PapaJu Posted November 28, 2005 Share Posted November 28, 2005 OK so as much as I know about planes and aviation, I wasn't so sure about the answer to this one (given that I haven't flown yet). Anywho, I've heard that the rudder isn't used so much on larger jets, as opposed to props-can anyone clarify this, and why this is? Thanks.

Buddy Spike Posted November 28, 2005 Share Posted November 28, 2005 P-factor and torque. Link to comment Share on other sites More sharing options...
Guest sleepy Posted November 28, 2005 Share Posted November 28, 2005 Crash hit it. But don't use that as an execuse to leave your feet on the floor. Haven't figured out how to get rid of adverse yaw yet. Link to comment Share on other sites More sharing options...
Guest mo7stanley Posted November 28, 2005 Share Posted November 28, 2005 It really varies from plane to plane on how much rudder is needed in any particular situation. I am not sure about jets other than what crash said. In jets you don't have the left turning tendencies so you don't need so much right rudder.

Guest gtyj98 Posted November 28, 2005 Share Posted November 28, 2005 Rudders are still an important control surface on small and big jets. On Learjets, a pilot's leg will shake frantically when using rudder to fly simulated engine-out procedures--and thats with full rudder trim! And with both the C-21 and the C-17, a 'heavy', we use the rudder all the time on approaches similar to your SE prop. For example, when on final and a crosswind is present, the old adage still applies of using ailerons into the x-wind and straigtening the nose with rudder. It's especially important in the 17 on full-flap assault landings, when we land in a 500 ft segment on a 3,500 ft runway. We HAVE to be "stabilized" in order to land--and that can not be done without proper rudder inputs. Link to comment Share on other sites More sharing options...
Guest TheBurt Posted November 28, 2005 Share Posted November 28, 2005 Wanna, As someone has already mentioned, P-factor, torque, gyroscopic effect, and slipstream effect on propeller driven aircraft. A similar thread was started back in Feb 05 under "P-factor". I currently fly the C-130 and the B-727. C-130= very ruddercentric (maybe a new word) even with all engines operating normally, and heavily ruddercentric with an engine out, especially an outboard. B-727 rudder use not nearly as much due to torque and p-factor being almost nil. B-727 also has a very effective and necessary yaw damper, bottom line unless doing x-wind t/o or landing, and engine(s) out rudder is not used very much in the 72.

Guest tentoad Posted November 29, 2005 Share Posted November 29, 2005 Actually the rudders do get used a lot in heavies. The kicker is that the jet does it for you. The DC/KC-10 have 4 yaw dampers. The pilot gets to use the rudders when the jet doesnt know it needs some uncoordinated flight like during takeoffs and landings. Gotta use em for wing engine faiures too. Some guys, me included, use them for Rec AR- especially during limits demo's. Link to comment Share on other sites More sharing options...
EvilEagle Posted November 29, 2005 Share Posted November 29, 2005 Rudder is used a lot in BFM for Eagles as well. That's about the only time you touch them besides taxi. Link to comment Share on other sites More sharing options...

Guest priorE Posted November 30, 2005 Share Posted November 30, 2005 You'll need it in the tweet to get into/outta spins. edit: Sheot, you said larger jets, so never mind. [ 29. November 2005, 20:30: Message edited by: priorE ] Link to comment Share on other sites More sharing options...
