Strange scraping sound on touchdown

[Rich]

Ranger75, 3.5 kb is what I have for fx_tchdwn_s_fx with no sound mentioned in it.

It would be interesting to see what your 2.5 version contains but I rather suspect nothing sound related there and your sound problem is elsewhere.

Have you tried moving your 2.5 version out of FSX to desktop to see if you still have the problem and move it back if it does'nt fix it.

[WarHorse47]

WarHorse47, are you using Fs9 or FSX or both ???

FS9. Not ready yet for FSX.

WarHorse, ok thanks that's what I thought.

[fx_tiremark_6.fx] is not a default Fs9 or FSX effect it must have been introduced from elsewhere the Fs9 Sea Fury is one that loads it in Fs9 that incarnation will not work in FSX which is possibly why it does not appear in FSX effects.

Do you have the Fs9 Sea Fury ???

FS9. Not ready yet for FSX.

I was stumped looking for the sound file causing the irritating touch down sound at some airports. When WarHorse identified an effect file as a possible culprit, I looked for changed file sizes and dates in that folder, and found fx_tchdwn_s. The ‘corrupt’ one does indeed refer to a sound file [ai_touchdown2.wav] which is not in my sound folder.
Flying circuits at CYSN in the Duke, default Baron and other aircraft, with the good and then the bad fx_tchdwn_s files installed in FSX, led to the conclusion that this was the source of the problem, at least on my computer. We await the reply from DL to see if this is the same one there!

Thanks Rich, (and all!)

Just literally dashing out the door - can't fire anything up to try the fixes till tonight - but as per Rich's request:


[EFFECTS]
wake=fx_wake
wetenginewash=fx_spray
water=fx_spray
dirt=fx_tchdrt
touchdown = fx_tchdwn_s, 1
windshield_rain_effect_available = 1

I often edit the touchdown effect - I hate that big white billowy cloud one often gets with most a/c - usually with the Alphasim Scimitar's, has a nice puff of smoke. But in this case, I left it stock ...

Thanks again!

Ok there is no problem with the Flying Stations Sea Fury or the sound sets used.

Case closed.

Ranger75 glad you got your sound sorted.

Sorry - I never intended a big forensic on the Sea Fury, but my case is no more closed now than when I asked.

All we've ruled out is that Sea Fury isn't the issue - which I said all along. Just because the issue got manifested with the Sea Fury, never had me think the Sea Fury was the cause of it.

Furthermore, whereas Ranger's issue varies by airport, mine is same for a number of aircraft on ALL airports/surfaces.


That said, I'll investigate the size/format of the fx'es mentioned. I'm curious, though, if fx_tchdwn_s_fx is corrupted, is replacing it as simple as hunting for that file on original disks?

thanks,

DL

[WarHorse47]

Do you have the Fs9 Sea Fury ???

There is none...from Flying Stations for FS9...that I am aware of.

WH,

I believe Rich is asking if you have the FS9 Sea Fury by Hanvey, Barry, and others. It's a freeware version, available (likely among other places) from Flightsim. He's not referring to a Flying Stations FS9 Sea Fury. There are some repaints hosted there for the aforementioned FS9 Fury, but they didn't do one for FS9 per se.

[Rich]

WarHorse, The Fs9 Sea Fury is not a Flying Stations model, a search on Flightsim.com for Sea Fury will turn it up, I re downloaded it yesterday. It has a number of updates available.

Boy, am I confused

I thought this was a thread on "strange scraping sound on touchdown" which someone pointed to the Flying Stations Fury - which I love to have, but not until I get FSX (after I replace my computer) - but now we're talking about the freeware Fury by Hanvey, Barry, and others...

Yes, I have the freeware Fury. It's in my "hangar", but I haven't flown it for some time.

--WH

[Rich]

WarHorse47, you were talking about a effect causing problems with sound or some such and deduced this effect caused the problem.
fx_tiremark_6.fx

You said

"I encountered this in FS9, and traced the source to the effects file.

Here are the first few lines of the offending fx file [fx_tiremark_6.fx].

[Library Effect]
Lifetime=5
Version=2.00
Sound=5
Sound Param=13

It's possible these days for a stock effect file to be overwritten and shared by several a/c."

That effect is installed by the Freeware Sea Fury !!! which I suspect is where you got it.

[WarHorse47]

Not sure where I got it. Lot of strange stuff going around these days.

The issue I encountered was with the AlphaSim Typhoon. Every time I landed, I heard this crashing sound which I traced back to the effects file mentioned. It did not produce a scraping sound, but more of a hard bang when I touched the runway.

--WH

[Rich]

More or less what I just got when I tried it in FSX.

That effect is defiantly installed by the Freeware Sea Fury in Fs9.

Edited the effect file thus

//[Library Effect]
//Lifetime=5
//Version=2.00

//Sound=5
//Sound Param=13

[Library Effect]
Lifetime=5
Version=2.00

[Controller]
Cockpit=1
VirtualCockpit=1
Spot=1
Tower=1
Map=1

Get no crashing/scrape sound but do get the tire marks on touchdown.

[delta_lima]

Just to make things clear (thought they were .... )

Yes, the thread is indeed about strange scraping (or other abnormal) sounds at touchdown.

No, the CAUSE is not the FSX Flying Stations Sea Fury.

But (at least in my case), the sound occurs when I fly the FSX Flying Stations Sea Fury. Hope we're all clear on the difference between A and B occuring at the same time, versus A causing B ....

So, obviously the issue lies "upstream" of the FSX Sea Fury's actual aircraft install. Someone mentioned checking out fx_tchdwn_s.fx. Here's the contents of mine, which is 3KB in size:

So, thinking it may be pooched, I attempted to swap the existing fx_tchdwn_s.fx with a fresh one from the FSX DVDs. I've searched the two FSX DVDs ... this file doesn't appear to turn up.

So, if this might be the problem, I can't find a way to replace the file to determine that ... sigh.
