Boeing should've designed that hole to be available for access by shorter person too, I think Boeing made questionable design choice this time. Plugging the other hole is simple, yet only lately implemented and with $2k price tag, while you can probably order that part wholesale from Chinese suppli...
Jump to postThank you for all of your feedbacks. To accommodate 95% of people based on study required 28"+ seat to seat distance, so basically the minimum limit for seat pitch based on anthropometric data is around 31", considering the thickness of slimline seat. Sub 30" will only accommodate 77%...
Jump to postI'd rather see a defined standard that's required to be displayed while purchasing, so people can easily choose between 28" and 32" as they please. Right now it takes resources like SeatGuru and a bit of airplane nerdery to really know what you're getting in to. Pitch is a poor marker, th...

My main concern is not comfort actually, it's safety. Such a narrow seat pitch increases likelihood that your knees are pressed against the seatback in front of you, and I can never imagine that it's safe in emergency. And the ideal bracing position for taller people requires 35" seatback to se...
Jump to postApologies if this has been discussed lately. Should govt regulate minimum seat pitch?

Excuse my ignorance, but can an airplane be stalled in 0 G or negative G maneuver? IIRC the plane won't need any lift in those kind of maneuver, but can the plane be stalled?
Jump to postI’ve seen a lot of posts about trying to make an old design compete with regards to the max, but isn’t that what Airbus did with the neo? And the previous sharklet update? I’m genuinely just asking. Though the 737 is older. But Airbus didn't make theirs enter kamikaze mode just because one sensor g...
Jump to postWith almost $20B, why didn't Boeing kill this ugly frankenplane back in June, when they knew that this mess will cost a lot?
At least they should slap a new gear, make the pylon longer, and add slides, thus avoiding MCAS requirements?
Indeed. As I predicted March last year the MAX would NOT be flying by the end of 2019. And here we are. ANOTHER software "issue". Not to mention the trove of emails leaked recently that imply a major criminal cover up. Mark my words: the MAX ain't gonna fly for a LONG time, if EVER. Would...

Jump to postWhy do we need to test fly a plane when we have immense computational power to simulate it? The short answer is because we *don't* have the computational power... and never will.

Jump to postDoes that mean that already inspected planes have to be rechecked again? That must be truly annoying, and costly. Annoying yes, but fortunately the cost of inspection is small. The AD estimated 1 hour to do the check, and 1 hour to do the paperwork. As far as I can see, no panels need to be removed...

Jump to postI will fly the max anytime as I have confidence it's now safe, Boeing will not let it fly unless they are sure its safe. Sent from my SM-J415F using Tapatalk Seems a bit naive. Boeing insisted it was safe all up until the whole world had grounded the aircraft, including the FAA and announced by the...
Jump to postIt's costing airlines, but does Boeing have to compensate them ? One of the big claims of Boeing in regards to the 737NG was lower maintenance life cost than the A320. One or two pickle fork repairs and the cost of checking for it, with the associated down time, can have an influence on the cost of...
Jump to postSaying it from an engineering standpoint. The pickle fork is designed as a life time part, that is not supposed to crack ever. That is why it was not checked upon. That is why cracks were found by accident, not at an regular inspection. Do I have to make it simpler for you as an engineer? Sir I res...

O'Leary said he is not sure to have any MAX back by summer 2020. That would put the return to service behind Q1 2020. This means behind the timeframe the Boeing CEO has said he would need to halt the MAX-production without renewed permit to fly. Is there something new brewing? Maybe he's talking ab...
Jump to postSo the airlines are to blame for not providing training for a feature that they weren't even aware of?
