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.

Durn it, I was going to let the Krueger flaps go, when he explained it, as
something I really didn't need to know. Now you bring it up again, and now
I want to know! g

What the heck are Krueger flaps?

Flaps the hinge at the bottom from of the leading edge and
swing down to make a more curved section. Slats are
sections of the leading edge that move forward making a
slot.

Ahaa! I thought they were all slats.

Additionally, on B-727 and B-732, the Krueger flaps will droop down after
the hydraulic pressure is shut off. Turn the hydraulic pumps back on and
they retract quickly. More than one mechanic has been hurt this way.

Doug,

Re-read his statement. With flaps 2 selected, leading edge slats 2&3,
and 6&7 are deployed. The remaining slats, as well as *all* krueger
flaps, are retracted.

Happy Flying!

Somewhat correct Doug. At Fl 2, only slats 2,3,6,7 extend. At Fl 5,
remaining slats (1,4,5,8) and all LE flaps (1-6) extend. Retract sequence
is reverse.

Doug, I had edited my original post, and should have mentioned that the
kruegers get retracted when changing from flaps 5 to flaps 2.

At flaps 2, L.E. Flaps 2,3,6 and 7 are extended, and at 0 flaps, these get
retracted also.
