By halting production, Boeing has admitted they cannot fix the MAX and satisfy the various regulators. The only option now is to drop MCAS altogether and certify it without augmentation of any kind. That should have been the aim a year ago, in fact five years ago.Jump to post
A useful rail analogy to building the (1960s) 737 hull now, would be the British Rail MK1 slam-door rolling stock. The rail coaches crumpled in much the same way in a survivable collision. The frame would often crush the fragile passenger compartments above. They were banned 20+ years ago after seve...Jump to post
Some useful background on the virus from BBC News.
What is this virus?
How severe are the symptoms?
How easily does it spread between people?
Governments are perhaps kidding themselves (and us) that this virus can be contained by simply reducing or cutting out a few flights. China has a population of 1.4 billion people at home and abroad. Those that want or need to travel will simply take an alternate route to/from an airport unaffected s...Jump to post
Meanwhile in the UK, the passengers flown in from Wuhan were put on a normal coach and driven half way across the country. The drivers safety ruled not that important?

Was the Tri-Jet era of engine technology also a factor? They were a lot less reliable than the current 77W/A330 generation, except for the current 787/RR debacle.Jump to post
What could possibly be the catastrophic failure caused by the wingtips folding up in flight? Would they cause a loss of control by somehow disrupting the airflow? I can't imagine there's enough lift generated by the wingtips for that to be the issue. The effect of one wingtip folding would be far w...Jump to post
This has probably been covered earlier, but Boeing has said a software patch is the cure for what brought down those airliners, but wasn’t relying on a single AOA sensor a contributing factor as well? What are they going to do about that? MCAS used one sensor at a time. It changed from left to righ...Jump to post
Are these RR 787 issues related to ones assembled in the UK or abroad? Bring it back in-house perhaps if that is the problem.Jump to post
How hard can it be for Boeing to build and certify a fully-protected FBW 737-8/9/10? They have virtually everything they need in stock (787). It could even be called a 737-FBW with deliveries starting around 2023/24 and could be built in tandem with the MAX. Get the MAX flying again sometime this ye...Jump to post

Captain: My impression of a 737-MAXJump to post
Isn't it ironic that when in service with BA and others, this is exactly what the 779 will be doing at LHR for the next ten years.
Winds still gusting at 29 knots
The webcam at Paine Field is working though, with ATC.

Apparently it rains 300 days a year in Seattle
Here is a link to FlightRadar24 at Paine Field, Everett.
The first 777-X should appear in the next hour or so when it powers up. It's 8am there.
Some useful background to today's first flight from the Seattle Times. Lifted by unique wings and massive engines, Boeing 777X scheduled to finally take flight Friday morning. https://www.seattletimes.com/business/boeing-aerospace/lifted-on-massive-wings-boeing-777x-scheduled-to-finally-take-flight-...Jump to post
Even Airbus must be thinking wtf. Can we help Boeing in any way? Perhaps converting Spirit and Renton to A321NEO may be not that unlikely now.Jump to post
I said in March last year, Boeing should have a plan B, and come up with a MAX conversion back to NG. The airlines just want new builds. That is now looking more and more likely for the 900 built frames. Salvage what they can and scrap the rest. Keep the engines for a new FBW model. The MAX will nev...Jump to post
With the issues that the MAX is having, and future big twins getting ever larger fans. Is it not possible to ditch the pylon altogether, and cut-away the wing and make these huge engines an integral part of the wing itself? Possibly with the exhaust split above and below the surface. A common engine...Jump to post
Another idea perhaps is to provide Flightradar24 (Gold) to all 'military' units, who are stupid enough to shoot at an airliner, lit up like a Christmas tree flying out of an international airport. That includes the Americans. Nobody would equip their missiles with an item identifying itself as a ci...Jump to post
A regional airline is never going to make money all year round on these routes. It should be a requirement of the national carrier (BA), to serve the regions properly. Not just the major cities, leaving the scraps for one failing airline after another. BA gets all the advantages of being a major at ...Jump to post
Both MH17 and this latest event occurred in countries with no previous history of having shot down an airliner. No risk assessment would have flagged either in advance. However, there is now a good chance that both countries could have a future event, so should be avoided, along with Iraq and Syria....Jump to post
Plan B, back in March last year should have been; Come up with an A320 type long landing gear, and re-position the engines back under the wing. It would likely take much the same time to certify. MCAS would not be needed and it would behave in a normal way in turns. Ironically, the 787 also has some...Jump to post

The problem with a fire causing problems for the aircraft, is that such a fire would never spread so quickly to result in a situation where the pilot doesn't mayday for help. 1. Aviate 2. Navigate 3.

This mess goes back much further than 2011. The 737 should have been replaced with a new model after the first A320-200 came out. The 737 nose and fuselage is basically 707/727 vintage from another era. Would it still be acceptable to be building the 707 or 727 in 2020. It would not. Why is it any d...Jump to post
Is it not possible to add a fuel tank in part of the longer cargo hold to extend the legs? Suitably encased and self contained for safety.
These longer length frames do seem to lose about 20% range. Why can’t the extra length be used to carry more fuel, so the range stays roughly the same?
Rather than try to tunnel and widen (again) the active M25 next to Heathrow, during the 3rd runway expansion, it should be done properly this time. If you look on Google Earth, the M25 curves in towards Heathrow, then out again. This section of the orbital motorway badly needs a bypass in a new tunn...Jump to post
Heathrow Airport has said its project to build a third runway, has been delayed by "at least 12 months" after the aviation regulator rejected its spending plans. The Civil Aviation Authority (CAA) has refused Heathrow's request to lift spending from £650m to £2.4bn before it even gets plan...Jump to post
Should Boeing or Airbus speak to airlines at all? Both have followed their advice in the past and got it completely wrong. Think back to the early A350 (pre XWB), A380, A318, 767-400, 737-700/900, the 777-8/9 and the MAX. The data is already out there and they could simply use real-world flight sche...Jump to post
This whole 737 MAX fiasco is the culmination of aviation generally, and design and technology in particular going backwards since 1969 (747 & Concorde). Except possibly the 77W. From seats that are far too narrow, crushed together while humans get ever bigger, to window blinds that no longer ope...Jump to post
I think that MCAS should have tripple input redundancy, it has to work during all flights . (emphasis added) I think this is the problem. While the MCAS update would probably have prevented the crashes had it been in place, it does nothing about, and in fact increases the probability of, false nega...Jump to post
If in March, Boeing decided to put 787 style FBW systems into a new MAX frame they would be half-way through to certification by now.Jump to post
As I've said for a while they may be better off to ditch MCAS assuming the MAX stalls somewhat normally and implement the mandatory US stall training. Someone mentioned it looked like they were doing stall tests this past weekend - they may be checking to see if this is a feasible path. The negativ...Jump to post
I chat with and listen to the actual airline pilots in this forum who have actually logged hours in the MAX or 737 that everyone seems to ignore. I believe the biggest reason other than planes and safety systems growing more reliable/redundant was the advent of crew CRM - which seems to have been l...Jump to post
