ACCU-Feel made the Aircraft becoming alive in the truest sense of the word. You have the sound of tire screech when the tires touche the ground on landing, but what is missing is the sound of the tire screech while Taxing by steering sharp turns in high speed, just how the car's tires suppose to screech on curves in high speed. Not only it would boost the reality sound, but it's also important as it makes the pilot aware that he's taxing in a higher speed than his plane can afford, for it risks to tilt over causing damage to the wing. In Aircraft like F18, where the minimum HUD speed displayed is 48, those sounds are crucial on curves to monitor the "un-displayed" speed below 48!

I ask all ACCU-Feel fans, to comment on this Discussion as much as possible, turning it to a pledge and commitment to the ACCU-Feel programmers to fill that last gap by updating this product to PERFECTION

Dude if you taxi that fast in a plane to make the tires screech as you go around a corner sideways you shouldn't be in one
This don't need to be put into Accu-feel as it would be wrong

If political correctness didn't matter (your personal slogan), acoustical correctness does! It's not about exhorting speed tickets or lecturing rules of good behavior on a taxiway to get my pilot's license, it's about the simple FACT that tires on the ground, taxing or not, do screech on sharp curves, (as I also believe how your hands would start to squeak on the sharp curves of a beautiful lady) so are we here preaching behaviorism as moral apostles do, or just calling a spade a spade! If you are that good pilot as your flight experience may allow to subordinate others back into a Taxi driver, you should know by now that IT IS possible to make the plane's tires screech steering sharp curves and WITHOUT tilting over as you may compensate this tilting centrifuge by simply rolling synchronically while yawing on the ground.

Screeching tires are a FACT and facts are to be rightly represented. Freedom of speech is right, but moral opinion on behaviorism are in this "technical" Forum out of the context = WRONG!

Biba,

NorForce is correct, screeching tires are a 'fact' as you put it in car, when going fast around a corner and normally when low on pressure. However on an aircraft you would have to be bombing it to the point of wing overs to achieve anything you might have heard in a car!

Aircraft tyre screech comes from landings normally, certainly its not 'the norm' not when taxing an aircraft

Also Biba, please realise theres some irony and sarcasm and general banter on these boards. Not everything is to be taken literally and I'm sure Norforces comment was tongue in cheek and didnt need the response you have given.

thanks,
Lewis - A2A

Lewis,

don't get me wrong, but I find it really great that there is such a software as ACCU-Feel. As a specialist on product research for end consumers with a M.A. Master's completion in "real life", I'm just some qualified user practicing constructive criticism on your product by highlighting any shortcoming in its performance - free of charge of course... I'm sure any product CEO wouldn't gainsay the fact that outlining such shortcoming is to be assimilated as a boosting enrichment of your products to perfectionism. (as far as its budget allows)

ACCU-Feel is supposed to generate reality, right?! On this topic I again confirm that NorForce and You are WRONG and I'm even willing to bet a whole month's salary on that: Screeching tires on Aircraft in high speed on sharp curves is a physical formula of how wide is the friction surface of the tires and the weight of its bearer, that especially under normal conditions (properties of the ground, wetness degree etc) occurs in heavy Aircraft - in this case bigger one. There are so many cases documented on videos of REAL tests and in a lot of films too, where you hear it loud and clear! Rendering these facts in digital context for this software is an extra heavy work for the programmers. Those retouches mostly fail because of product's short budget. So is it a desperate maneuver to conceal some insignificant product deficit because, you know, the whole thing has degenerated to an average discussion here about "cross-section-norms" about how you are "supposed" to handle an Aircraft, and how are you supposed to express yourself

As to my response to NorForce, I'm sorry if he was offended for my re-comment on his comment... My response was from my point of view mandatory. Generally speaking, in business world, competition often "laminates" its offensive activities with the use of rhetoric and polemic. "Tongue in Cheek" could be conceived as one of its instruments if abused, and if the addressee is in the right, it would be perceived as "direct offense". So who is the "offender" and where is the "offended" in this case, I leave it up to the jury* . (* = Paragon in irony, sarcasm and general banter) As you shared NorForce's opinion that I'm wrong, which became prejudice in advance, your referee is biased AS LONG AS the matter of the screeching tires formula is not a "closed case". If I'm proven wrong, I owe both of you a big apology...If... On the other hand, if I'm right, can you exclude NorForce's sarcastic negation (never minds yours) not having impact on other readers for not supporting my petition!?

Perfectionism is a German quirky property that risks to mute to a "germ" if it gets out of hand

Biba,

I still have to disagree. Please remember this is an aircraft not an automobile. The speeds aircraft taxi at and the brakes used will result in no tyre screech unless you are going too fast and aiming to dip a wing, ground loop and generally have a really bad day before you have even made it to the active runway.

We cannot put development time into something that very few people will hear 1 second before the sim tells you that you have crashed. Its better we spend time on some of the 'mainstream' everyday features that are missing from flightsim.

thanks,
Lewis

Taxiing should be conducted at not much more than a brisk walk, especially whilst cornering. I'm aware at busy airports many exceed that, but never for a turn.

I judge speed by looking out to the wing-tip, and perhaps imagining trying to keep up on foot, doing this I can see from visual clues what my approximate speed is. If Usain Bolt would break into a sweat, and induce a seizure trying to run alongside the ship; slow down. I'm aware that in FSX judging speed in the same way can be a challenge, due to the default airports having few visual references at the side of the taxi-ways, and the runway itself, yet I still find this technique reliable.

Point being with the above; Use visual references to judge speed before initiating the turn.

In my opinion, taking into account the above; absent/inaccurate tyre screeching effects for that stage of commanding an aircraft are minor, to non-issue - As you shouldn't be judging your speed in a turn by how much the tyres are protesting, judge it visually before the turn.

Experience also plays a part too, in flying the same aircraft over and over again, you will become familiar with what power settings start/keep the aircraft moving.

John.

During my USAF days and what I have observed at most airports, large aircraft like the B744, 777, 767 and the new 787, they taxi at the speed of a walking person. I watched some videos of the high speed taxi test of the 777 and they were watching for tire scrub.

On the same subject of screech, I know this is being enhanced in the next update. Is there any time frame on when we might expect it.

Thanks for a great product

Bob

Very shortly Bob, good to hear you like the enhancement.

thanks,
Lewis

Thanks Lewis, looking forward to the update, can you give us a hint on the new features?

Bob

A pity you didn't switch on to this thematic a little bit sooner, you would have had saved this discussion from a screeching overdraft into the wrong direction with this information. I remember the documentary I saw was about a 777 making an emergency landing where it was forced to make a hard turn in high speed avoiding an obstacle with a lot of screeching tires. This was in general my point of focus but the Gentlemen tended to corner the discussion solely in the "Taxing" argument... It's good to hear about the new screeching enhancement in the next update. Thanks a lot Bob!

Lewis, you could have had mentioned that there will be a screeching enhancement in the next update right from the beginning and let us then argue about its results in the aftermath! I really don't understand this discrepancy of denying the necessity of an enhancement in the first place and then this...unless this update was meant to remain "Top Secret" and I've ruined the surprise?!

Hey Biba,

the tire screeching you are thinking of is already a part of accu:feel. And this is going to be fiddled with further, this is what is coming. However your first post talked of on the ground tire screeching and turning a corner which are quite different things.

thanks,
Lewis

As being a German, my translation of technical terminology into English can surely differ from common standards. Yet I doubt if we were taking about different things if we compare the three processes - of touch down by landing, full brake without Anti-Skid and making sharp turns with high speed:

1. Sudden acceleration,
2. Is the same as 1. but in the opposite direction
3. Centrifugal side effect to the axis of tire's rotation.

All three processes have one thing in common: its about the friction surface of the tires on the ground and they ALL make noise! Each one has its own individual sound-print. Calling them all "Screech" is definitively a lack of English finesse from my part, but they do all make noise! My main claim was that some of those sounds are simply missing.
In this case it's no.2 & 3

A perfect example for that wing-tip wiggle you mentioned is the behavior of the standard F-18 in FSX. Compared with the more realistic F-18E SuperBug from VRS, its shock absorbers are like marshmallows! On the slightest sharp turn the tottering is so intense that after few minutes one gets seasick. They ought to put some Barf-Bags on board!
