Especially looking at those new plots of mine,
- from 20:40:10 the left rudder peak values show a decreasing line over speed, as we expect.
- This is a trend up to 20:40:30, with exception reacting for 2 heading bumps to the right.
- Only at and after 20:40:30 this known "violent left push" leading to the mess is outstanding.
Now if a zig-zagging between -5 and -13° rudder in initial roll, then moving btwn -3 and -10° in the later roll is typical on that xwind values, I have no idea.
How much inch of travel is 10° rudder pedals?
engines seem stable
speed has unsteadiness at 4-5 points, looks like going along with those heading variations - gust or wake turbs ... so it was not totally steady air, but also not drastic.
no brake line values, no spoiler readouts to compare a right assymetry
Don't think we find other hard facts from it. But how do I know...
