Note: When 2 degrees of flaps are used, half of the slats get retracted ,
with the remaining slats (and the Krueger flaps) retracted with a 0 Flap
setting

You sure about the Krueger flaps? My library is packed away for remodeling
preventing me from looking it up, but I'm sure only slats 3 &4 are extended
at flaps2, not the Kruegers.
