It's been a long time for me also, but I'm sure the slats were one
piece, with five roller guides per wing. I've never seen a de-ice
boot on one.


I saw them on a USMC or Navy T-39 in the mid 1990s. I bet they add a ton of
drag.

I used to work on A and B model T-39s at Langley AFB in the mid 70s. The slats
may have been made up of 5 segments each, but they were one piece as far as I
could tell. They pushed in as one anyway.
