So long as the LE has not been dinged, that isn't much more than a minor drag count rise, and from my testing, it may not even be that. Would love to see the ANM data. Takeoff would be slightly longer, marginally,. It is fairly uniform across the span so don't expect much in the way of Cp, root bending or torsional loads. Would add some Veeze to the TO and ldg, but wouldn't lose sleep, so long as pax weren't looking out the window..they pay $$$ to go fly the white rat,...
Don't mess with LEs, don't fluff with TEs near ailerons... But everything else is surprisingly benign. Fluffing about with an engine pylon has more low speed concerns...
If anybody gets a schlieren of the shockwave, that would be fun to look at. It isn't where it should be on any of the supercritical sections, CFD suggests it should be around .75C, it just ain't. If the B74 had gone supercritical other than the late 90s test that Joe Sutter pushed for, then that may have had a shock in about the right place [plaice?] Look about 0
55C for most SC sections.
This one would have moved forward a couple of percent
