Lead Sled said:The MU-2 and Beechjet do not have spoilerons - Lear 35s and Boeing 727s have spoilerons. They use straight, old-fashioned, honest to goodness spoilers and nothing but spoilers for roll control. They use small trim ailerons for roll trim.

It's been 20 years since I was last in a 727, so I don't remember the exact flap setting when the spoilers started working in conjunction with the ailerons. Regardless, when you've got spoilers and ailerons working together - you've got spoilerons.Donsa320 said:Gee, all that time in a B-727 and I never knew I had "spoilerons". Please educate me some more. <bg>

I knew you knew that.
The Lear 35 also has a similiar system, it's been 10 years since I've flown one of those, but I believe that you get differential spoiler operation to augment ailerons with flap settings greater than 20 degrees.

You're right, it has been a long 20 years and a lot of water has passed under the bridge. As I remember, the spoilers started to augment the ailerons at 7 degrees control wheel movement. They told us that the combination of ailerons and spoilers were called spoilerons as they are in the Lear 35. Oh well, I stand corrected.Donsa320 said:It must have been a long 20 years, good buddy, the spoilers always work with ailerons in a 727. As they also do on DC-9's and A320's, etc. I think you are confusing that with the progressive lock-out of the OUTBOARD Ailerons as you get less than flaps 15. However the INBOARD Ailerons continue to function at all flap settings, as do the roll spoilers. Differential spoiler for roll control augmentation is rather common and I'd never heard that referred to as "spoilerons". They are totally separate surfaces.
