How Etihad intends to combat contrails while crossing the Atlantic

During an Atlantic trip, Etihad is taking efforts to prevent contrails.

Etihad Airways and SATAVIA collaborate to implement contrail prevention for the first time on an Atlantic crossing

As part of the continuing collaboration with SATAVIA, the national airline of the United Arab Emirates, Etihad Airways, is implementing contrail prevention on a special NetZero flight during the COP27 event.

On Sunday, November 13, the airline will fly a specially designated NetZero* flight, EY130, from Washington Dulles Airport to Abu Dhabi. This flight will demonstrate the viability of net-zero commercial aviation by utilizing sustainable aviation fuel (SAF), SATAVIA contrail prevention, and other operational efficiencies.

The flight is the most recent in Etihad’s series of Eco Flights that have been conducted over the previous two years. It comes after the EY20 Sustainable Flight that Etihad conducted from London Heathrow to Abu Dhabi last year, which reduced overall climate effect by 72%.

The trip will be the first Etihad transatlantic crossing to actively manage non-CO2 climate effects from contrail generation, confronting a sustainability challenge that accounts for up to 60% of aviation’s climate footprint. This builds on Etihad’s weekly contrail prevention exercises with SATAVIA.

In addition to enabling contrail prevention in routine aircraft operations, SATAVIA undertakes post-flight climate effect analyses for conversion into future carbon credits, with a first-ever exchange via auction scheduled with Air Carbon Exchange in December 2022.

The flight is being described as NetZero rather than ‘Carbon Neutral’ as it is achieving more than off-setting the CO2 emissions. To categorize this flight as NetZero, Etihad must demonstrate the absolute maximal direct emissions reductions operations possible. This includes (but is not limited to):

Utilizing its Etihad Greenliner fleet – the Boeing 787 – with competitive fuel efficiency per passenger
Maximizing and ensuring cargo and passenger load factors to maintain efficiency
Pre-flight engine wash and aircraft cleaning for aerodynamics and engine efficiency
Use of single-engine taxiing
Intensive flight planning and direct routing, including continuous descent and reduced auxiliary power unit (APU) burn
Contrail avoidance testing with SATAVIA to reduce non-CO2 emissions and climate impact
In flight service to reduce waste production and scope 3 waste to CO2 impacts

InterGlobe Enterprises, the parent brand of IndiGo, is set to revolutionize travel in India with its upcoming air taxi service.

Scheduled for a potential launch in 2026, this innovative venture promises a seamless journey for passengers between two bustling hubs. Delhi and Gurgaon in Haryana. The forthcoming service is projected to revolutionize the daily commute, offering passengers a swift aerial journey covering the distance in a mere 7 minutes.

This remarkable efficiency contrasts starkly with the conventional 90-minute drive, underscoring the immense time-saving potential for commuters. The anticipated fare, ranging from Rs 2,000-3,000, makes this innovative mode of transport not only swift but also remarkably competitive in pricing.

At the heart of this ambitious endeavor lies a strategic partnership with Archer Aviation, a pioneer in electric vertical takeoff and landing (eVTOL) aircraft technology. Under this collaboration, Archer will supply 200 state-of-the-art eVTOL aircraft, representing an investment of US$ 1 billion. These cutting-edge aircraft, capable of accommodating up to four passengers alongside the pilot, epitomize the future of sustainable air travel.

Powered by six battery packs, Archer’s eVTOL aircraft boast rapid charging capabilities, enabling a swift turnaround between flights. With a charging time of just 30-40 minutes, these eco-friendly aircraft ensure minimal downtime, maximizing operational efficiency.

Similar services are anticipated to be introduced by the joint venture in Bengaluru and Mumbai as well. Nevertheless, the service rollout period has not yet been made public by the company. Next year, it is anticipated to get its certification. Following this, the company will start the certification procedure with the Directorate General of Civil Aviation (DGCA).

Which is bigger 777x or 787 aircraft ?

The 777X is a new series of the Boeing 777 family and is designed to be larger and more efficient than its predecessor. It features two variants: the 777-8 and the 777-9, being the larger of the two.

The Boeing 777X emerges as the larger sibling within the Boeing family, representing a significant leap forward in both size and efficiency. Comprising two variants, the 777-8 and the 777-9, the latter takes the crown as the larger of the two. With its expansive fuselage and impressive wingspan, the 777X is tailored for long-range journeys and boasts a substantial passenger capacity.

On the other hand, the Boeing 787, affectionately known as the Dreamliner, occupies a niche in the market as a smaller yet formidable aircraft designed for medium to long-range flights. Its distinguishing feature lies in its composite fuselage, a technological marvel that renders it lighter and more fuel-efficient compared to conventional aluminum counterparts. The Boeing 777X is larger than the Boeing 787 aircraft.

When it comes to passenger capacity, the 777-9 reigns supreme, typically accommodating a sizeable contingent of 400-425 passengers in its standard configuration. In contrast, the 787, with its more modest dimensions, typically carries between 240-290 passengers, depending on the variant and layout.

One of the remarkable innovations introduced with the 777X is its folding wingtips, a feature designed to address the logistical challenges of accommodating such a large aircraft in conventional airport gates. These folding wingtips enable the 777X to retract its wings, allowing it to fit into gates designed for smaller aircraft while still reaping the benefits of an extended wingspan during flight, thereby enhancing fuel efficiency and operational flexibility

China Secures Production Certificate for Mass Production of Pilotless eVTOL Aircraft

EHang

The first passenger-carrying pilotless electric vertical takeoff and landing (eVTOL) aircraft in the world, the EH216-S, has received the Production Certificate for its eVTOL aircraft from the Civil Aviation Administration of China (CAAC).

This is a significant milestone for EHang Holdings Limited, the leading UAM technology platform company in the world. This outstanding accomplishment is another big step towards mass manufacturing for the eVTOL aircraft and the ensuing commercial operations, building on the ground-breaking acquisition of the Type Certificate and the Standard Airworthiness Certificate for the EH216-S.

The PC is a crucial certificate that the aircraft maker receives from the CAAC, the country’s aviation authority. By obtaining this certificate, EHang has demonstrated that it has set up a quality management system for mass production that satisfies the airworthiness regulation standards set forth by the CAAC, and the company has been given permission to continue producing mass quantities.

It is also a strong guarantee of the calibre of the goods made by EHang. Raw materials, supplier management, manufacturing organisation, production quality control, aircraft pre-delivery test, after-sales repair and maintenance, etc. are all included in the mass production quality management system for the EH216-S.

To ensure that every aircraft and its components that roll off the production line strictly adhere to the approved type design and safety requirements, the system sets clear guidelines and documentation for every step in the production procedure. This ensures comprehensive traceability and safety control.
