Are you a pilot? Because that describes 90% of the pilot's I work with.

Did NOT need to know that.

It's legal for one pilot in the cockpit to snooze in cruise. Especially on long-haul flights with relief crews.

Trick is to not fall asleep while the other guy is haha.

Falling asleep is my superpower. I can fall asleep anywhere very quickly.

Splitting this thread off... Interesting observation by heavyfuel with the 737 MAX 8 in the news. Hoping other pilots can chime in. Been reading up on the 787 MAX 8 design, with the new fuel efficient engines stuffed way up front, fucking up CoG which necessitates a MCAS system to make sure the plane doesn't accidently stall.

Reading up on some of the pilot forums, initial data as well as historical flight data is showing some consistency between the Lion Air and Ethiopian Airline crashes where failing speed and/or AoA sensors cause the MCAS to kick in incorrectly and nose down the plane. The bad part in all this is that the MCAS isn't mentioned in pilot training which is odd.

I don’t fly the MAX but we do have a controlled rest in the cockpit rule at my airline. We’re allowed 30 mins asleep and then 10 minutes once awake before were allowed to touch the controls. Pretty industry standard.

Until Boeing ruined it, MCAS always stood for Mad Crazy Asian Style. You know, “because China” sort of stuff. Especially the Asian photography action stance.

UK have banned the Max from its airspace.

Because China took the lead. Definitely has nothing to do with a trade war. Those are easy to win.

This isn't a stall (at least what we know with Lion Air). This is the plane thinking it's a stall due to bad data, and auto recovering by forcibly going nose down. Basically, you're taking off, MCAS decides it's stalling even when it's not, and nose dives into the ground trying to recover from a non existent stall.

From a pilots perspective, plane is gaining altitude during take off, and then suddenly and inexplicably just pitches down under it's own control even with autopilot off. Pulling back on the stick doesn't disable MCAS, which is probably a pretty big design flaw right there.

Yes I gathered that. My bad for going a bit off topic in the context this thread has changed to. All the talk of stalls just made me think of what I posted.

But if it's on a checklist, why are pilots ignoring it?

Why do you keep saying they're ignoring it? As it was explained, the pilots are not ignoring the switch, but the switch now serves a secondary function which has not been made aware to the pilots. How far does a pilots due diligence go as far as checks? Should he/she be required to question every single toggle and switch as to whether it now serves multiple functions every time they get in a plane? You can't have pilots on a witch hunt every time they get in a plane.

Several countries grounding them on the idea they are "unsafe".

Absolutely the case. Its sad that airplanes have to crash before something actually gets done - tombstone engineering - and not just a Boeing thing as well.

Profits before lives is the name of the game in the industry, at a corporate-level.

We have been training a generation of engineers to beta test in released products. This is the consequence.

[ZenOps]

The bandwagon starts now. WestJet hasn't grounded yet, but they can at any time. I'd definitely take an extra day and few hundred dollar hit to fly a different plane.

Probably too early to tell if the crashes are linked to the same issues, but it's a Boeing witch hunt out there. Good to see FAA and Transport Canada not grounding the flights based on conjecture and social media concerns, but man they're going to take a beating on that decision in terms of optics.

Lots more countries banning the MAX pending investigation, including the UK. Southwest is allowing customers to re-book on alternate aircraft, American is not. Interesting to see such a knee-jerk reaction to this with no information whatsoever on what caused the latest crash, but I guess better safe than sorry in all cases like this.

Any way to capitalize on this? 50 dollar flights to Vegas on shines new max 8’s first class?

I can see the slogan now: "$50 flights to Vegas - gamble with your life!"

so, just curious. I booked my flight with Expedia to las vegas next week, and the itinerary makes no reference to the type of plane...is there any way to find out?

Go to seatguru.com and put in the flight number, date, and airline - it will tell you exactly so long as a plane has been selected, which it probably has. Usually it says on the booking/e-tickets though.

[killramos]

The max 8 is so nice... I really wouldn’t be concerned.

I guarantee a memo about MCAS has made it to WJ AND AC’s pilots by now.

[lilmira]

probably the safest plane to fly on now

[killramos]

Compared to some of the dog shit planes that make it into sky ferrying people to Mexico on the cheap?

I’ll take a brand new Boeing with a software quirk with a known fix any day.
