Twinjet, s-duct, winglets, contra-rotating propellers: the aviation industry has developed numerous configurations over the last five decades that have enabled aircraft to fly higher, faster and longer. Now, Airbus engineers are unveiling a new configuration as part of the ZEROe programme that could enable a passenger aircraft to fly farther than ever without emissions.
The innovative approach consists of six, eight-bladed “pods” mounted beneath the aircraft wing. While the “podded” engine is not a new concept in aviation, these “pods” are not designed to be driven by any ordinary propulsion system: hydrogen fuel cells are among the key components.
“The ‘pod’ configuration is essentially a distributed fuel cell propulsion system that delivers thrust to the aircraft via six propulsors arranged along the wing,” explains Matthieu Thomas, ZEROe Aircraft Lead Architect. “Hydrogen fuel cells have very different design considerations, so we knew we had to come up with a unique approach.”
Indeed, hydrogen fuel cell technology has yet to be scaled up to a passenger-size large commercial aircraft. Smaller experimental hydrogen aircraft, comprising up to 20 seats, can rely on a traditional fixed-wing configuration with two propellers. But more passenger capacity and longer range require another solution. This is why Airbus is studying a variety of configurations, including “pods,” to determine which option has the potential to scale up to larger aircraft.
WASHINGTON (Reuters) – Boeing Co <BA> said on Friday it is addressing a new software issue discovered in Iowa last weekend during a technical review of the proposed update to the grounded Boeing 737 MAX, a development that could further delay the plane’s return to service.
“We are making necessary updates,” Boeing said in a statement. Officials at the planemaker said the issue relates to a software power-up monitoring function that verifies some system monitors are operating correctly.
One of the monitors was not being initiated correctly, officials said. The monitor check is prompted by a software command at airplane or system power up, and will set the appropriate indication if maintenance is required, company officials added.
The Federal Aviation Administration (FAA) did not immediately comment. ABC News reported the issue early Friday.
Boeing is halting production of the 737 MAX this month following the grounding in March of its best-selling plane after two fatal crashes in five months killed 346 people.
U.S. regulators are waiting for an update from Boeing on how they will resolve the issue. A U.S. official briefed on the matter said Friday the FAA is now unlikely to approve the plane’s return until March but it could take until April.
This week, American Airlines Group Inc <AAL> and Southwest Airlines Co <LUV> both said they would extend cancellations of MAX flights until early June.
Also this month, the FAA and Boeing said they were reviewing a wiring issue that could potentially cause a short circuit on the grounded 737 MAX. Officials said the review is looking at whether two bundles of wiring are too close together, which could lead to a short circuit and potentially result in a crash if pilots did not respond appropriately.
U.S. and European aviation safety regulators met with Boeing in an effort to complete a 737 MAX software documentation audit that was begun in November. Documentation requirements are central to certification for increasingly complex aircraft software, and can become a source of delays.

São José dos Campos, Brazil, December 30th, 2019 – Air Kiribati, the flag carrier of the Republic of Kiribati, received today its first E190-E2 jet. Embraer announced the contract with the Government of Kiribati, in partnership with its national airline, Air Kiribati, in December 2018. The airline ordered two E190-E2s and has purchase rights for two more.
“Aviation is critical for any island nation and Kiribati is no exception. Our Government has made the conscious decision to take into our hands the opportunity to unlock economic prosperity for our people and our nation through the purchase of these two aircraft,” said Hon. Willie Tokataake, Minister for Information, Communication, Transport and Tourism Development of the Kiribati Government. “The arrival of our first jet today is the culmination of three years of vision, strategic thought, government focus, research, evaluation, hard work, commitment, partnership and a good measure of problem solving.”
Air Kiribati is the launch operator for the E190-E2 in Asia Pacific. The aircraft will be configured in a dual class layout seating 92 passengers in total, with 12 seats in business class and 80 seats in economy class. Located in the central Pacific, Air Kiribati can now fly longer domestic and international routes than it currently does with its turboprop fleet.
“This is first E190-E2 delivered in the Pacific region,” said Cesar Pereira, Asia Pacific Vice President, Embraer Commercial Aviation. “We’re are honored that Air Kiribati selected the E190-E2 as the best fit for the airline’s challenging flying environment. The E190-E2 has cutting-edge technology and is the most fuel efficient and environmentally-friendly single aisle jet in the world. These attributes are extremely important for Kiribati.”
With a maximum range of up to 2,850 nautical miles, the E190-E2 can serve destinations throughout the vast expanse of Kiribati, including nonstop from Tarawa to Kiritimati (Christmas) Island, one of the most challenging routes in the Pacific. The current domestic flight from Tarawa to Kiritimati requires an international stopover in Fiji.
Spanning four time zones and comprised of more than 30 islands, Kiribati is the only country in the world to be in all four hemispheres. Embraer has been present in the Pacific since the first Bandeirante was delivered to a customer in Australia in 1978. The company continues to support operators across Oceania more than 40 years later.
The E190-E2 is the first of three new aircraft types in the E-Jets E2 family, developed to succeed the first-generation E-Jets. Compared to the first-generation E190, the E190-E2 burns 17.3% less fuel and nearly 10% less than its direct competitor. This makes it the most efficient single-aisle aircraft on the market. The E190-E2 generates significant savings for airlines in terms of maintenance costs. It has the longest maintenance intervals – 10,000 flight hours for basic checks and no calendar limit in typical E-Jets utilization. This means an additional 15 days of aircraft utilization over a period of ten years.
The E2 cockpit features advanced Honeywell Primus Epic 2 integrated avionics. Combined with closed-loop fly-by-wire controls, the systems work together to improve aircraft performance, decrease pilot workload and enhance flight safety. From a passenger perspective, the E2 cabin features a comfortable two-by-two layout. The absence of a middle seat enables passengers to have an enjoyable flight experience with more legroom and additional luggage storage space.
Embraer is the world’s leading manufacturer of commercial aircraft up to 150 seats with more than 100 customers across the world. For the E-Jets program alone, Embraer has logged more than 1,800 orders and 1,500 aircraft have been delivered. Today, E-Jets are flying in the fleets of 80 customers from 50 countries. The versatile 70 to 150-seat family is flying with low-cost airlines as well as with regional and mainline network carriers.

ARLINGTON, Va., March. 20, 2019 – With a three-year
contract award for 78 F/A-18 Block III Super Hornets, Boeing [NYSE: BA]
will play a vital role in the U.S. Navy’s fleet modernization efforts.
The Block III configuration adds capability upgrades that include enhanced network capability, longer range, reduced radar signature, an advanced cockpit system and an enhanced communication system. Boeing will begin converting existing Block II Super Hornets to Block III early in the next decade. The fighter’s life also will be extended from 6,000 hours to 10,000 hours.
This new multi-year contract benefits the U.S. Navy and Boeing by
allowing both to schedule future production and Navy officials estimate
this multi-year model saves a minimum of $395 million on this contract
valued at approximately $4 billion.
“This multiyear contract will provide significant savings for taxpayers and the U.S. Navy while providing the capacity it needs to help improve readiness,” said Dan Gillian, vice president of F/A-18 and EA-18G programs. “A multiyear contract helps the F/A-18 team seek out suppliers with a guaranteed three years of production, instead of negotiating year to year. It helps both sides with planning, and we applaud the U.S. Navy on taking the appropriate steps needed to help solve its readiness challenges.”
