Grandfathering design and requirements were taken to a new level for the all new 777X & DOA’s are all over the place, certifying huge “minor” design changes with limited FAA oversight, special conditions and 27 yr old requirements.
Nobody wants to be the messenger, fearing to hurt the company it’s (nice) employees and the great looking 777X. If Boeing is serious they’ll let JATR do a review of 777X certification. Shouldn’t take very long, I think they can do a lot of copy-paste..
Exactly, which is why Clark said he wont accept a 777X aircraft without a 13 to 16 month testing, and not likely in 2020.
The manufacturers cannot keep building aircraft in flight...
Getting back on discussion...
all of this topic on stab trim/MCAS...this was never meant to be a system to control stall, or be very active to control the ac.
Set the green band on TO and let the AP stab balance flight with altitude and decreasing fuel weight.
It was a nice convenience....
Look what it turned into...,
On a side note, there is a news entity reported that the Boeing "NMA" is proposed to be a 767-400 metal fuselage with composite wings, and large engines with a lift kit on the landing gear....
Enter the 767X
