How Engineers Reduce Adverse Yaw

[00:00:00]How designers reduce adverse yaw.

[00:00:02]Aeronautical engineers know adverse yaw is a heavy workload for us, so they actually try to help out behind the scenes. They've come up with a couple of clever mechanical designs to reduce this drag and balance automatically. First up, differential ailerons. This is a linkage system where the upward moving aileron deflects at a much steeper angle than the downward one, creating extra drag on the inside of the turn to kind of balance things out. Then we have freeze ailerons. Here the actual leading edge of the upward moving aileron dips down, protruding into the high-speed airflow below the wing. It intentionally creates a huge pocket of drag to help hold the nose into the turn. But, and this is a big but, even with these brilliant engineering tricks, the limitation remains. No design completely eliminates adverse yaw. You still absolutely need active coordinated feet on those rudder pedals.

[00:00:47]Good pilots do not just turn the airplane, they coordinate the airplane.

[00:00:52]That right there is the ultimate goal of everything we've unpacked today. Turning the yoke, that's really only half the job. I want to leave you with a bit of a challenge. Next time you're sitting on the ramp doing your run-up, look out the window and watch those ailerons moving.

[00:01:07]Knowing the invisible drag forces just waiting to ambush your wings the second you bank, how will you approach your next turn in the traffic pattern?

[00:01:14]Remember the physics, remember the extreme danger of a skid, and most importantly, step on the ball.
