I feel like this is supposed to be in the real world aviation category but this is my question why are the ailerons on the A380 in three parts like this.
Thanks Goran
Because the plane is huge, thus the ailerons need to be huge as well.
Okay thanks fir the help.
The plane is so big it basically some areas have to be designed different for the plane to work.
The link that you credited explains it…
These ailerons are split into three and are programmed to make the plane more handy and agile when in the air. According to A380 pilots Airbus has done a really good job there ;)
They get mor sirface aria, and since one massive one would take so much power to move it is split up, they also get more presise control, by only moving one or two for small movements
All these answers above are mostly incorrect.
Because this plane is massive, it is very heavy. Imagine turning a cruiseliner with a kyack paddle. This is what it would be like for only one aileron. They’ve split the aileron into three separate pieces to reduce work on the hydraulic and electrical systems, as well as reducing stress on the wings and airframe. With these ailerons being near the wingtip, the can also flex the wing to change direction. The ailerons are sometimes at an angle during cruise to reduce wing loading. This is controlled by the FBW system. Airbus has experimented with something like this before, in the A310. The A310 used spoilers instead of airlerons to roll, but was inefficient because of increased drag. Here’s an answer I found on the web:
On a large aircraft, at high speeds the material of the aileron can be flexed so much as to nullify or even reverse the direction of change of lift, which causes significant issues. The further out on the wing an aileron is, the more it is subject to these forces. For high-speed aircraft, this necessitates an outboard/inboard aileron, with the outboard being locked out at a certain speed limit. On the Airbus A380, the downwards motion of the outward aileron is locked out at 240 KIAS, and upward motion at 300 KIAS.
Hope this helps expand you knowledge of aviation!

You’re pretty ridiculous…
I’m not speaking about you @MackenzieRodgers
Here’s a question I found on the web:
What do you mean?
It makes sense for ailerons to be as far out as possible on the wing from the fuselage. By increasing the distance from the fuselage, the perpendcular distance increases. Since torque is given by force x perpenicular distance, a larger perpendicular distance would provide a larger turning force and thus better manouvreability for the plane.
These ailerons have the most beautiful movements!
