If you do the math on a IV, you get 83-85 knots for a final approach
speed. 100 knots down final is 1.5 VSO!
Lancair lists the landing roll for a IV at 900 feet. Is that with a
"standard approach" or with the 100 knot approach speed. I doubt you
could get a IV stopped in 900 feet with a 100 knot approach, even if you
touched down at 85-90 knots.
So the question is, do IV's really have a dirty stall of 65-67 knots,
73-75 mph?
Do Legacy's really have a dirty stall of 58 knots, 67 mph?
What do some of the Legacy and IV owners report as their observed dirty
stall?
