If you believe that we should be flying commercial civie poo poo that is so off balance that it can't be controlled by humans, sure. That's my contention here. I don't know the answer, but at this point in technology I'm pretty sure I know how I feel about it.

The point I'm trying to make is that we have been flying commercial and civilian aircraft that can be piloted largely by hand. The MAX 8 had a design consideration that made it so prone to nose up that they felt/were regulated into needing to put in software to stop that regardless of autopilot on or off because the tendency was that bad.

So now we can go into Airbus fully automated theory vs. pilot control, but where my mind goes is more like the original example of the stealth bomber, which was/is so aerodynamically unstable that no human can possibly pilot it unassisted. Are those dynamics acceptable for commercial flight? Now? Sometime in the future?

luv 2 get custom titles from a forum that goes into revolt when its told to stop using a bad word.
BA CW has gotten noticeably worse in the few months since I last flew with them. And the 787 cabin looked older and more busted than either of the 747s I flew last summer. It's like the airline is embracing Brexit austerity even before it happens.

Edit - there wasn't even wifi, which seems inexcusable for such a new airframe.

I think those dynamics are inevitable - "easy for humans to fly" is going to be largely an impediment to the next generation of continued technological innovation: increased fuel efficiency, longer range, better revenue per seat, shorter turnover times, shorter taxi distances, etc. The mistake was trying to make this jump AND ALSO not training pilots. Planes too complicated to pilot by hand are going to be universal eventually, but in order to manage such complex systems safely, more and more simulation and human training is going to be required, especially during this transition period.

The damning thing is that they tried to BOTH make this leap AND get away with not training people on the new systems.

isn't this more a problem with boeing engineering a hosed up airplane because they were way behind the eight ball than any sort of real evolution in flight controls? if they cleansheeted a next gen single aisle with fancy new engines it wouldn't require MCAS

I make friendly conversation with the store owner while browsing through their stock when I notice the shelves full of KKK memorabilia. He casually mentions that he can barely keep that stuff on the shelf because it keeps selling out. I didn't know how to respond other than "Oh, that's uh...neat" and made my way out of the store.

Not quite. It involves the airplanes being re-engined for more fuel efficient engines. But those engines had to be shifted forward which changes the center of gravity. This makes it a bit more prone to pitching upwards on sharp take offs. Which can cause a stall. The MCAS is supposed to prevent this but is prone to issues when one of the AoA sensors is out of whack. The issues seem to be pilot training and redundancy in the MCAS. There appears to be telemetry data from US airlines that similar situations happened but the pilots acted correctly to correct the situation. The basic design of the MAXs aren't bad but it looks like Boeing was far more optimistic about the amount of training needed than the reality.

Agreed. If your old airframe can't support newer, more efficient engines without some software to compensate, maybe its time to go back to the drawing board.

Almost never. I've only gotten one unasked for upgrade at a hotel that I wasn't on first name basis with the staff at. That being said, if you're at a Hilton property that would have an upgrade, don't hesitate to ask if they have an upgrade available.

I learned this at Marriott a few years back. Been Gold or Platinum Elite with them for a while but almost never got a comp upgrade until I just started asking at check in, where I'm now close to 50% successful. I don't know if it is an unwritten rule or what but they don't just hand them out automatically, whatever the program rules state.

I thought that the problem wasn't that the 737 MAX design was bad from an engineering standpoint, it's that it would have required retraining pilots, thereby defeating the entire economic purpose of the 737. The MCAS was added to "fix" this, and welp.

movax

It was bad from the day “must not require retraining / additional type certification” made it into DOORS or whatever the gently caress as a requirement.

If it’s true that MCAS isn’t fault tolerant, can command large deltas to control surfaces and a single sensor failure / erroneous input compromises it (this part really pisses me off as an engineer), the safety critical system added to offset an aerodynamic compromise that was a response to design requirements...

MCAS is in place because the 737 MAX design is bad in that the location of the engines changed the CG and the power that they output means that at low speed flaps down the nose can pitch up due to added throttle and cause a stall. that is a bad design.

More on the 737MAX ... Can you say DEREGULATION?

Here's more info on the 737MAX incidents:

To Review: Radar data has indicated that both planes jerked up and down in erratic fashion after takeoff. The captain of the Ethiopian Airlines flight reported a “flight control” problem to the air-traffic control tower. Data from the black box of the Lion Air plane showed that its pilots repeatedly pulled back on the control yoke to try to disengage the mcas and level the flight path of the plane. “The pilots fought continuously until the end of the flight,” an official from the Indonesian National Transportation Safety Committee said in November, after the plane’s black box was recovered.

And now:

It turns out that the F.A.A., with congressional approval, has “over the years delegated increasing authority to Boeing to take on more of the work of certifying the safety of its own airplanes,” the Seattle Times said. In the case of the 737 Max, which is a longer and more fuel-efficient version of previous 737s, Boeing was particularly eager to get the plane into service quickly, so it could compete with Airbus’s new A320neo. [ed comment: :capitalism:]

Early on, employees of the F.A.A. and Boeing decided how to divide up the certification work. But, partway through the process, a former F.A.A. safety engineer told the Seattle Times, “we were asked by management to re-evaluate what would be delegated. Management thought we had retained too much at the FAA.” The engineer said that “there was constant pressure to re-evaluate our initial decisions,” and “even after we had reassessed it … there was continued discussion by management about delegating even more items down to the Boeing Company.”

Even the work that was retained, such as reviewing technical documents provided by Boeing, was sometimes curtailed. “There wasn’t a complete and proper review of the documents,” the former engineer added. “Review was rushed to reach certain certification dates.”

The new revelations don’t stop there. “Federal prosecutors and Department of Transportation officials are scrutinizing the development of Boeing Co.’s 737 MAX jetliners,” the Wall Street Journal reported on Monday. “A grand jury in Washington, D.C., issued a broad subpoena dated March 11 to at least one person involved in the 737 MAX’s development, seeking related documents, including correspondence, emails and other messages,” a source told the paper.

The criminal investigation began well before the crash of the Ethiopian Airlines Flight. It’s not clear yet whether it is focussing on the mcas system, the report in the Journal said. But, that article added, “In the U.S., it is highly unusual for federal prosecutors to investigate details of regulatory approval of commercial aircraft designs, or to use a criminal probe to delve into dealings between the FAA and the largest aircraft manufacturer the agency oversees. Probes of airliner programs or alleged lapses in federal safety oversight typically are handled as civil cases, often by the DOT inspector general.”

I’m constantly getting upgrades at Marriott/SPG brand hotels as a ~~Titanium Elite~~ bonvoy member. I don’t even care for them as I’m only in them one night, but then again, maybe that’s why I’m getting them. The Sheraton Norfolk gave me the presidential suite one time - it was larger than my condo.

Although, from having worked in hotel A/V through the years, it wasn’t the most impressive presidential suite I’ve seen before - some get really insane

Yes to lovely experiences, no to Bonvoy. Marriott has just gotten lovely and unreliable since they merged.

I ditched Marriott at the beginning of the year after they billed me for someone else's stay, because someone fat fingered my rewards account number in at the hotel in error. Nevermind the fact that they shouldn't be able to charge a customer through a rewards account, but there you go. The hotel couldn't resolve the issue, call corporate. Corporate couldn't resolve the issue, call the hotel. I ended up doing a chargeback on my credit card after spending 4 hours in total calling, sitting on hold, not getting any resolution.

HIlton may not have as nice properties, but I've yet to have an issue where someone wasn't able to quickly take responsibility and get it resolved with minimal effort on my part.

Increasing the points required for rewards stays was the final straw for me, not booking Mariott unless I have to.

My company just sent out an email saying that booking through Concur is mandatory, up until recently it had been "highly encouraged."
So RIP bonus for booking through app points, you were too good for this world.
