Re: New Greater Seattle Airport

"We've been looking at it from a time standpoint, not necessarily a distance standpoint," Bishop said. "If you can get from Moses Lake to Seattle within an hour, then I certainly think from an international model, that fits in those parameters." Sounds like a deal, if you can do...

Re: B737MAX Grounded Worldwide

The pilots before them did it didn't they? Bradin 's post, just after yours is terrifying. You have juste taken off and your plane doesn't seem to want to climb. You pull the yoke to go up while the opposit happens and in no time the nose goes really down. Then, more you pull up more you dive. It's...

Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

This article https://m.huffpost.com/us/entry/us_5c882682e4b0450ddae54075 has two reports of a sudden pitch down after the autopilot is engaged. This would support the notion that something more than MCAS is involved. Edited to add this direct link to the pilot asrs report. https://www.documentcloud...

Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

Boeing was (as I understand it) originally targeting this month for the change but it has apparently slipped a bit. Embedded QA is hard. Embedded QA in a highly regulated industry is infinitely harder (one of our old posters Astuteman had horror stories from back in the day as it related to softwar...

So Lion Air flight crashed 12 min after T-O and Ethiopian Airlines crashed 12 min after T-O. Bith having control issues. Does not look good for Boeing.


The Ethiopian flight crashed 6 min after T-O, but what's a 100% error among friends? :roll:

Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

I never want to see "So easy a child could fly it" in Boeing's marketing material... I’d love to see that. Not to inject too much levity into a somber discussion, but I can imagine some airlines would love to see that, too. They could dispense with their cockpit crews almost entirely, and...

Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

If the pilots were experiencing issues with airspeed during and right after departure, could they have raised the flaps earlier than normal in order to place the aircraft into an above stall speed state of flight? That’s sorta what I was thinking. Something like this could make sense given the know...

Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

I saw something that the MCAS can be turned off. Wouldn't that solve the issue? It can and it would. The problem would be if the pilots failed to diagnose the issue they were experiencing as being related to MCAS, and thus never thought of disengaging it. So if it's turned off during take off and c...

Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

For example: https://www.youtube.com/watch?v=9WOZPaO7gi0 around 60s after lift off the flaps are retracted... Sure different height etc .. Flew a UA 738 back in September and we used flaps 1 on takeoff from SEA, and the flaps were retracted around 45 seconds after takeoff Do you recall if the autop...

Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

I think something else should be considered as well. The premise is that at Flaps 1 the MCAS is always deactivated. But what if it doesn’t always deactivate it. What if that is part of the problem. As a programmer you are always faced with how things are suppose to work versus how they actually do ...

Wow. You and OEMInsider are making this thread so worth it. A.net at its best. Making following this thread worth it, despite the yes-noers trying to take the thread down... Amateur aviation geek here, but isn’t this analysis undercut by MCAS not being operational while flaps are extended? It would...

Re: Ethiopian Airlines 737MAX crashes enroute to Nairobi

I downloaded the data from the blog and I would say it is an MCAS case. See how the normal positive climb rate drops from time to time: https://flightzoomer.com/images/ET302-vspd.png If these vspd drops would be induced by MCAS, we would be able find the find 10s periods, after which MCAS would kic...

Re: N777UA- How much longer does she have?

If the prototype didn't earn a spot in Boeing's museum, why would any other? The MoF doesn't have a 757 or 767, either. As noted above, the covered "airpark" is completely full, so the only alternative would be parking it outdoors. They've already got several other aircraft in open-air, i...

Re: Youth Mission Group American Airlines Nightmare

40 kids? International destination? I guarantee I would have been there more than 2 hours prior. That's the bare minimum for individuals - as a group? Not even close. Bingo! I would consider the “two hours” to be a bad idea for anyone on an international flight from even a reasonably-busy airport, ...
