United just ordered Airbus' newest jet to replace 50 ageing Boeing 757s, while Boeing struggles to develop an alternative
United Airlines signed an order for 50 Airbus A321XLR jets on Tuesday, to replace its ageing Boeing 757 fleet.The order was confirmed by United Chief Commercial Officer Andrew Nocella Tuesday evening.
Two Boeing 737 Max crashes killed 346 people and grounded the jet, which experienced software problems. A Lion Air flight crashed into the Java Sea five months earlier. The two accidents killed a total of 346 passengers and More: Boeing says 737 Max software is fixed , now it 's up to the FAA.
Because the 737 Max had been outfitted with larger new engines that could cause its nose to pitch dangerously skyward, Boeing had added a maneuvering The autopilot then switched itself off and handed control of the plane over to the pilots , as it was designed to do under such circumstances.
- Boeing is promising three key fixes to a system blamed for the fatal crashes of its 737 Max jet, according to a leaked presentation made public by CBS News.
- It deals with changes to the Manoeuvring Characteristics Augmentation System (MCAS), which was a factor in the two crashes which led to the jet's worldwide ban from service.
- MCAS was designed to automatically push the plane's nose down to keep the jet stable in the air. But it misfired, seemingly based on faulty data from a sensor, forcing the plane into an unstoppable dive.
- In the first of the two crashes, MCAS forced the plane's nose down more than 20 times, bringing about a fatal dive which the pilots tried - but failed - to override.
- Boeing will now require two sensors to agree in order to activate MCAS, the presentation said. They will also include a manual override and prevent it from activating over and over.
is promising three fixes for the faulty autopilot system widely attributed as a cause of two deadly crashes by the 737 Max plane, Sunday.
Jetstar considers January flight cancellations to deal with pilot strike
Jetstar is preparing to major flight schedule changes through January in anticipation of pilot strikes continuing into the new year , as it braces for pilots to walk off the job this weekend.Customers remain in the dark about whether their flights will be cancelled or significantly delayed during pilots' four-hour work stoppages this Saturday and Sunday, with the Qantas owned budget carrier still finalising how it will operate through the strike. require(["inlineoutstreamAd", "c.

The plane builder wants pilots to brush up on what to do if a faulty sensor sends a 737 MAX into a dive . U.S. investigators examine recovered parts of the Lion Air jet that crashed into the sea at Tanjung Priok Port in Jakarta, Indonesia. Divers have recovered the flight data recorder from the
The manufacturer told stakeholders in Seattle last week it will introduce changes to the jets Manoeuvring Characteristics Augmentation System (MCAS), CBS News reported, citing documents from a presentation by the company.
The pilots in both crashes had struggled with MCAS, which was designed to automatically push the plane's nose down to stabilise the jet.

The software had relied on data from one of the plane's two "angle-of-attack" (AOA) sensors, which monitored the plane's position in the sky.
Both pilotsby angling the plane back up dozens of times, but MCAS kept reactivating - which ultimately .
Jetstar considers January flight cancellations to deal with pilot strike
Jetstar is preparing to major flight schedule changes through January in anticipation of pilot strikes continuing into the new year , as it braces for pilots to walk off the job this weekend. The brewing industrial dispute comes as the Qantas-owned budget carrier was hit by lengthy delays and cancellations on Tuesday due to an IT outage that affected its check-in counters at multiple airports across the country.
The beleaguered Boeing 737 MAX is now facing another headwind. This time, there are safety concerns regarding the autopilot . Here is the list, as reported by Bloomberg , of issues Boeing needs to fix with the 737 MAX : The potential difficulty pilots have in turning the jet’s manual trim wheel.
A year before the plane was finished, Boeing made the system more aggressive and riskier. In both doomed flights, pilots struggled as a single damaged sensor sent the planes into irrecoverable nose - dives within Boeing wanted to limit changes to the Max , from previous versions of the 737 .
Boeing said it has addressed these problems with updated software, CBS News reported. Here are the changes they plan to make, according to the news network:
- MCAS will now rely on readings from two AOA sensors as opposed to just one in the original system. The new software will only activate if both sensors agree that the plane's nose is too high. Boeing had announced this update .
- Pilots will be able to deactivate the system.
- When they do so, MCAS will not automatically reactivate. The original system had automatically reactivated multiple times.
Boeing also told attendees that it had flown 1,850 flight hours with the software updates, and spent more than 100,000 employee hours in engineering and test-developing the new issues, CBS News reported.
Multiple Boeing employees have spoken of the company's internal pressures to.
Inside the closed-door meeting where Boeing tried to reassure 737 Max stakeholders as the airlines and passengers get ready to fly the plane again
Boeing held a meeting last week for pilots, flight attendants, union and airline officials, and analysts, hoping to reassure them about the 737 Max. Business Insider spoke with attendees who described the meeting as "transparent," "humbling," and productive. The head of American Airlines' flight attendants' union, who previously said she and her members would refuse to work on the plane if it was not safe, said she felt Boeing was making progress ensuring that "this plane is not only safe, but that it gets in the air correctly.
Boeing dismissed concerns about a powerful new anti-stall system on the 737 Max for months, insisting The pilots had a short window to react before going into an irrecoverable nose dive . The system, according to the investigators’ findings, appears to have forced the nose of the plane down

Boeing has not yet responded to Business Insider's request for comment on the reported changes.
The company's presentation last week was meant to reassure aeroplane analysts, airlines, pilots, and flight attendants, CBS News reported. Regulators around the world have grounded their 737 Max jets, and pilots and flight staff haveof flying them again.
The US Federal Aviation Administration (FAA) had also come under pressure for vouching for the 737 Max's safety before the two crashes. The agency now wants to.
Internal messages exchanged by Boeing employees in 2016, which were released in October, also suggested that they had.
The 737 Max is expected to return to service in March 2020, though Boeing is.
