Steering on the taxiway
Hi Mx!
Different aircraft respond differently to rudder input whle taxying.. Heaver aircraft take more "push" to get turning, and tend to want to keep turning, more than light ones, especially twins with engines out on the wings. (kind of a "flywheel" effect...) In some, the nose wheel steering is connected to the rudder pedals with springs (Cessna 172) so the steering input feels vague and differential braking is used to assist tight turns. On others (Piper Cherokee) the steering is hooked direct and is very positive. You have to be careful to get the rudder centered before you allow the nose wheel to touch when you are holding rudder in a crosswind landing. and... .....for the record..I find your questions here to be reasonable and the (correct) answers posted will be of some value to You and the many who lurk here.. I am having some difficulty understanding why some here find it necessary to chastize you for being a "sim" pilot. I know some local "sim" pilots who would love to do the real thing, but are unable for various reasons. If that is your circumstance, I hope it is temporary, and you may experience the thrill of piloting a real aircraft someday. I am a pilot, have lots of hours in sims, and I am fortunate to have a clean medical and my own plane, - at this time in my life. It has not always been so, and there will be a time again when it is not so..... Ignore the rants, there are some here that will answer your question properly and correctly.. ....and... just so there is no confusion.... very hot brakes don't stop very well.... and 16 Knots is WAY to fast to taxi any aircraft!

I understand that steering mechanisms vary considerably from one aircraft to another, but I'm still curious. In this case, I'm wondering about a Baron 58, the aircraft I fly in my sim (most of the time). I note when taxiing that the aircraft seems to oversteer, especially as speed increases. That is, I'll move the rudder to straighten out on the centerline of the taxiway, but the aircraft still continues to drift slightly in the turn and overshoots the centerline. Is this the way the real aircraft works? If so, what causes it? I should think that if the rudder pedals turn the nose wheel directly, it would be hard to overshoot unless the nose wheel actually skids or something (?). This isn't happening at high speed, it's like 16 knots or so (or does that count as high taxiway speed?). |

"john smith" wrote Depending on the size of the aircraft and the engines, only small increases/decreases (+/- 100 rpm) in power are necessary if applied at the correct times. So why are you trying to tell him how to fly a simulator? I don't get it. -- Jim in NC |

"Mxsmanic" wrote It does appear to work that way on the Baron. It is only a program./ Someone wrote it wrong. Do whatever you have to do to make it work. Even better, fix the program. Or go ask the simulator folks how it is supposed to work. -- Jim in NC |

wrote If it wasn't for all the silly replies from Mxsmanic the answers to his question are often very useful. There's lots of competent pilots with a wide range of knowledge in these groups. I can't decide if I should read useful replies or ignore the lot! So start a new thread. The problem is all of the people that give good answers, by replying to the nut. It is going to take discipline to get rid of him. Even if you know a good answer, it is NOT the right thing to answer it in response to his post. Go start a new thread, and give the answer as a hypothetical situation, or something. I know everyone wants to talk airplanes, but really, he needs to go back to the simulator group. Like has been suggested, there have been a lot of people, good people stop reading, because of the annoying nutcase. To get rid of a troll, you can not answer him in a dignified manner, no matter what. Make fun of the question, insult the person, or don't answer, but don't treat the question like a real question. It takes restraint. JMHO. -- Jim in NC |

On others (Piper Cherokee) the steering is hooked direct and is very positive. You have to be careful to get the rudder centered before you allow the nose wheel to touch when you are holding rudder in a crosswind landing. As far as I can tell, the Baron has a direct connection from rudder to nose wheel. The part I don't understand is how an aircraft can overshoot in a turn if the rudder is connected directly to the nose wheel. Either the wheel stays put, in which case it must skid a bit as the aircraft continues to turn, or the nose wheel turns and forces the rudder pedals to move in consequence (which I would not be able to feel in a simulator). Do you know which way it works? I'm getting better at turns. I try to anticipate enough in advance that I don't keep turning past the centerline. Oddly enough, it seems to be more difficult to turn on the ground than it is in the air. Maintaining speed is irritating, too. Sometimes I hit it just right and the aircraft just putts along at about 11 kts, but finding that sweet spot consistently is difficult. And with long runways and large airports, one is rolling about for quite a while at 11 kts. ....for the record..I find your questions here to be reasonable and the (correct) answers posted will be of some value to You and the many who lurk here.. Thanks. I am having some difficulty understanding why some here find it necessary to chastize you for being a "sim" pilot. I know some local "sim" pilots who would love to do the real thing, but are unable for various reasons. It's the nature of USENET, and I seem to attract more of the standard USENET kiddies than most, for some reason. I stopped paying attention to the children years ago. There are always a few people who want a serious discussion, if one sifts through the noise. If that is your circumstance, I hope it is temporary, and you may experience the thrill of piloting a real aircraft someday. I hope so, too, but I'm not very optimistic at the moment. I am a pilot, have lots of hours in sims, and I am fortunate to have a clean medical and my own plane, - at this time in my life. I hope you didn't have to wait long. While I suppose that flying at 70 might be better than never flying at all, it seems like a long time to wait. But it is so expensive that few have the means early in life, and conversely many don't have the medical later in life (the medical requirements are rather exaggerated, but there they are). ...and... just so there is no confusion.... very hot brakes don't stop very well.... and 16 Knots is WAY to fast to taxi any aircraft! Hmm. It seems so slow. How about 11 knots? I go faster than that on a bicycle ... why do aircraft have to taxi so slowly? -- Transpose mxsmanic and gmail to reach me by e-mail. |

In spite of what a lot of people think, you can still steer a
non-nosewheel-steering aircraft like a Cirrus and others with the rudders at taxi speeds. You may the brakes to turn with the wind, however. And contrary to how many are being taught, you don't need the brakes on the beginning of takeoff run to stay aligned with the center stripe. |

It takes restraint. Lordy it takes a lot or restraint, especially when the nutball questions the real world..... Gotta pat myself on the back, I have not and will not reply to anything directly, only determine to remind new people that I see that they are dealing with a troll and gently remind them to ignore him, not answer his questions and so on. And as Jim says above, the new person can easily start their own threads. Yes, some lurkers may not like it, and personally, I don't care how good the questions he may ask, the lurkers DO HAVE A KEYBOARD and can ask the questions themselves. I also re-iterate, I can't imagine a pilot not helping a fellow pilot, armchair pilot or even a sim pilot, but this guy is beyond these categories when he starts his combative answers without having any knowledge of the real deal.

: Historically this has not happened and my guess is that it will not. If you notice there are several very valuable folks that are not posting here anymore and my guess is that this freakn' MXidiot has something to do with it. Yeah, unfortunately you are right, one thing for sure, the folks not contributing are very much missed..... Maybe as more see what we as a group can do, the less responses Mx nutball will get and those folks will come back onboard. Jim in NC I see is giving heads up about Mx's history, the more that does this, the less answers he will get, to the point that maybe NOBODY will respond to his posts. It's bad enough I am adding to this by trying to drum up non responders and not talk about aviation related stuff, but somehow, someway, we regulars CAN take back the group with the power of peer power by ignoring this nut. I'd love to start a censored list where the idiots could be sent off to pasture (let the bleeding hearts flame away) and the real questions about piloting our real aircraft could continue like it used to. Just .02 I think this is called moderated, don't know enuf about newsgroups to figure out about moderated groups. Just know enough to be dangerous.... Allen |
