777X Landing auto-fold of wingtips

arrestor hook next.

Then all the pax seats would have to be installed facing aft. That would freak out most people.

Hopefully Boeing didn't farm out the software to Joe Bag "o" Donuts software company.

Those engines are huge! They are 13ft wide, wider than the body of a Boeing 737 

Just look at this pic of the GE-9X on a 747 https://www.godsavethepoints.com/boeing-777x-ge9x-engines-larger-737/


Was anyone else let down by just how little of the wing actually folded up?

You don't realize how big those engines are until you see them on the 747 ! Even after seeing the 737 graphic ! Wow !

I love wing flex.  I like to look out of the window on take off and as the wings take the weight of the aircraft from the earth remark loudly "wow! look how much those wings are bending..."

Is the problem not Boeing's electronics but Boeing's software?
Given it's such a small amount of wing that folds i'm sure one of these could happily remain in the air should one or both fold in flight.

They are actually flapping!   The ornithopter effect has been a closely guarded secret among aerodynamicists.

Wasn't there a case once when a Crusader took off with its wing tips folded up? I can't recall if it was land based or shipborne, but it must have been pretty crucial.

Naples.  August 1960.

Wow, and it happened half a dozen more times too?

Didn't the launch crews ever check before clearing them? 

It'd NEVER happen at a RAF station, every flight has to be given an OK by the threshold caravan before it's cleared onto the runway.

I've actually done those visual checks myself more than once. (Thanks so her who's the RAF's Best Air................Oh,  you know that already? Sorry.)

I'd like to see them do the trick that the FAA did with their Scimitar display team at Farnborough once.

They took off as  four-ship, did their display and landed as two, two ships, from OPPOSITE ends of the runway! As they approached each other each of the aircraft folded their wings and passed between the opposing pair! 

The gasps of the crowd were almost audible above the scream of the eight Avons. 

Can't see that being allowed nowadays, even if we had an aircraft capable of doing it

Then there's this.

Turns out it had less to do with design flaws than it did with a McDonnell-Douglas style
keep it cheap mindset coupled with a GE maximize stock value corporate culture.

The 737MAX flight control system computer and software are not made by Boeing,
they're from Collins to Boeing specs.

Boeing and EADS don't produce their own electronics, it comes from other companies;
Collins, Honeywell, Thales, Smiths, and Lucas amongst others. Some of it is to the
airframers' specs, some other components and systems are COTS.

The 777X wingfold system is designed and produced by Liebherr-Aerospace Lindenberg.

BTW unlike the 787 with its problematic partner system for design and manufacture
of major components, the majority of the 777X is in house with the new composite wing
being manufactured in a new facility here in Everett and the fuselage being assembled
using a new automated robotic system, again here at the plant.

Yes, but then they are all put into Boeing aircraft.  The flying public don't know who made what.  They just saw that a Boeing crashed and therefore would rather ride in an Airbus.

I'd love to see a film of the interview the pilot had with his C.O. after that take off

Here's the thing, in the case of the 737 Max, that software wouldn't have even been necessary if not for the design flaw/problem that existed in the aircraft. This is to say that there's plenty enough blame to go around.  I'm not a Boeing hater either, I love Boeing aircraft but they created a monster pushing the 737 into realms it shouldn't be when they should have just designed a new aircraft from the ground up.
