FS9 sailplans or gliders lacks flyby wind sound

sailplanes or any plane with it's engine shut down will not allow a wind sound in external view or in flyby mode view.

Trying to come up with a way to add an external wind sound to a sailplane so that I can hear a little zoom wind as the glider passes.

I know the sailpanes are completely quiet in external view, and engined aircraft are too if the engine is shut down.

Since a glider or sailplane doesn't have an engine I thought I would try to get a flyby wind sound hooked up with it by simply copying a wind sound and rename it and place it in the sound folder and then write a [SOUND_ENGINE] section and a [COMBUSTION.1.00] section into the Sound folder's Sound cfg.

My intention was that if I add an engine section to the sailplane, and used a wind wav file in place of the engine idle wav file, as long as engine was running and the throttle at idle, I would hear a approaching and fleeting, wind, wav sound as the glider passed by to add some realism to gliders and sailplanes as they fly by.

This is what I added to the Sound cfg file:
-------------------------------
[SOUND_ENGINE]
number_of_engines=1
eng1_combustion=COMBUSTION.1.00

[COMBUSTION.1.00]
filename=xflybywind_rpm1 <---This is a renamed copy of a wind sound.
flags=0
viewpoint=2 //external spot and tower views
// Sound's amplitude envelope (pair of values)
vparams=0.0, 40.8, 0.132, 49.6, 0.188, 13.6, 0.236, 0.0, 0.456, 0.0, 0.456, 0.0, 0.456, 0.0, 0.456, 0.0
// Sound's pitch envelope (pair of values)
rparams=0.0, 1.0, 0.4, 1.4
----------------------------------
BUT, I still cant get that wind wav file to play. The sailplane is deftly silent in external view or in flyby.
Anyone know what I need to do or adjust to make that external sound wave file turn on?
 
Never tried that, but could it be that since the aircraft.cfg in a glider does not have an engine section, the FS gremlins don't start the engine = no sound

Forgot to say, I also made these engine changes to the Aircraft cfg to ensure the Aircraft cfg had an engine. (Changes below). But still the new wind engine idle sound would not play. Clearly something further must be done to turn the engine sound.

Made this change to the Aircraft cfg:

[GeneralEngineData]
engine_type = 0 //0=Piston, 1=Jet, 2=None, 3=Helo-Turbine, 4=Rocket, 5=Turboprop
Engine.0 = 3.75,0.0, -0.30 //(feet) longitudinal, lateral, vertical distance from reference datum
fuel_flow_scalar= 1.0 //Fuel flow scalar
min_throttle_limit = 0.0 //Minimum percent throttle. Generally negative for turbine reverser

And This:

[fuel]
electric_pump=0
fuel_type = 1 //Fuel type: 1 = Avgas, 2 = JetA

Still wouldn't play the sound even after Ctrl + E to start engine, and using all throttle settings.
 
You may need the [Piston_Engine] section too, along with the [Propeller] section. Just be sure to edit the prop section to where there's no thrust, or you'll end up with a normal powered plane with no prop in the visible animation.
 
Jeeze! Needless to say it would probably take someone with more knowledge that what I have to make it work. But I think it would be nice to have that flyby sound. I know it is a sound that is very obviously missing for gliders and sailplanes.

Although using it as an engine sound in powered planes it wouldn't work since the throttle perameters use actual engine sound wav files. Still, when the engine is shut down, there again a powered airplane gets the deft silent treatment after shut down and gliding and simply pushing air.

Well maybe someone else who knows more about sound writing and thinks it would be a nice addition to gliders and sailplanes will find it interesting. Maybe make a guage or maybe work it through an effect or something, which would probably be more applicable to all types of aircraft, proppeller, jet, sailpanes, etc. But I thought I could actually get it to work by making the wind sound an engine sound thus pegging it to the sailplane spot and flyby mode view.

Anyway, I thought it would be a great idea and I tried.

Thank you Tom, I will give that a try.
 
It probably wouldn't work outside the plane in Tower view. I have seen one plane that had a sound called by a gauge, and that was DCC's latest lightnings. The problem was that if you were watching a replay from the tower, you could hear the dive brake sound as if the plane were in the tower with you, even though the plane was still two miles out. I'm guessing that fooling the sim into thinking there's an engine will be the best approach here.
 
Well I could not get that wind sound to play loaded up as an engine sound. Surely I left somethin out of the Aircraft cfg or the Sound folder's cfg that kept it from playing as an idle engine sound replacement.

The two models I was using to work with to test and exchance files to try to get it to work was that Emouchet glider and the Druine Turbulent from that French site.

Further curious, I did place a wind wav file into the Druine Turbulent's sound folder, in place of the exterior engine idle sound, and it did work. However I wasn't that impressed with the results. It did play the wind wav file. It did give an increasing sound level of wind as the plane approached and then flew by and a descending sound level as the plane flew off. Which not bad, but the sound level as the plane flys off in the distance a half mile away is too loud. In other words it doesn't completely disappear. And after landing in spot view and the plane has completely stopped the wind sound is still playing unless you switch the engine off.

Another thing about it is that there is no dynamic sound connected in relation to the amount of airspeed of the plane. In other words, the sound does not raise as the plane gets faster or decrease as the plane nears stall speed like FS9 models the wind dynamics as heard in FS9's interior wind sound.

It is hard for me to understand how FS9 can handle interior wind sound yet can't peg the same thing to a plane for exterior spot or tower flybys. It is beyond my smarts to venture any deeper into the subject. Although it would be nice to have something like this for the sake of increased realism. Probably a guage would be something that could achieve it, omething I have no knowledge with.

And if it would take a guage and could make it work for exterior view dynamic wind that would work dynamicaly with airspeed, then it could easily open the path for another similar effect such a constant speed prop sound that goes into increased flat pitch sound as airspeed falls off, and decreased pitch sound as the plane builds to cruise speed.

Oh well it was fun experimenting with the idea, and maybe it will spark someone that knows more about these things to bring it on.

I was very impressed with that Emouchet sailplane which remarkably reminded me of a turkey vulture's flying characteristics. And then in flyby mode there was that deafening complete silence as it flew past which reminded me that FS9 planes don't have wind sounds in exterior view. Still though, that Emouchet sailplane is an excellently done model, plane & flying qualities.
