Later models had 13 Kruegers on the Leading Edge.
they are sequenced on both extension and retraction, but it is not the same sequence.
the extension sequence seems to be 1,2,4,5,3,6,7,8,9,10,11,12,13 from Youtube video
I assume you cannot extend or retract at the same time, because of aerodynamic issues - having all Kruegers in the "Barn-door" position at the same time cannot be good for lift
does anyone know ...
Why the sequence is different between extension and retraction ?
and
How are they actuated / controlled ? not by a single drive shaft I assume ?
thanks in advance,
Re: B707 Kueger Sequence
They were hydraulic powered with their own actuators and I don't remember any sequence involved, it was possibly the hydraulic pressure that caused that.

Sounds like a good oral question when the student has gotten everything correct....so far:)

Got a 727 oral question for you:
What’s the only non essential bus on the air
craft ?
The bus that takes the FO to the plane
Drum roll..

That was the actual last question on my 727 FE oral exam at Continental
I was stumped, thinking about truck driving
school until the examiner started laughing
and let me in on the joke
