Outer Wing Fold Latches
Refer to Figure 22
These latches are automatic, and should never require
operator action. The latches couple the outer wing to the
inner wing when folded, preventing movement of the
outer wing during transport (the two outer wings might
otherwise be able contact each other in unusual
circumstances).
When unfolded, the latch pivots out and down
(disengaged). During fold, the outer wing folds first, until
the stop posts
contact each other. As the inner wing
then folds, and passes vertical, the latch swings into
engagement on the pins of the outer wing stop post.
At the start of unfold, the latches restrain the outer wings,
causing the inner wings to unfold first. As the inner wings
near the ground, the latches fall away, allowing the outer
wings to unfold.
