"Dynamic Stability is the Aircraft's response over time." Best definition I ever heard.

Nice video. But wrong explanation at 3:25. When the aircraft is put into a roll on either side, the yaw happens on the opposite side. Which is why it's called the adverse yaw. This is because the drag on the high wing (which is the right wing if you are turning left) is higher as angle of attack/camber is higher for this high wing. This causes the high wing to move slower than the low wing, causing the plane to yaw towards the side of the high wing (which is right if you are turning left). What the speaker is referring to here is the changes to the horizontal and vertical component of the lift vector as the plane tilts, and that produces a sideways force to make the plane GO LEFT, not turn left. This horizontal component of the lift acts on the Center of Lift of the plane. Which is precisely why you are taught to apply coordinated rudder when turning to counteract this adverse yaw. This is more pronounced in sailplanes. Keep that ball in the center, people, so your butt is pushed down into the seat, and not to one side. 🛩️

Nice video! I have one remark - swept back wings and dihedral angles can make the dutch roll mode even worse due to the dihedral effect (which is the interconnection between roll and yaw). To eliminate dutch roll, the pilot needs to make slight rudder inputs, sometimes so slight that he can't really perform it. That's why swept back winged airplanes have a yaw damper, which is a part of the flight control system/autopilot (whatever you like to call it). It makes all the needed inputs and provides a safer and smoother flight, transparent to the pilot.

would you do some questions like If it is desired that the damping constant and undamped natural frequency of the aircraft’s Dutch roll should be 0.6 and 1.4 rad/s respectively, determine the state feedback matix, K, to achieve this using either Matlab or theoretical calculations.

At 3:31 I don't understand how the leftward yaw is happening. Shouldn't it be in opposite direction if explained by adverse yaw.
@JxJAVIATION

This is case of yaw due to a roll. The Lift Vector gets tilted towards the left so there is a horizontal component of the lift that tends to yaw the aircraft.

@@JxJAVIATION Just to help this is actually the opposite. It's called adverse yaw. If an aircraft rolls to the left, the left aileron will be up and the right aileron down, this produces a forward component of lift on the left wing. Meaning left roll creates right yaw.

I can't understand what you said at around 3:47 to 3:48 because of your accent and there is no captions: you said "the flight path after the lateral ?????" than you said a word which I did can't figure out because of your accent. I mean no offense but what was it that you said? because that word is throwing me off, I can't understand what's going on. Anyways if you can get back to me that would be great. Love your videos!
