Ethiopian Airlines questions Boeing's 'aggressive' software - Software

Boeing and the Federal Aviation Administration, which must approve the software fix and new training, are under USA and global scrutiny since the MAX suffered a second deadly crash involving Ethiopian Airlines in Addis Ababa on March 10, which led to a worldwide grounding of the fleet.

Schumer's demands come two weeks after an American-made Boeing 737 MAX 8 crashed in Ethiopia, killing all 157 people on board.

A U.S. official briefed on the matter said the Federal Aviation Administration (FAA) has not yet signed off on the software upgrade and training but the goal is to review them in coming weeks and approve them by April.

The company is tweaking the system created to prevent an aerodynamic stall if sensors detect that the plane's nose is pointed too high.

The US aerospace company did not respond to requests for explanation as to why the safety options were not standard equipment.

The FAA had given until April for Boeing to make the necessary changes to the critical anti-stall system, and on March 15 two anonymous industry sources told AFP the upgrade would be ready in about 10 days. "You're trying to figure it out at the same time you're trying to fly an airplane, which is hard", Hansman observed, cited by the Star Advertiser.

On Sunday, the airline said in a statement that the cancellations would continue through April 24, resulting in 90 flights grounded every day.

But he added, "over time obviously we want to reduce that balance sheet and not have these massive amounts of debt". Asked about whether a rate cut is needed, he said "I'm not sure about that - I'd have to take a closer look at it".

"Right now we're in wait-and-see mode to see what Boeing comes up with", said Captain Jason Goldberg, spokesman for the APA, part of a delegation of airline safety experts and pilots set to test the upgrade.

In 2014, PTGI ordered 50 737 MAX 8 aircraft, with one having been delivered already.

The 3 U.S. airlines that own Boeing Co's 737 MAX are meeting the United States manufacturer this weekend to review a software upgrade for the jet that has suffered 2 fatal crashes in 5 months, officials from the airlines told Reuters.

But the FAA is not expected to allow the dozens of 737 MAX planes it grounded back into the air until it learns more about the causes of the Ethiopian Air crash, the source said. "Ethiopian Airlines believes in Boeing".

At the gathering, pilots from the three American carriers, plus two smaller non-US airlines, ran simulated flights created to mimic the situation that brought down the Lion Air flight in Indonesia previous year, using the current and updated software, according to the person briefed on the session.

"We have been engaging with all 737 MAX operators and we are continuing to schedule meetings to share information about our plans for supporting the 737 MAX fleet", the Boeing spokeswoman said, declining to confirm the timeline for the changes. It also included some self-guided instruction, the official added.
