What's the loudest GA aeroplane out there?

[Antsl]

The Piaggio P.180 Avanti ... that gets me out of the house looking!

This was an interesting watch - so loud it made ground crew sick

Anything with a Garret. Cessna A37 Dragonfly, Any bloody Queenair owned by Codds. Just reading this brought back memories of the bellow coming from those things at takeoff power.

Oh I dunno. I found that particular sound to be quite nice! Almost as good as a Titan at T/O power.

Loved the sound of a certain Queenair going overhead my Unit in YPLC back in the late 90's at 0 dark hundred! Flown by a certain SMS777.

And Pinky their idea of fly neighbourly for the good citizens of North Shields was to give them a serve on the way in by landing on 01 and follow up half an hour later with a second dose by invariably departing on 19 at Port Lincoln.

I remember that! Never used to bother me either!

[Checkboard]

all civilian "aircraft operation other than a commercial aircraft operation

So flying Instruction or Charter isn't GA??

[zanthrus]

I wonder if a Saturn V going to the Moon would be considered a very expensive GA Charter? Certainly not RPT! NASA is a civilian agency. 🤣

Correct. Flying instruction is "Commercial Aviation". Once the pupil pilot is licensed and fly's by him/her/itself, it is categorised as GA or "Private Aviation" Funny that. Not that any authority is itemising that..oh yes, in India it is definitely itemised. In Germany, it is classified as "Sport Aviation", (crude translation). "Sport Aviation" is of course taxed accordingly..

Perception is everything!. The Piaggio is not particularly loud, but the sound may be irritating. You may find your neighbour's lawnmower "loud" but it may not be loud on the decibel scale. Frequency and pitch (low-high) of the sound is a perceptual determinant . The sound may be just an annoyance to the human ear, particularly at a certain place and time. Loudness is pure decibels. A Rolls-Royce Dart engine operating at a certain RPM with a certain propeller combination is "loud". Damaging to the human ear actually. Three P&W JT8D turbojets on a corporate B727-100 at MTO on a -30C morning is loud. Been there..I luv it! May not have been GA..

[SASless]

Hands down.....this old girl on full afterburners wins the noise making contest!

In Australia General Aviation is defined as non-scheduled flying so GA includes commercial ops like charter, survey, air-ambulance, rescue, firefighting. instruction etc. Other parts of the world may differ.

What a useless video. No sound at all from the aircraft in question.

[deja vu]

Before Garretts there were Astazous, fitted to all sorts, Skyvan. Jetstream, Mu2's, etc.
Apparently decibels to hp ratio a clear winner

Titan at T/O power had a lovely mellow note,
unlike the augmenter tubes on a Queen-Air which can only be described as a bellow.

Of course the mighty Bou was no quiet puppy-

Remember reading in Business & Commercial Aviation over 30 years ago that the flyover noise level of a Queenair at 5,000' was louder than a 707 at the same altitude..! Was loud enough on the inside as my deteriorating hearing is proof of after 3 years in the NSW Air Ambulance, many noise complaints with our back of the clock departures from Mascot, people complaining of "noisy military aircraft"!

[Ixixly]

The Islander is the worst and if you think otherwise then clearly you've had your brains rattled around more than an Islander driver has
