Engineer, : Hmmmmm...... may have to fly another test flight or two or three........"
Correction: Hmmmmm...... may have to sim test another flight or two or three....
@fdr...I was being factitious. In reference to the NYT article, the test pilot found the aircraft had issues with low speed stall...he recommended adding VG...engineers said software..
my point being, in the beginning, the 747 had low speed stall issues on initial test flights, they added vg tabs to the wings as a 'temporary measure". (and never left)
now, vg tabs continue on Boeing wing designs, as well as showing up in odd places as 'fixes' such as in front of the windscreen....
hence my comments..
Flight test shows stall issues....
Old school Boeing test pilot: "add vortex tabs"
Millennial engineers: 'add software"
Where does the part about "design wings correctly" come in?
