807 Hydrogen-Electric eVTOL

The Joby hydrogen-electric eVTOL 523-mile flight, severe weather and the Southwest Dutch Roll, the danger of getting too close to an operating jet engine, excessive heat impacts on aviation, exploding soda cans that injure flight attendants, and turbulence and hot tea water burns.

Joby Aviation completes a 523-mile flight in an eVTOL powered by hydrogen-electric tech

Joby Aviation, Inc. announced it has successfully flown a liquid hydrogen-electric eVTOL  demonstrator 523 miles over California. The aircraft was based on a Joby pre-production prototype battery-electric aircraft fitted with a liquid hydrogen fuel tank and fuel cell system.

The liquid hydrogen fuel tank was designed and built by Joby. It stores up to 40 kilograms of liquid hydrogen which feeds the fuel cell system that produces electricity, water, and heat. The electricity powers six electric motors on the Joby aircraft. Batteries provide additional power primarily during take-off and landing. Joby plans to start commercial operations as soon as 2025 with its battery-electric air taxi.

Airbus to freeze hiring as it battles cut-price Chinese rival

In the face of competition from COMAC and a stronger Boeing, Airbus wants to cut costs. The company has a 6-year backlog of A320 family aircraft and is struggling to get production to the rate they desire. Aircraft owners who need narrowbody aircraft sooner are likely to look at Boeing and COMAC. So Airbus is seeking to focus its activity on an “improvement program,” although it may be years before the C919 is certified by Western regulators.

For years, COMAC, the Commercial Aircraft Corporation of China, has worked to establish a viable Chinese commercial airframer. They started with the ARJ21 regional jet and then proceeded to develop the C919 narrowbody in the B737/A320 class. Lately, they’ve been working on a C929 widebody jetliner.

A Southwest jet that did a ‘Dutch roll’ was parked outside during a severe storm

Investigators looking at the Southwest Airlines Boeing 737 Max that experienced a Dutch roll say the plane had been parked outside during thunderstorms with wind gusts of up to 84 mph. After some routine maintenance, the pilots experienced “odd movements of the rudder pedals.” The NTSB hasn’t determined when the observed tail damage occurred.

The speculation is that the tail damage occurred during the storm when the rudder slammed back and forth in the wind. Safety consultant John Cox, a former airline pilot, said “I do not see this as a Max issue. I do not see this right now as a 737 issue. I see this as a one-off.”

Airport Ground Worker Killed After Getting Sucked Into Engine of Boeing 737 When They Stepped Into the ‘Danger Zone’

The accident happened in Iran during routine maintenance when the engines were powered for a test run. The worker was trying to retrieve a tool left near the engine.

As extreme heat bakes the West, emergency helicopters struggle to fly

Medical helicopter flights have been canceled in some areas due to high temperatures. Air temperature and tarmac temperature can be factors. Also, a confined area can require more engine power to land, which is affected by high temperatures.

Amid Oppressive Heat, Broiling Airplane Cabins Add to Travelers’ Woes

Unusually hot weather is causing cabin air conditioning systems to struggle to keep up. The Department of Transportation is studying whether to set minimum standards for cabin temperatures.

Southwest Airlines Flight Attendants Are Being Injured By ‘Exploding’ Coca-Cola Cans as Summer Heats Soar

The Southwest Airlines drink restocking process is different than the one used by other airlines. Most airlines use chilled drinks carts that deliver the cans cool. But Southwest delivers the cans directly, which might be causing the problem. Southwest is investigating.

Passenger sues JetBlue for $1.5M claiming hot water scalded her, left ‘disfiguring burns’

The passenger was flying JetBlue flight 2237 from Orlando to Hartford, Connecticut. During the beverage service, some turbulence occurred and hot tea water spilled on the woman. She is suing JetBlue over alleged “disfiguring burns” and claiming JetBlue was “careless” and did not provide her with “reasonably safe traveling conditions.” The complaint alleges second and third-degree burns to the chest, legs, right arm, and backside.

Seattle-Tacoma plane thief ‘had full airport credentials’

A Horizon Air Bombardier Q400 turboprop was stolen by an airline employee at Seattle’s SeaTac International airport and made an unauthorized takeoff. Horizon is a subsidiary of Alaska Air Group. During a 75-minute flight, the plane made some aerobatic maneuvers, was chased by two Air National Guard F-15Cs, and crashed on Ketron Island in Puget Sound.

Meet the UK’s New, Very British Fighter Jet

A full-scale model of the UK’s new Tempest fighter jet was displayed at Farnborough this year. It’s being called a 6th generation fighter with two engines and twin vertical stabilizers, not unlike the F-22. The UK’s Ministry of Defense plans on spending $2.6 billion to develop the plane through 2025. Then a decision will be made to proceed with a 2035 rollout.

Stale Cockpit Air May Be Dulling Your Airline Pilot’s Performance

A new Harvard University study published in the Journal of Exposure Science & Environmental Epidemiology has found that carbon dioxide concentrations in the cockpit can affect pilot performance. Current regulations don’t address fresh air in airline flight decks and the impact of carbon dioxide on safety. The article is Airplane pilot flight performance on 21 maneuvers in a flight simulator under varying carbon dioxide concentrations.

Women airline pilots: a tiny percentage, and only growing slowly

CAPA, the Centre for Aviation, says, “Data for the US and the UK indicate that just over 4% of airline pilots are women.”

  • 7.0% of all US FAA pilot airline pilot certificates are held by women, while 4.4% of US airline pilots and 4.3% of UK airline pilots are women.
  • Women pilots’ share is growing but by less than 1ppt over a decade.
  • Among global airlines surveyed by the International Society of Women Airline Pilots, the US big three have the highest number of women pilots.
  • IndiGo has the highest percentage of women pilots, with 13.9%.

Suing the Airlines for Better Bathroom Access

The 1986 Air Carrier Access Act prohibits discrimination based on disability in air travel. New twin-aisle planes are required to have a wheelchair accessible lavatory. Single-aisle planes have no such requirement. The Paralyzed Veterans of America organization has filed a lawsuit against the United States Department of Transportation.

From the press release: Paralyzed Veterans of America Sues Department of Transportation For Unlawful Delay of Rule Intended to Make Airline Restrooms Accessible for Travelers With Disabilities:

“…on behalf of Paralyzed Veterans of America, Democracy Forward challenged the U.S. Department of Transportation (DOT) for its unjustified and unlawful delay in issuing rules intended to make airplane restrooms accessible for travelers with disabilities.”
