During the flight test phase of the 777, I remember hearing that Boeing
was experiencing some trouble with the aircraft's high-lift system.
Specifically,

	1) the test pilots encountered buffetingwhen the flaps were deployed
	   by a given amount, during certain approach conditions; and
	2) the wings generated more lift with the leading-edge slats in the
	   sealed position than in the slotted position.

Presumably, these problems were corrected before United took delivery of the
aircraft. Anyone know what solutions were developed?

Thanks
