Replace its B717 Fleet with A220s

Qantas, one of Australia's leading airlines, is set to bid farewell to its Boeing 717 aircraft, signaling the end of an era in Australian aviation. For many years, these iconic aircraft have played an important part in QantasLink's regional operations. The Boeing 717s will be gradually replaced with the more fuel-efficient and modern Airbus A220 aircraft as part of the ambitious "Project Winton" fleet renewal programme.

Boeing 717 Jets of Qantas: A Legacy in Australian Aviation

Australia's First Boeing 717

The Boeing 717 is significant in Australian aviation history since it was the first of its kind to be registered and operated in the country. Its inclusion in the Qantas fleet heralded a new era in regional air transport. Because of the aircraft's strong structure, efficiency, and adaptability for short-haul flights, it was a suitable option for QantasLink's operations.

The Boeing 717 fleet of QantasLink

QantasLink has established a fleet of 20 Boeing 717 aircraft over the years, servicing various rural locations around Australia. These aircraft have served as the network's backbone, providing dependable and efficient service to customers travelling to smaller airports and regional centres.

The Boeing 717's Role in Qantas Operations

The Boeing 717 has played an important part in Qantas' operations, swiftly and pleasantly transporting passengers from large cities to remote locations. Because of its short take-off and landing capabilities, as well as its ability to operate from smaller airports, it has proven to be a great asset for QantasLink.

Current Scenario

The departing 717 (registered VH-NXI) has a particular role in the Qantas Group's contemporary history, having flown Jetstar's first trip between Melbourne and Launceston in May 2004. For the past 15 years, the aircraft has also flown on regional and domestic routes for QantasLink. Over the last two decades, it has completed over 29,000 flights and securely transported over 1.6 million passengers for both Qantas and Jetstar. Blue Mountains, named after a world-heritage-listed national park in New South Wales, is scheduled to depart Australia in mid-June before being sold to another large airline. It is the third 717 to depart the airline's fleet, and due to its limited range, the flight to its new owner in North America would require eight fuel stops, including Cebu, Sapporo, and Anchorage. The departing 717 was flanked at Sydney Airport by two new additions to the fleet: a Boeing 787 Dreamliner and a Jetstar A321neo LR. The next-generation aircraft are part of a massive fleet renewal initiative that will see the Group get a new aircraft every three weeks on average for the next few years. The new aircraft will assist Qantas and Jetstar in restoring capacity and expanding their networks while decreasing emissions and enhancing efficiency.

The Qantas Group has recovered to about 100% of pre-COVID domestic flying levels through a combination of new arrivals and standby aircraft returning to service, and it intends to restore 100% of international flying by March 2024. Alan Joyce, CEO of Qantas Group, joined pilots and crew at Sydney Airport to bid farewell to the 717 and welcome the new aircraft to the fleet. "It's the end of an era for these Boeing 717s, which have played a crucial role in connecting Australians across our domestic and regional networks for more than two decades," Mr. Joyce said. "It's fitting that the first 717 to be registered in this country is giving way to another brand-new fleet type, the A220, which has twice the range of the 717s and can open up new domestic and short-haul international routes." "Qantas is in the early stages of the largest fleet renewal programme in its history, with up to 299 narrowbody aircraft scheduled to be delivered over a 10-year period, in addition to the A350s that will operate our Project Sunrise flights." It is a really exciting time for both our personnel and our clients, as these new planes open up new opportunities and open up new locations. "We've already received four new aircraft this year, and we expect to receive eight more before the end of the year." "The new planes we're getting are far more capable than the planes they're replacing." They can fly longer distances while being considerably quieter and more efficient, while still offering a terrific experience for our customers."

Transitioning to the Airbus A220

Qantas has chosen the Airbus A220 as the replacement for the Boeing 717 as part of Project Winton. The A220 is a cutting-edge aircraft recognized for its fuel economy, range, and passenger comfort. The transfer from the Boeing 717 to the A220 will be gradual, guaranteeing the new aircraft's flawless integration into QantasLink's operations.

After a bird hit damaged its nose cone earlier today, an Air France flight between Osaka and Paris was forced to return. After the flight deck crew spotted a technical fault with the Airbus A350-900's weather radar and speedometer, AF291 declared an emergency and returned to Osaka Kansai Airport (KIX) less than three hours into its 12-hour journey. The one-year-old widebody, registered F-HTYO, departed Osaka at 11:15 a.m. JST on its way to Paris' Charles De Gaulle Airport (CDG). The crew of Air France did not become aware of the bird hit and cone damage until 11:50 JST while cruising at 35,000 feet just north of Tokyo. According to the Aviation Safety Network, AF291 elected to return to Osaka at about 12:10 JST before declaring an emergency 40 minutes later. AF291 landed successfully in Osaka at 14:25 JST, momentarily shutting down runway 24R for nearly an hour for inspection. At least 11 other flights were delayed. There were no reported injuries among the flight's 324 passengers and crew. The Ministry of Land, Infrastructure, Transport, and Tourism is presently handling the inquiry, although preliminary findings indicated a "minor" dent on the nose radome and broken pitot tubes. F-HYTO remains on the ground at Osaka Kansai, with local media reporting that the aircraft is undergoing minor maintenance at the terminal.

Precautions and Countermeasures Against Bird Strikes

Aviation authorities, airports, airlines, and aircraft manufacturers all take safeguards and make efforts to reduce the danger of bird attacks.

Programmes for Airport Bird Control

Airports frequently have specific bird control programmes in place to regulate nearby bird populations. To dissuade birds from breeding or feeding near runways and flight routes, these programmes use a variety of measures, such as habitat alteration, deterrent devices, and bird hazing.

Features of Aircraft Design

Specific design characteristics are used in aircraft to improve bird attack resistance. Reinforced windscreens, stronger materials for leading edges and key regions, and engine bird ingestion avoidance techniques are among them. These design modifications lower the impact of bird strikes and reduce the likelihood of critical damage.

Pilot Procedures and Training

Pilots undergo comprehensive training to deal with emergency scenarios such as bird attacks. They are taught to determine the severity of the impact, examine any damage, and make educated judgements on whether to continue the flight or return to the departure airport. There are standard operating procedures and checklists in place to help pilots deal with such occurrences safely.

Conclusion

The bird strike event that prompted Air France flight AF291 to return shows the necessity of aviation readiness, safety precautions, and good communication. While bird strikes constitute inherent dangers, the aviation industry is always working to reduce these risks through extensive training, airport bird control programmes, improved aircraft design features, and routine maintenance procedures. We can secure safer skies for everybody by better understanding the consequences of bird strikes, taking preventative measures, and encouraging teamwork.

In a move that will benefit passengers travelling to Germany, the Rajiv Gandhi International Airport (RGIA) will offer flights to Frankfurt from January. Starting from January 16, 2024, Lufthansa’s inaugural direct flight from Frankfurt to Hyderabad will be operated using a wide-body Boeing B787-9 Dreamliner. The last time Lufthansa served Hyderabad from Frankfurt was back in October 2011, so nearly twelve years later, the carrier is finally returning the service. The aircraft will feature 26 business class seats, 21 premium economy seats and 247 economy class seats. Lufthansa currently has five Boeing 787-9 Dreamliners in its fleet with a further 34 on order.

Flight Schedule

The flight duration will be approximately 8.30 hours, and it will operate between Frankfurt and Hyderabad three times a week. Departures from Frankfurt to Hyderabad are scheduled for Tuesdays, Fridays and Sundays, while return flights from Hyderabad will take place on Mondays, Wednesdays and Saturdays. This new route opens up exciting possibilities for travellers from Telangana and neighbouring regions, providing convenient access to destinations across Europe.

The inaugural flight to Hyderabad will take off from Frankfurt at 10 A.M. and will reach Hyderabad at 11 P.M. For the return journey, the flight will depart from Hyderabad at 1 A.M. and reach Frankfurt at 6:10 A.M.

With the new service, travellers can now plan their vacation and explore the picturesque terrain, treasure trove of historical sites, vibrant European cities, world-class museums, galleries and much more. Additionally, Frankfurt as a major aviation hub of the world will connect its passengers to multiple cities in North America, including USA and Canada.

GHIAL said that the new route will connect travellers from Telangana and the nearby catchment regions to Europe. “Frankfurt as a major aviation hub of the world will connect you to multiple cities in North America including USA and Canada as well,” it added.

Lufthansa's Flights to Bangalore

One of the fastest-growing aviation markets, India's International traffic is handled largely by foreign carriers, and Lufthansa is taking it further. In total, Lufthansa's footprint in India would tally to five destinations including Delhi, Mumbai, Chennai, Bangalore and now Hyderabad.

The German airline recently firmed its plans on reviving the Munich-Bengaluru route for the winter of 2023, which would be operated on the Airbus A350. British Airways, Air France, and KLM all operate directly from Europe into Bangalore, alongside carriers from the Middle East, so having Lufthansa poised to operate from its two German bases will further solidify its presence, serving the Indian city with a population of over 13 million.

Lufthansa’s Relations with India

Lufthansa has got a long-term vision to strengthen its footprint in the Indian market by catering to the growing population of young working professionals through this expansion. “The brand intends to make the best of India’s s untapped growth opportunity by providing consumers with the most premium travel experiences during their international trips, be it for business or leisure,” a press release said.

The airline had planned to start the service in 2020 before the outbreak of the COVID-19 pandemic hit the world. Lufthansa operates about 80 flights a week between India and Germany. Lufthansa has ordered more than 200 aircraft to be the most modern fleet operating in Europe in the coming years.

German carrier Lufthansa pitched for the liberalisation of bilateral air traffic rights. Lufthansa's comment comes in the wake of Indian authorities blocking any extension of bilateral rights to foreign airlines to promote Indian carriers. "The right assumption is that it has some kind of protectionism. In the long run, I think airlines would be better off if they do partnerships and if they understand that not one airline can generate a global network. It is simply impossible, "

Indian carriers will be better off if the restriction on bilateral rights is eased in the long term and if passengers have more choices for air travel, Harry Hohmeister, head of global markets & network, Lufthansa Group Airlines, said on Thursday, April 27.  

For an airline to operate a scheduled flight between two countries, there must be a “bilateral air services agreement” in place, which is negotiated and signed by both countries. This agreement outlines the “bilateral rights”, which determine the number of flights or seats that the airline is allowed to operate per week between the two countries.  

Currently, Lufthansa operates 54 flights a week which will be increased to 56 by June end and after adding more services, flights are expected to increase to over 60 per week. Lufthansa Group has had a presence in the Indian market for more than 90 years.

About Lufthansa

Deutsche Lufthansa AG, commonly shortened to Lufthansa, is the flag carrier of Germany. When combined with its subsidiaries, it is the second-largest airline in Europe in terms of passengers carried after ultra-low-cost carrier Ryanair. Lufthansa is one of the five founding members of Star Alliance, the world's largest airline alliance, formed in 1997.

Today, millions of passengers can fly throughout the world with confidence, knowing that their journey is safeguarded by stringent safety precautions. These safety precautions are the result of the unwavering work of individuals like Don Bateman, who have committed their entire lives to improving aviation safety.

The Evolution of Aviation Safety

The Importance of Air Travel Safety

In the aviation sector, safety has always been the top concern. As the number of air travelers expanded, so did the necessity for strong safety measures to avoid mishaps and maintain passenger safety. Governments, regulatory agencies, and aviation experts have all worked relentlessly to establish an environment in which flying is not only efficient but also extremely safe.

Advancements in Technology and Systems

The growth of aviation safety is inextricably linked to technological improvements. Engineers and developers have created a plethora of methods and technologies to reduce hazards and improve safety throughout the years. Because of these developments, flying is now one of the safest modes of transportation, exceeding even more conventional modes like car or rail travel.

Don Bateman: The Creator of GPWS

Air travel has become an essential part of the way we live, connecting people and cultures all over the world. With millions of flights taking place each year, aviation safety is of the utmost significance. Flying nowadays is safer than ever before, thanks to ongoing technological developments. The Ground Proximity Warning Device (GPWS), designed by Don Bateman, is an essential security measure that plays an essential part in safeguarding the well-being of passengers and crew. Don Bateman departed on Sunday, May 21st, at the age of 91, leaving behind a legacy that has transformed aviation safety. Bateman was born in Saskatoon, Saskatchewan, and graduated from the University of Saskatchewan as an electrical engineer. While his career began at a telephone equipment firm, he later relocated to Renton and accepted a position at aviation behemoth Boeing, where he worked on the avionics of the Boeing 707.

Soon after, Bateman joined United Control, a Seattle-based aviation electronics manufacturer that is now part of Honeywell. This is where Bateman assembled a small team to focus only on testing and developing aviation safety measures. Bateman and his colleagues went on to develop the GPWS, which is widely regarded as one of the most important air safety systems. One of the most prevalent forms of aviation mishaps in the 1960s and 1970s was aeroplanes crashing into terrain, often known as Controlled Flight into Terrain, or CFIT. Bateman and his colleagues set out to prevent similar mishaps, and they succeeded with the introduction of GPWS. However, the team led by Bateman continued to work on the system for decades thereafter to enhance it, making it safer and more technologically advanced. Over the years, Bateman has played an instrumental role in making air travel safe, and he is recognised as the gentleman who has saved countless lives in aviation history. Bateman won several accolades for his efforts during his life, including President Barack Obama's National Medal of Technology and Innovation.

The Vitality of GPWS in Aviation Safety

How Does GPWS Work?

GPWS monitors the aircraft's location relative to the ground employing a network of sensors and data analysis algorithms. GPWS can identify potential hazards such as rapidly decreasing altitude, proximity to terrain, or approaching obstructions by continually analyzing altitude, speed, and other important factors. The system collects data from numerous aircraft systems, including the radio altimeter, machmeter, air data computer, ILS, landing gear/flap position, and navigation systems. When a dangerous condition occurs, GPWS sends out visual and auditory alerts to warn pilots and prompt corrective action.

GPWS Features and Functions

Each mode has a first boundary that, if crossed, informs the pilot. However, several of the more important modes (one, two, and four) include a secondary boundary that, if exceeded, causes the system to issue a warning call to the pilot, signaling that quick action is required.

Over time, a seventh mode was added, in which the GPWS system analyzes data from the Air Data Computer to detect any signals of probable wind shear in the aircraft's proximity. If probable wind shear is identified, the system issues a direct warning call out to the pilot, "Windshear," so the pilot may be prepared to take any necessary steps.

Though the system cannot identify the specific position of the wind shear, it is beneficial for pilots to be aware of its existence, particularly during the landing phases of a flight, when an early warning may allow the pilot to be better prepared to respond or execute a go-around, as required.

Other Aviation Safety Innovations 

Additional Safety Systems and Technologies

While GPWS is a cornerstone of aviation safety, the industry is always looking for ways to enhance it. Engineers and researchers are working on enhanced safety systems and technologies, such as:

Traffic Collision Avoidance System (TCAS): TCAS assists pilots in avoiding mid-air collisions by providing real-time information on nearby aircraft and issuing resolution advisories if necessary.

Enhanced Ground Proximity Warning System (EGPWS): EGPWS is a further sophisticated form of GPWS that includes features such as predictive terrain mapping, weather data integration, and enhanced obstacle detection capabilities.

Automatic Dependent Surveillance-Broadcast (ADS-B): ADS-B enables aircraft to broadcast and receive real-time information, augmenting situational awareness and collision avoidance.

Legacy and Prospects

Don Bateman's legacy as a pioneer in aviation safety will continue to influence the industry for many years to come. His innovation, the GPWS, has become an essential component of modern aircraft, safeguarding the safety of passengers and crew. As aviation technology advances, his achievements are guaranteed to inspire new advancements in safety systems, introducing the industry to even greater heights of safety and reliability.

Conclusion

Don Bateman's extraordinary contribution to aviation safety through the development of the Ground Proximity Warning System has left an indelible effect on the industry. His devotion, vision, and commitment to improving aviation safety have made him a real pioneer. While we grieve his death, we also celebrate the legacy he leaves behind and the numerous lives saved by his wonderful innovations. Don Bateman's work exemplifies the potential of human intellect and innovation to foster a more secure and safe aviation sector.
