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.

You had headsets? Lucky baastard! :{

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

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! :DNever used to bother me either!

So flying Instruction or Charter isn't GA??

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..

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.

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"!

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 :}

Just been reminded how noisy the Dauphin is when it's heading towards you - you can hear it for miles but once past it's quiet... could hear that one from at least 15 miles away...

Edit: didn't hear him for quite so long on his return, but there was a hill in the way! Conversely, the delightful DH-90 Dragonfly that followed him out of Biggin Hill and passed about a mile south of me wasn't nearly noisy enough - I love the sound of Gipsy Majors in the morning!

Except the Lightning had Avon engines. Just as noisy though!

I agree that the Bongo is by far the worst GA transport for its occupants. Enough to make one’s ears bleed. Anything with Garretts is only as good as the internal soundproofing and engine location relative to the cockpit, which varies between airframe types - eg Conquest not too bad on the inside, but still noisy enough that too much exposure could damage hearing on the ramp.
Not GA, but anything with RR Darts made quite a nasty racket, too.

HS125-600 with RR Vipers pumped out a few decibels.

Whereas the later model HS125's, it was the APU that was effing noisy!

Yeah I remember those and they didn't climb away real fast from over the houses. The outfit was run by a guy called Smith from Tassie I think and he had a young Italian pilot working for him as well.

Any Cessna 188 with the prop ‘tweaked’ especially on a calm cool morning with an inversion, full can and an ROC of less than 100 fpm. Ground level being service ceiling when the pilot is ‘hungry’ and the cockies are desperate.

Avanti for props.

There used to be one in Australia…. but I haven’t heard it for a while! :}

I used to fly this machine, a Lockheed 10A. It was pretty loud and would attract the odd phone call complaint to ATC.

Early Lears (23-25). Shook the bloody ground like a junior F-4 in burner.
I fly a bunch of loud stuff, but bow to Uncle Bill’s auditory mastery...

Why did the Dart make more noise in the Hawker Siddeley H.S. 748 (RAAF) that in the F27?
The bl00dy 748 would wake up all of Amberley at 2am.

The MU2, Turbo Comm and possible the Conquest are noisy on the ground.
The C185 and Queenlier noisy on take off and airborne.

I’ll second LearJet, the original and add JetCommander to the list for the same CJ6 noise. Lovely 👌🏼

A Cirrus SR-22.

601, the 748s of 34 Sqn were fitted with Rover APUs which were not only loud but broke all physics laws by getting louder as you got further away. Don't know about the SAN 748s That may account for the loss of sleep.

Oh, I dunno about that one Clare.:hmm:


Admittedly I have only a grand total of 3 hours ICUS on type. (P2-DNN langtaimbak:sad: with Luk V as checkie)
