HOW WING WASHOUT MAKES YOUR AIRPLANE MORE STABLE
At first glance, it looks like the wings are straight on most light aircraft. But that’s not actually the case. Almost all aircraft have something called washout built into their wings, and it makes them more stable in a stall.
WHAT IS WASHOUT?
So what is washout? It’s a change in an airfoil’s angle of incidence, measured from the root to the tip. If you look closely at a wing with washout, you’ll see that it twists from the root to the tip, with the root having a higher angle of incidence than the tip.
