judgement, numbers, findings, equations
"The pilots rated it as just the wrong side of firm, possibly generating some 'bad FDAP numbers'."
The pilots were confident that it was unlikely to be a damage causing touchdown.
The mechanic's inspection did not find anything.
BTW:
My understanding of the 'sink rate' parameter is that it is not simply the vs, but involves a more sophisticated calculation - it is a measure of the landing gear's rate of closure with the ground and resolves both the translationary motion of the airplane (= ~vs) and also the angular velocity of the ldg gr, i.e. rotation about lateral axis, due to the landing flare.
