Isn't it a bit overreacting of all parties involved by immediately (temporarily) grounding an entire fleet of planes (the 777's with this type of engine) after an engine failure? The plane landed safely and everybody walked off the plane alive. Yes, it is a serious incident. Yes, it needs to be inv...Jump to post

Days before Christmas it was becoming apparent that Delta did not have enough pilots to cover their Christmas schedule. @xJonNYC Dec 20 A little more on this; someone has reviewed the 320, 757 and 767 lists of available DL pilots/FO's for the peak Christmas period and it sure seems like DL is in for...Jump to post
Do we know if that is 3 hours hands on per pilot the sim training? Likewise do we know the split in duration between any 737 sim and a MAX specific sim? As far as I'm aware the training can also be done on a NG sim and wil last for 2 hours. But I presume the latest info will be in black-and-white o...Jump to post
I think it is important to note that the 767 and 330 accindents have a thing in common: Both happened because the pilots actively did something. Doing nothing would have saved both. Doing nothing on the MAX with active MCAS would have killed the PAX even faster. This is not strictly accurate in reg...Jump to post
We both were given unreliable airspeed, and runaway stabilizer scenarios. These were done as "first look" items, meaning we didn't brief them first, and although we knew we would be getting an abnormal, we didn't know what it would be, or when it would happen, before the event started. Wa...Jump to post
That timeline on page 100 is really something.

My understanding is that Boeing's blame positioning is a legal strategy to not cede any ground for the incoming lawsuits. They know what they screwed up.
(Whether they have taken the correct actions to fix their culture, remains to be seen...)
Wouldn't there be a need for some sort of minimal *explicit* state recognition or diplomatic relations (not just the behind-closed-doors stuff that happens right now) between Israel and the UAE before regular non-stop passenger flights can happen ?

The 777X engines are actually further out on the wing than the 777 "classic" due to their size. Would this have any implications on stability and handling characteristics? :?: Well, yes, that's why they do a robust flight test program.

I don't see how the ET302 final report will change anything substantial to the already existing NTSB report and JATR review. ET302 situation points to even broader and more fundamental issues with the entire 737 line in regards inability to manually adjust trim once it the stabilizer has reached a ...Jump to post
Unless I missed it (entirely possible), I also saw nothing that said that the force at trim extremes would require more force on the manual trim wheel than could be managed by the pilots. It doesn't appear to be mentioned in this report, but it may show up in the ET findings. It was certainly a kno...Jump to post
New MCAS test flight: http://twitter.com/AirlineFlyer/status/ ... 7560499203
I guess the test pilots know exactly what they’re doing (and have pre-briefed procedures if severely out of trim like rock-and-roll), but I still wouldn’t like to be on a plane futzing with MCAS activation at FL100...
Doesn't STS also sometimes command nose-down trim? Hence simply training to always stop "uncommanded" nose-down trim is not helpful. This is part of the pilot confusion involved in at least the Lion Air crash. And the source of the JT43 log book entry of something like "STS also runni...Jump to post
If the passenger had paid attention during the safety briefing and read the card they should have no problem opening a door and popping the slide. Plus they have the luxury of time because it's not a true emergency.Jump to post
There are no pilot actions or procedures during flight which require knowledge of angle of attack. So, yeah, we did all we were required to do, and we weren't required to provide a visual clue that the AoA sensors were providing grossly different values even while the aircraft was taxiing. AoA disp...Jump to post
For example, we know that having correctly trained people and executing the correct set of processes saved the exact same LionAir 737-Max 8 mere hours before it crashed.

Yes, but do you really believe that the knowledge and training Boeing provided was sufficient? And the implementation - seems that it needs a fix or two, right? We have to use our discernment to view reality. Of course, the training and implementation of MCAS (and certification) were woefully insuf...Jump to post
Yeah, I too fail to understand the logic of this so called fix. I mean, MCAS was deemed critical enough to the safety of the plane that it was designed and implemented in the first place. But now the fix basically self-disables the system every time there is AoA disagreement, or the pilot counters ...Jump to post
It was a trim runaway. The procedure for trim runaway would have prevented these accidents unless there is something they are not telling us.

Cost-saving printing decisions like this are sure to cause consternation for some time into the future:
I was thinking Marc Garneau told AC, WS and WG behind the scenes that they have 24 hours to arrange their fleets as they will ground the MAX today.

Same thing can happen to a AA, SW and UA max. Please be precise with what you mean by "same thing". PK-LQP (JT610) would not have been considered airworthy in the US. That closes that hole in the cheese. Can you tell me exactly what happened on ET302 to assert the "same thing" c...Jump to post

The retraction of the flaps is mainly related to the airspeed. The last data recorded by FR24 shows a ground speed in excess of 380 kts (and it was still a head wind component, since it was still flying in the same heading as it had taken off). Even considering the 8500 ft altitude, the flaps must ...Jump to post
I was thinking that as I was typing :lol: - wouldn't the aircraft have to be trimmed the same way regardless though? Otherwise you'd disable AP and MCAS would suddenly start playing with the trim?

From what I recall, MCAS is capable of commanding extreme trim inputs VERY rapidly. If you're on autopilot climbing out, reaching for a coffee or something, looking at a chart, changing a radio frequency, etc, and that thing slams full trim on you, it's tough to know how you'd react and if you woul...Jump to post

here is an article from the Seattle Times, a newspaper one hardly can call unfriendly to Boeing.

In our discussion, many times people refer to 'runaway trim'. One issue is that our understanding of what 'runaway trim' includes the knowledge of what happened on this flight. Indeed, the broader aviation community may have a new standard and viewpoint for 'runaway trim' based on this incident. It ...Jump to post
