Embraer and Pratt & Whitney Complete 100% SAF Flight Testing of GTF-powered E195-E2 Aircraft

Embraer and Pratt & Whitney Complete 100% SAF Flight Testing of GTF-powered E195-E2 Aircraft

Fort Lauderdale, Fla., June 30, 2022 – Embraer and Pratt & Whitney have successfully tested a GTF-powered E195-E2 aircraft on 100% sustainable aviation fuel (SAF). The test, with one engine running on 100% SAF, validated that GTF engines and the E-Jets E2 family can fly on both engines with blends of up to 100% SAF without any compromise to safety or performance. The aircraft completed two days of ground tests at Fort Lauderdale International Airport, culminating in a 70-minute flight test at Vero Beach Regional Airport in Florida.

“The E2 is already the most efficient single-aisle aircraft flying today, saving up to 25% CO2 emissions compared to previous generation aircraft. This reduction in emissions can be increased up to an impressive 85% with 100% SAF. Replacement of older aircraft by new-generation products and scaling up SAF production are the two most effective actions commercial aviation can take now to achieve a significant reduction in emissions,” said Rodrigo Silva e Souza, vice president of strategy and sustainability, Embraer Commercial Aviation. “Embraer and Pratt & Whitney are leading the industry with products that are more efficient for our customers and more sustainable for our society. This test demonstrates that the E2 is ready for 100% SAF certification and operation once the industry finalizes standards.”

All Pratt & Whitney engines and Embraer aircraft are currently certified to operate with SAF blended up to 50% with standard Jet A/A1 kerosene, according to ASTM International specifications. Future specifications will enable blends of up to 100% SAF to maximize the emissions reduction potential of using fuel derived from sustainable, non-fossil-based feedstocks.

“SAF is a core part of our sustainability road map, and we continue to work with industry partners and regulators to support the development of a drop-in standard for 100% SAF,” said Graham Webb, chief sustainability officer at Pratt & Whitney. “This test proves that GTF engines can operate on any fuel, and that the E-Jets E2 family is ready for 100% SAF certification once the industry finalizes the standard for unblended SAF.”

The SAF used by Embraer and Pratt & Whitney was 100% Hydroprocessed Esters and Fatty Acids Synthetic Paraffinic Kerosine (HEFA-SPK) acquired from World Energy. HEFA-SPK is a specific type of hydrotreated renewable feedstock fuel used in aviation and is considered a leading alternative replacement for conventional jet fuel by the Commercial Aviation Alternative Fuels Initiative (CAAFI), due to the sustainability of its feedstock.

The Pratt & Whitney GTF™ engine is the only geared propulsion system delivering industry-leading sustainability benefits and world-class operating costs. The Embraer E195-E2 powered by GTF engines represents the most environmentally friendly combination of airframe and engine delivering the lowest level of noise and emissions.

B737 MAX 8 Cabin System Malfunctions: Passengers Experience Nosebleeds and Ear Pain

A Boeing 737 MAX 8 jet operated by Korean Air, bound for Taichung, Taiwan, encountered a distressing incident when its cabin pressurization system malfunctioned shortly after takeoff.

Reports from passengers described a sudden onset of problems, prompting the aircraft to promptly return to Incheon International Airport in Seoul, South Korea. As the malfunction unfolded, the aircraft was compelled to rapidly descend from its cruising altitude of over 30,000 feet to approximately 9,000 feet.

2 passengers suffered nosebleeds; 15 reported ear pain

This sudden change in altitude caused discomfort among passengers, with at least two individuals suffering from nosebleeds and 15 others experiencing ear pain and hyperventilation. Emergency protocols were swiftly activated, including the deployment of oxygen masks as the aircraft descended.

Passengers recounted harrowing moments during the incident, describing how the aircraft unexpectedly lowered altitude during meal service, leading to cries from children and widespread discomfort among travelers. Many reported sensations of ear pain, dizziness, and the disorienting effects of sudden cabin pressure changes.

Despite the chaotic situation, the cabin crew was commended for their prompt response, assisting passengers with oxygen masks and swiftly securing the cabin for landing. The pilots successfully landed the aircraft back at Incheon International Airport, ensuring the safety of all on board by 7:38 p.m. local time.

No serious injuries reported despite the alarming incident

Following the incident, Korean Air took immediate steps to mitigate disruption, arranging for a different aircraft to complete the flight to Taichung the following morning. The airline issued an apology to affected passengers and initiated an investigation into the root cause of the malfunction.

Videos shared by Taiwanese passengers captured the tense atmosphere inside the cabin during the incident, highlighting the urgency and gravity of the situation faced by those on board.

How Emirates pilots reduce fuel and emissions during operations

How Emirates pilots reduce fuel and emissions during operations

Flying smarter and minimizing fuel consumption and emissions starts in the cockpit. Emirates embarked on implementing “Green Operating Procedures” (‘Green Ops’) in 2016, adopting a multi-pronged approach to reduce on-ground and in-flight fuel use.

This initiative also provides pilots with necessary education, awareness, data analytics, and technology to manage flights efficiently.

Led by an internal cross-functional Operations Efficiency Steering Group, Emirates aims to mitigate unnecessary fuel burn and emissions while maintaining high safety standards.

In the financial year 2023-2024, ‘Green Ops’ and other initiatives helped reduce fuel burn by over 48,000 tonnes and carbon emissions by more than 151,000 tonnes. Key operational measures include:

Discretionary Extra Fuel

  • Pilots assess operational circumstances to uplift extra fuel beyond the minimum regulatory standards only when necessary, resulting in a significant reduction of discretionary extra fuel uplift.

Flight Speed Optimization

  • Pilots optimize flight speed to reduce fuel consumption while maintaining schedule integrity, as part of Emirates’ standard operating procedures.

Reduced Flap Landing

  • Pilots select flap settings that minimize aerodynamic drag, reducing fuel consumption without compromising safety.

Idle Reverse Thrust

  • Upon landing, pilots use idle reverse thrust to decelerate the aircraft, depending on runway conditions, to reduce fuel consumption.

Reduced Engine Taxi-In (RETI)

  • After landing, pilots shut down one or two engines during ground taxiing, increasing the use of RETI sevenfold since its introduction.

Optimized Flight Routings

  • Emirates uses flexible flight routes, optimizing each route for fuel efficiency and time savings since 2003.

Technology and Innovation – FlightPulse

  • Emirates introduced FlightPulse, a self-service data analytics tool developed with GE Digital Aviation Services, enhancing monitoring and collaboration for improved safety and fuel efficiency.

Center of Gravity Optimization

  • Aircraft are loaded to optimize the center of gravity, enhancing aerodynamic efficiency and saving fuel.

APU Usage

  • On the ground, Emirates reduces APU usage in favor of electrical ground power units (GPU), reducing emissions by over 30%.

Adjusted Potable Water Uplift

  • Flights upload the required amount of potable water calculated scientifically, reducing weight and ensuring fuel efficiency without compromising passenger comfort.

Through these comprehensive measures, Emirates pilots play a crucial role in reducing fuel consumption and emissions, contributing to more sustainable airline operations.

Air India Alters Elderly Couple’s US Flights Without Notice

Air India Alters Elderly Couple's US Flights Without Notice

An elderly couple’s travel plans were unexpectedly disrupted when Air India allegedly changed their tickets and destinations without prior notification, as reported by a user recounting the ordeal.

According to Dushyant Arora, the couple discovered the changes only when they attempted to check in for their flight to Newark, New Jersey, scheduled for June 19.

They were shocked to find that Air India had booked them on separate flights. The husband was re-routed to New York instead of Newark, departing on a different day than originally planned, while the wife’s itinerary remained unchanged.

The couple, unfamiliar with the changes and concerned about flying separately, decided to cancel their tickets. This decision was particularly difficult for the mother, as it would have been her first time flying abroad, and she expressed reluctance to travel alone.

The couple was not contacted by anyone from the airline to inform them of the changes. The tickets had to be cancelled by the couple. In response to the X user, Air India stated that the customer’s request for a complete refund has been fulfilled.

“Dear Sir, we apologise that this happened and assure you that we never plan to interfere with our clients’ travel arrangements. “We have conducted a complete refund in accordance with the primary customer’s request, who was booked in the PNR,” stated Air India.
