European Noise Restrictions

[Cyril Gibb]

We were in Kufstein Austria yesterday and there was an incredibly quiet single flying around.  It couldn't have been electric because a short while later it was towing a glider.  What does a Mooney require to meet noise regs?  Does it cost much engine power?  Does it significantly affect cockpit noise levels?

[Guillaume]

There is no european noise restrictions as such. It varies from country to country. However we do have european noise certificate.

Most noise restrictions are in Germany / Austria where usually a quiet aircraft get a cheap landing fee. A noisy aircraft is going to get an expensive landing fee.

In France we have some restrictions at few airfields for noise abatment purposes (ie no VFR traffic pattern during the weekend, airport  closes between 2300 and 0600 local...) 

You obviously can't change the way a Mooney operates (as it was certificated with POH data) so there is no actual change in power / noise level.

On a Mooney, the only way to improve the noise level is by changing the prop (per STC). On the M20J, the mt-prop with new blades is supposed to give you better or equal performance.
That's why you find a lot of Mooney in Germany with a mt-propeller.

Is there a noise certificate for an Ovation 2?

Pieter,

See if this gets you closer...

http://www.mt-propellerusa.com/en/mtusa/stcs/mooney_8.htm

It comes from the MT US site...

But if it gets you close enough. For contacts or other details....

Best regards,

Yes, because the Ovation 2 (280 hp) is EASA certified.

If your aircraft is EASA registered, you should contact your local CAA to get a noise certificate.
If it's N-reg, check this.

And beware, every airfield in Europe does have the freedom to do their landing fee schemes by themselves. It is most common in Europe now to not accept any noise certificate if you are flying on N-reg - bad trap !

The plane might have been a microlight. They have a lot stricter noise limits then "classic" planes.

Also planes from flight schools tend to use all kind of noise reduction, because on many fields they are otherwise very restricted on flying circuits.

For an N-Reg you (like yours) can design your own noise cert based on FAA template and EASA database information.
You have to verify S/N and prop based on the EASA Database..
I will enclose the EASA doc and my as template:
TCDSN EASA.IM_.A.266 Issue 2.pdfN913KSNoiseCertification.pdf
