Pitch vs. trim in flight phases

... From the way some of them talk, it doesn't sound like they've done any recent or serious simming. That's because almost nobody (yourself included) takes simming seriously. Otherwise, your recent tragic crash would have involved more than "half-hearted attempts to recover control". |

... Most pilots are polite, especially those with the much greater experience that is usually required before they can fly aircraft other than tiny tin cans. I find your choice to of the term 'tiny tin cans' particularly telling. |

: BDS writes: What makes you group everyone into the same category here? I don't. But quite a few of the most vocal posters to this group seem to belong to some sort of odd subset of all pilots. Their behavior is unlike what I've seen in other pilots, and their knowledge is also peculiarly limited. I think that other factors besides being a pilot enter into whatever motivates them to post here and behave as they do. Did you fly the airliner, or ride in the back? I was on board, and that's all that was required, since the entire aircraft moves at once. I have flown some of these and the simulated feedback provided is very close to the real thing. Believe me, it is nothing like the toy yoke used on PC sims. But it's still simulation, provided by springs. How can it be realistic? Find me an actual pilot who says this. Most pilots are polite, especially those with the much greater experience that is usually required before they can fly aircraft other than tiny tin cans. I agree that you cannot fly based on physical sensations alone, nor can you drive a car in this manner. Would you agree however that sensations can tell you things like relative speed, you just got a flat tire, your brakes are shot, something bad is about to happen to your engine, your power steering just failed, etc., etc. They can tell you some of these things, but not all. A flat tire produces a very distinctive sensation. However, you cannot tell how fast you're going, or even how much you've changed speed, by sensation alone. Overall, it's a pretty poor indicator for everything. Inner-ear sensations are designed to help you stand and walk, and for those purposes they work reasonably well, particularly when combined with visual input. However, they fail pretty miserably in situations for which they are not designed, such as flying an aircraft. The literature is absolutely constant on this point. About the only thing you can glean from sensations is that a change in sensations generally correlates with a change in status. If you suddenly feel that you are turning, chances are that something about the aircraft has changed ... but you cannot assume that the change is actually a turn unless you can confirm that by other means. Some sensations in flying can be relied upon and they add to the total picture about what is happening at any given moment. No pilot would ever disagree with this. If you disagree, find someone who is a pilot to back you up and you will gain some small level of credibility. Some sensations can be relied upon in a small way. No sensations are actually required. An absence of sensations does not prevent you from flying if you have other sources of information, and sensations alone are never sufficient. This is why motion is not very important in simulation. Motion helps convince a pilot that he is flying a real airplane, just like sound, but he doesn't need motion to fly, and in fact, he is supposed to be able to fly without it. Many pilots here seem to cling to this idea that simulation without motion is inadequate. I'm not sure whether they are really addicted to motion as much as they seem to be, or whether they are just using it as an excuse because it is one of the salient differences between a desktop simulation and a real aircraft. Perhaps if MSFS included motion, they'd find something else to latch onto. You are a fjukkwit. Oh, and BTW, I fly little tin cans, big tin cans and rags. Jerkoff. Bertie |

First, it's generally more than a couple of springs and second, it costs more than the $150 you probably spent on your toy yoke. That's why it's more realistic. Some sensations can be relied upon in a small way. No sensations are actually required. An absence of sensations does not prevent you from flying if you have other sources of information, and sensations alone are never sufficient. No one here has argued against this. Many pilots here seem to cling to this idea that simulation without motion is inadequate. I disagree. What I have seen here is mainly the argument that the sim (and especially the PC sim) is not a true substitute for the real thing - in this case trim function being the latest example. I think you have an emotional investment in arguing against this because your arguments lack logic and tend to dismiss anything that points to that conclusion. When you are backed into a corner you always seem to resort to the thinly veiled "tin can pilot" insult without having any idea of the type of pilot you are corresponding with, or the experience level they might have.

I wonder if a series of small electric motors could be used to spool up bungee tension corresponding to appropriate pressures. Not sure how the big sims do it. -c Not sure myself. It would have to be a complicated program. Even the control surface area is a factor, and each aircraft would be affected differently. Unless I'm mistaken here, since the big jets have boosted controls and run everything through an artificial feel unit for the yokes don't they just install the same artificial feel unit in the sim as is in the aircraft?

Nah, the artificial feel is fairly simple compared to the arrangement in a sim. In an aircraft there's an airspeed input ( some older airplanes have seperate pitot tubes on the tail to feed the feel) that goes to a computer which operates a bunch of arms and levers that give a mecanical advantage type feedback to the stick. While it's similar in a sim, the number of parametrs the sim's computer has to look at to make a feel adjustemnt is enormous. In the airplane it's pretty natural in operation. Even the best sims tend to be a bit notchy and not so natural to fly. Good smooth RL pilots tend to be fairly poor at controlling sims, particulkarly the old ones, wheras guys who are good at flying the sims tend to be automatons and fly the airplane as such. Not a hard and fast rule, but it's the case more often than not. I was in an old three axis sim years ago and noticed the altimeter wasn't moving while we were in S+L flight. I just assumed the sim was acting up and was broken.... Bertie |

Well, the use of it doesn't require any training. However, as CFIs we bang our heads against the wall because students don't trim often enough. This is especially true in the pattern. If you let them, students will build up a sweat holding the yoke with a death grip. -Robert, CFII |

Gatt,
He just marked it INOP to keep people from using it. How extremely dumb of him! I'd run, not walk out of that "flight school". -- Thomas Borchert (EDDH) |

Bds,
I have experience with both and to me (and probably every other pilot on this ng) it is a big difference. Why, oh why, do you bother with the idiot? It's going the same route it always goes (and you're right, of course). -- Thomas Borchert (EDDH) |

Bertie? Here's a great article written by Joe Bill Dryden, test pilot in the F16 program. Dry does a very credible job of explaining artificial feel in rate control systems as opposed to displacement systems. I believe this will help clear the air a bit. http://www.codeonemagazine.com/archi...rol/index.html -- Dudley Henriques |
