Well try this on for size. Teaching in the DC-8 and 747, IOE, Initial Operating Experience. Both a/c are very susceptible to sucking up things with the outboard engines while reversing on landing, especially the DC-8 so you need to land in the middle of the runway. So the way I taught landings and especially Xwind landings was to line up on final, keep the wings level with the ailerons and use the rudders to crab into the wind. Making small crab angles allowed you to stay on the centerline. Especially on the 747 you could stay lined up and move 10-15 ft and when you eased off on the rudder it would stop right there. If you tried banking to move 10-15ft you had so much inertia it would continue moving left or right. Now you have been working the rudders on final and at the flare you can feel just how much rudder to remove the crab for the landing.

And, although I’m an outsider, rudders might have some value for yaw control.
And Evan always forgets to mention how light, 1.25” pedal inputs give full rudder deflections on some types.
Light, 1.25” pedal inputs result in light rudder deflections in this type.Last edited by 3WE; 2023-03-01, 13:11.Les règles de l'aviation de base découragent de longues périodes de dur tirer vers le haut.

1.25” pedal reversals (kind of seen in the OP) are generally not_a structural nor even a comfort issue. (Mild sarcasm may be present with one word)Les règles de l'aviation de base découragent de longues périodes de dur tirer vers le haut.

Well rudders are a flight control just like ailerons and elevators. If you are in a position where you need max deflection on any one, you shouldn't be there. When i started flying jets I was told you don't need the rudders.
Here's another one: when transitioning into the Hawker 1000 we had to do some landings in the a/c. The instructor told us to trim the nose down on final so that in the event of a go-around you wouldn't have to trim as the flaps retracted to 20 deg. 'Distraction' boom! ground contact. don't believe everything you hear.

rudder (dt. Seitenruder) >> The pedals at your feet, in a Cessna or in a B744. For use only with care and when ct has published the weather for you on final.
aileron (dt. Querruder) >> The difference between a Cessna and an A320. Stick or not, this is the question.
elevator (dt. Höhenruder) >> Ask Flight Captain Sullenberger, with this stick you can be a hero, or dead on impact (cp AF-A332).
And what now is the thing that Evan shouldn't know?
