ATR72-500/600 Aileron and Spring Tab. How does it work? Explained with 2D animation. ✨follow me on facebook: / mzostudio ✨follow me on instagram: / mzo_studio
Only the rudder and aileron have spring tab. During roll the AP roll actuator deflects the left spring tab to move the aileron and returns it to last position when plane is back to wings level. Unlike the aileron spring tab the rudder spring tab has auto trim function that stays deflected on a new position when the trim is actuated. The elevators dont have spring tab, they have the servo tab. It has the same purpose to relieve pilot control efforts, but the actuation is not mechanically but manually controlled by the pilots using the pitch trim control on the yoke or stby pitch trim on center pedestal.
Elevators are Auto-Tab, servo tab is when the command is the tab. On ATR the elevators are directly commanded. The AP roll deflects left and right Tab. The roll trim is only on one side.

@@forestal Yes, Aileron roll trim actuator is located on Left aileron side.
Good video, very informative.
I did not quite catch the movement of aileron trim tab position in the tripple indicator..how much deflection can be viewed in the indicator??
Nice video
Nice video! Very informative where can you make illustrationc like that and how they move what soffware do you use?
My 2D creation are made by microsoft power point.
Can u show me propeller position during atpcs test in slow motion of video...
Multiple different systems and geometry to do the same thing.
Looks like some pivot points aren't quite moving where they should under deflection but overall gist of operation is correct.
