What's the loudest GA aeroplane out there?
 

G'day again all,

Recently been very interested in Cessna 180/185 airframes with the two bladed prop, been mesmerised by how loud these things are!
Anyhow this opened up the question that I cant seem to find: what is the loudest GA aeroplane out there?


Thanks All!

Mach1

You mean in the cockpit?

Would have to be a Britten Norman Islander wouldn't it?

How about the "Paris Jet"?

You Tube

From the ground one of the noisiest piston jobs that I recall was the Pusher twin Angel.
Silence now reigns because they have all been crashed, 4 of 4. so an extinct species.
Very specific and noisy ‘signature’ and could be heard from tens of miles away, so you knew what was coming.
The one I witnessed crash at YMBA flew into the cornfield like a sailplane on final glide,... which for this a/c it was...silent after a noisy take off, so I reckon both engines had failed. RIP that crew.

Jets are different ...specifically designed to turn Avtur into decibels.
8 EE Lightnings in stream take off, ie 16 Olympus on afterburner, thundered like worlds end, the ground shook, yr body trembled like a leaf and it looked like God pulling a string of beads to heaven. Straight up until out of sight.
Brain boggling !

It’s the MU2

end of discussion.

Lightnings are not really considered "GA aeroplanes".

My nominations would include Queenair or Piaggio 166 (not the Avanti), but as the OP states a 185 with a 2-blade prop definitely gets noticed.

Dornier DO 28. End of....

Pardon! What?

A Cirrus 22!

Beechcraft Queenair, would hafta be in the running

Not an aeroplane, but a Huey can be heard 10 miles away.

There's a few RV's getting around that are a little over the top noise-wise with their muffler configurations. Not a pretty sound. Would prefer the sound of 3 blades on a Continential in an SR22 or 210.

I'm with Xeptu. I heard a Codd Air Queen Air starting its take off run at Archerfield from my home in St Johns Wood. That is about 7 miles (and with a temp inversion).

A sound that could cause fear, portend deliverance, salvation, life, or even perhaps a hot meal if you were lucky.

Queenair...

About an hour after departure I got told by ATC that he thought I must have woke up everyone in Western Sydney when I departed YSBK at 3am on a saturday morning once.

On the ground I suspect the Turbo commander and/or most turbo props with Garrett’s. However they are pretty quiet once they get going.

The QueenAir or the Aero Commander with the GTSIO640’s (I think that’s correct) would have to be right up there. Mind you I haven’t seen one of them flying for a few years now.

RENURPP.......IGSO540's. At least, that's what was in the Queenair's, the AC680FLs. and the AC680F that I flew what seems like a million years ago in GA.

DC3 but not really GA.

In the cockpit, definitely the Islander. It is said they actually use acoustic lift ;).

Anything fitted with Garrett’s.

Any Polikarpov (also not really GA)

Absofrigginlutely................ horrible, ghastly things....

1. Cessna C336/337.,
2. Cessna C205/6 with the two bladed prop,
3. Beechcraft Queenair,
4. Piaggio P166,
5. Twin Bonanza,
6. Aerocommander 560,
7. Cessna C310D with the augmentor overwing exhaust system.

Interesting topic, and ran into this in search of noise levels: https://www.faa.gov/regulations_poli...cumentID/22945
Worth noting that these are estimated noise levels instead of measured noise levels, but the document is for take off noise with presented flap settings.
You'll find the list on document AC 36-3H Including Change1

On top of the list is Concorde with 112dBA, and eg aforementioned DC-3 has 85dBA.
Cessna 185 goes with 66dBA (no mention of the prop). 150/152 is at 59dBA, and on the bottom of the list is AA-5B TIGER wtih 52dBA.
And out of sheer interest a few picks: twin comanche 70,6dBA. Navajo up to 74dBA.
The Paris is rated at 80,9dBA.

Vulcan on take off when flying on a Permit?

A BN Islander when you forget the headset.

OK so they are all gone now but the Beech Starship would have to be a candidate. Or, in current times how about the GP180.

Yeah, but only the voters in the Balmain Labor area are worth worrying about, Bags!

Think the Dornier 28D had the same engines or very similar - plus it was a very slow aeroplane. We used to get the occasional West German AF example returning from (old) South Wales to Germany routing over south London - you could hear them coming from miles away and probably 15 minutes later still hear them half way to Dover.

Noisiest thing round here now are the Spits at Biggin - I've yet to hear anyone complain!

The Cirrus is quite a noisy bugger too, not sure if it's the prop or what...

A C185 with an IO-520 running at 2825 RPM [max 3 minutes] swinging an 88 inch 2 blade prop beats them all, trust me.

Antonov AN-2 anyone?

Harvard perhaps.

The BAC-111 made a hell of a racket, but then, the VC-10 had four of those engines!

But as for GA, yes the BE65/BE80 was allowed to do night freight runs when other types were deemed too noisy!
What a joke!

For sending the Pilots deaf.....YES!!

The AC680E had these - Model: GSO-480-B1A6. I flew the others you mentioned but they weren’t nearly as loud.
The 65-B80 had IGSO-540. There was another model QueenAir that had a flat 8 from memory (need to search the old log books) it wasn’t nearly as loud.

1-11 had a pair of Speys, the VC-10 had four Conways. Noisy on the outside I'll grant you...:}

Bellanca Viking has to be up there.

I will second Piaggio 166 , extremely noisy for its size and with pusher props too?. Obviously nothing can compete with military stuff or wonderful smokey ground shaking 60s jet liners. Opposite end of scale have to be lovely puttering old DH biplane engines , part of the sounds of an English summer

Generally anything equipped with augmentors (like most Queenairs) will be noisy. 12 exhaust pipes, no mufflers, feeding straight into the augmentor tubes! What a great sound!

Parked on the ramp, the BAC-111 APU was louder than when operating...
