Speaking of Ryanair - how many of 737max aircraft due to delivery soon are already schedulled into their summer schedulle? Won't they have to cancel quite a lot of flights again?

Agree, but there may well be a further complication if even a small proportion of the travelling public can't or won't distinguish between the 737 Max and the thousands of others without the particular model suffix. Very difficult to predict or quantify but it's difficult to believe that there won't be some collateral damage to the 737 brand. I imagine the PR and Commercial departments of "old" model 737s will be giving this some thought and will be looking for any signs of avoidance.

At least two US flights have reported that an automated system seemed to cause their Boeing 737 MAX 8 planes to tilt down suddenly. In reports filed last year in a database compiled by NASA, the pilots said that soon after engaging the autopilot on their planes, the nose tilted down sharply. In both cases they recovered quickly after disconnecting the autopilot. Remember Boeing developed the MCAS to give the 737MAX the same handling qualities in turns as the 737NG, ie eliminate the nose-up tendency that the LEAP engines create. The aircraft should be flyable with out it, and is most definitely flyable with the electric stab trim disabled (this would have been a test case). The issue is that it will fly differently. Systems that allow two different aircraft to handle the same are quite common these days. In fact the modern FBW systems are design to do just that. The 737 is a legacy and so any systems that does this will have been built on top of other systems which may not have been designed with that function in mind. There are a number of questions that are not answered in the public domain, but should be asked

This article sounds damning, but plausible:
https://www.seattletimes.com/busines...ion-air-crash/ Other than the author's fixation with "high speed stall" when he actually just means "stall", it sounds as if he could have talked to the right people. But if it IS true it's pretty damning about the state of engineering governance in Boeing IMHO. PDR |

Being serious as Boeing will have to rework every single plane and everything will need recertifying so it could be 6-9 months. In addition nobody will be taking deliveries of them either so your production schedule is shot for 2 years. Boeing will be lucky if cost is under $2 billion because of delays, rework and compensation. Every single plane will need this and they haven't even started yet hence my timetable may be too short. Just updating a piece of software like a laptop will not bring confidence back.

Well well well, Boeing seem to be suggesting that in fact a bird strike was the most likely cause of Ethiopian Airlines and guess what, shares are on the up! 😉

In this article it isn't Boeing that's pushing the idea of a bird strike. https://www.pprune.org/rumours-news/...l#post10476671
