F-35 Lightning II coming to the airbase close by for sound tests

[ARCHIVED THREAD] - F-35 Lightning II coming to the airbase close by for sound tests

Posted: 4/21/2016 5:55:17 AM EDT

In four weeks, two F-35's are expected to conduct sound tests at two Dutch airbases, Volkel and Leeuwarden.

We are lucky to live in the eastside direction of the base and wind is mostly coming from the west here.

So I expect they only come over my house once they are in their landing pattern.

Are there any members here that live close to an airbase with F-35's stationed there? What are the soundlevels compared to an F-16?

Especially the differences in landing and taking off.

WHAT? I CAN'T HEAR YOU!

Seriously, one of the loudest planes I've ever heard... And I've been around aircraft my entire life. It is louder than a B-52D doing a water injected takeoff. F-16's are just a whisper next to the F-35. Not a whine, high pitched noise, but a gut rumbling blast of sound that carries a long way.

For example, at the commercial airport that uses the Eglin AFB runway (initial training base for the F-35), when one is taking off, you cannot carry on a conversation inside the terminal which is a half mile from the runway.

Good luck!

In before the disappointment.

Yup, I agree. Have lived by Eglin for 40 years. F-4's, F-15's, you name it. Nothing like the F35, even a normal take-off is like a shuttle launch.

But hey, It's the Sound of Freedom.

That is on take off? What about landing? F-16's have a reasonable soundlevel on landing, how does an F-35 compare to that?

They had one at a airshow last summer. It wasnt part of the airshow, it was just taking off and leaving for more testing. It was the loudest fucking thing I have ever heard. It was so loud I could feel it in my whole body. Pretty amazing

Documenting risks to the F-35's Autonomic Logistics Information System, which Department of Defense officials have described as the "brains" of the fifth-generation fighter, an April 14 Government Accountability Office report says a failure "could take the entire fleet offline," in part, due to the lack of a backup system.

While the single seat F-35 Joint Strike Fighter can still technically fly without this software system working at full capacity, both the GAO and military officials agree that it is critical to the program's overall success and long-term sustainability.

The closest thing I've heard to noise that thing makes at takeoff is a B-1 taking off at max weight. It's way louder at takeoff than an F-16.
A normal landing is about the same as an F-16.

In terms of dB, it is hard to distinguish it from an F-18. Data from Eglin AFB is publicly available. Despite all the data, though, it is hard to find identical passes by different aircraft at equivalent power settings.

Which has absolutely nothing to do with this thread.

You haven't quite lived until you've been on the mast of a CVN when they decide to do high power turns on the flight deck. Oh dear god I was not happy. That shit literally makes your insides rattle, and that was from several hundred feet away.

the f-135 engine is very powerful, and therefore very loud.
even a mil power takeoff puts out a lot of noise.

Hmmmm great!

Witnessed a B-1 during a flyby at an airshow many years ago.

B-1 passed slowly first, followed by a B-52.

Everyone was watching the B-52 climbing away from the airfield while the B-1 made a sneaky turn, lit all four afterburners and came in low and very fast.

Luckily I had hearing protection, people who didn't, almost hit the deck by fear.

I see and hear them almost daily and can watch them from my back yard. They are a bit louder but nothing out of the ordinary to me. Of course, I've been hearing AV-8's for years now too.

Yes, they are loud. Now, the first post may be a bit of an exaggeration (I can carry on a conversation just find at the end of the VPS terminal building, but there is a marked difference between the 35s and 15/16s. They also project sounds over very long distances. Particularly at night we can easily hear them headed offshore for testing. It's not terribly uncommon for my house to get overflown at low altitude as they return to Eglin. They are loud and easily distinguishable from other jets.

I work with F-35 and F-18's. The 35's are MUCH louder than the 18's. Double earpro loud.

I can tell when the f-35s are taking off vs f-16s and I live about 12 miles away.

This is dB vs slant range. The chart is a mess, even after I tried cleaning up overlapping data labels

Sorting by throttle setting and airspeed would be the next step, but you'd have to know whether each particular aircraft uses ETR, PLA, etc.

One aircraft is consistently louder than the others ... and it's not the F-35.

Fighter aircraft are unapologetic when converting dinosaurs to noise.

They airport I'm based at and the Lockheed plant are close to one another.

I see F-35s all the time.

Very loud and fun to watch.

I was visiting down there this summer and managed to sit up on the hill a while on the west side by the plant and watch a couple of them takeoff and land. They are stupid loud. But so freaking cool. Its like watching my money fly by.

I live 3 miles off the NW end of the main runway at Davis Montham, directly along the centerline.

Can't wait until they get their F35s

43,000 pounds of thrust in full afterburner. 28,000 pound in full military power. That's getting close to twice the thrust of an F-16 and obviously close to twice the noise in full afterburner and the same levels of thrust and noise of an F-16 in full afterburner while the F-35 is only at full military power.
