What's the loudest GA aeroplane out there?

[treadigraph]

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!

They were sensitive neighbours way back in the 70's and quick to complain - and it hasn't stopped.

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.

[There was another model QueenAir that had a flat 8 from memory (need to search the old log books]

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.

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.

[RENURPP]

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

[Switchbait]

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

[runway16]

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.


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