The design of its mainplane has basically been inverted, with a raised part used on the inboard finish to encourage move below the wing, whereas the outboard part now dips to discourage it (inexperienced spotlight approximates the form of the previous design). The chord and geometry of the flaps thereafter have additionally been optimised to benefit from this.

These adjustments are seemingly designed to cut back the wing’s pitch sensitivity, tune the Y250 vortex that’s shed on the mainplane and impartial part’s juncture, plus enhance move out and throughout the entrance of the tyre.

Not remoted to simply its new design, however actually noteworthy, is how the staff has additionally diminished the peak of the flaps on the outer edges, in order to melt the tip vortex and scale back drag.
