Will ED include the Hornet "whisle" sound effect?

It occasionally seems to make this noise at certain angles. Sounds similar to the whistling noise the F104's are known to make during flybys.

They sure got the whine of the pony

Sounds more Like a groan than a whistle. Would be cool if it could make the sim. But that sound happening in the right circumstances is key. So if they can do the Mustang whine, they should be able to incorporate this one too. I have to ask because I dont know, is this common with the F18 or was there a ground hog stuck in the intake?

no, it sounds like a howl.

it's the Engine Howl for the engines being in idle with no interfering noise, as well as air temperature and frequency.

Discussed previously in another thread, don't remember what the conclusion was regarding being done for inflight/flyby sounds.

But it also occurs during startup, and that's already been demonstrated in the startup video published by Wags.

The sound has to do with the speed of inlet air being faster than the first stage of the compressor... kind of the opposite of a compressor stall, but a similar sound, because the compressor blades are not actually compressing (fully) in both cases. Basically, the sound you hear is turbulence over compressor blades. Wiki VGV (variable guide vanes) or take a look at "AgentJayZ" on youtube. He has some amazing videos that explain how they work (specifically on compressor stall).

TL;DR - Happens when the throttle is reduced dramatically at high speeds.

Hence Idle Passes..

Well I still hope they model it haha

The whistles go woo

At certain speeds/engine RPM like in the Vulcan and other aircraft, as the engine's mass flow rate increases, the air is being forced down a narrower hole until it hit the divergent section at the speeds mentioned above. Imagine blowing over the top of a bottle, it has the same effect (a resonance).

The ViVGs are all about engine start up and up to certain engine RPMs to allow the compressor to operate as close to the blade stall margin as possible without causing them to stall. As far as I'm aware it does not have any bearing on the howl from the intakes.

Eh not exactly. I could see it being at a lower RPM but it sure doesn't sound idle.

Here is another video example and there would be no way they were idle:

Another possibility would be the way the air is hitting the turbines at a certain RPM. I'm sure it has many factors.

Reference vulcan howl?

I was recently watching F-18 solo aerobatic show. Whistle sound was really the only thing you could hear while descending at idle power with gentle turns. The engines made so much noise while applying full power that it made some snow fall from roofs.

The engine has more than three settings folks (AB, MIL and IDLE)..

A lot of aircraft will howl at just the right throttle setting and in certain conditions, like the F-15. F-15's will howl on approach similar to the Hornet. See below...this is fairly minor for an Eagle howl, I've heard it much, much louder.

You can also hear it at 2:06 in that video.
