Do I get the point you are trying to make?.......no, absolutely not, not even sure you are actually making one.

Why is a rudder a weakening structure? this makes no engineering sense at all, it is no different to an aileron or an elevator.

What is the useless movement action?

According to you the planes you watch use rudder for yaw on the approach, in actual fact the rudder is barely used at all in modern aircraft, yawing your way down the localiser would be a very uncomfortable experience for the passengers with all that yaw/roll coupling, simply use roll to correct directional deviations.

How long ago were you a 'live' passenger in a cockpit....to be honest the rest of your 'point' sounds like delusion........are you raaaid?

Take it easy
 

Panicking BongoDriver? I've seen that before the denial of their world gets threatened. I hope you're not caught on that too. Don't you know this world is just a cover-up? Maybe I opened your eyes. It explanes the stupidity of this world, doesn't it?

Definitely raaaid, all is clear now.

Over and out.

Faman, you are just wrong on all points you wrote... have fun with your world!
