Well, the “too noisy” argument is usually brought up by the usual suspects – green-minded opinion makers who would happily see General Aviation banned altogether. That kind of narrative sells well in Germany and Switzerland.
But there’s another layer: the Avanti is an Italian aircraft competing in an American market. Faster than a King Air, less fuel, jet-like comfort, and built outside Wichita – not exactly what the big US manufacturers wanted to see.
So, the “noise” label was a convenient stick to beat it with. Ironically, inside the cabin it is remarkably quiet, much more pleasant than many turboprops of the same class.
In other words: part politics, part economics, part myth. The Avanti became a scapegoat – just like the Mitsubishi MU-2 before it.
GA / Small Business Aircraft Noise Comparison (approximate)
Aircraft External Take-off (dB(A)) Cabin Noise Cruise (dB(A)) Comments / Subjective
Piaggio P.180 Avanti II 79–80 68 High-frequency sound, cabin surprisingly quiet
Beechcraft King Air 200/350 78–79 72–75 Classic turboprop sound, more droning inside
Mitsubishi MU-2B-60 81–82 74–76 Loud, high-speed prop; reputation partly due to US safety regs
Fairchild Swearingen Metro III 82–83 75–77 Narrow, droning cabin; louder inside than Avanti
Pilatus PC-12 NG 77–78 70–72 Quiet, smooth turboprop; good cabin comfort
Learjet 35 83–85 75–78 Clearly louder; EU operation only with hushkits
Dassault Falcon 20 (early) 84–86 78–80 Loud early jet; characteristic scream
Cirrus Vision Jet SF50 (1st series) 79–81 80–85 Cabin very loud, Gehörschutz recommended; Collier Trophy
Cirrus Vision Jet G2 79–80 70–72 Much improved insulation, comfortable cabin
So, in numbers, the Avanti is not louder than a King Air or Metro – actually a bit less.
The real difference is in the sound character: the Avanti’s higher frequencies make it seem harsher, while the Learjet 35 is, in fact, clearly louder overall.The Learjet 35 is still flown in Europe, but only with hushkits to meet EU Chapter 3 noise standards. Some airports with strict local limits may still restrict it. The Mitsubishi MU-2, on the other hand, never had EU noise restrictions, although it carries a certain “reputation” due to US safety regulations (SFAR 108), not noise.
This nicely complements the noise comparison: the Avanti, King Air, or MU-2 are quieter in practice than many small jets, even if the Avanti’s high-frequency sound makes it feel louder.
