This is the noise certificate listing referred to by @Maoraigh earlier:
(a PDF can now be dropped into the forum, same as images have been able to)
A friend of mine had a long discussion about noise certificates at an airport in south Germany. Since he was flying with a Swiss registered airplane he didn’t have the German noise certificate however he had one from Switzerland. As discussed before they calculate if you are in the “erhoehter Laermschutz” category from LLV
and they had a neat Excel sheet to do so which he could get a hold of (The Excel sheet was created by the noise abatement officer of the district government of Duesseldorf). I successfully used this Excel sheet in the past to claim “erhoehter Laermschutz” at airports in Germany.
Usually yes, but not during the Aero, since they have flat fees for the event, irrespective of noise class. Probably because they don’t want to lose time messing around with these things during the show.
Generally speaking, if you do have a (proper) noise certificate, then yes, you should show it by your own initiative. The reason is that some Flugleiters/admin staff are lazy, and particularly when they see that a foreigner is coming up to pay, they will not by their initiative ask for the certificate, and simply charge you the very worst (highest) noise category, thinking that the foreign pilot doesn’t know all these details anyway. Again, not always, but it happened to me several times.
This has come up before… does Friedrichshafen EDNY want to see a noise certificate?
If you have one, you can ask them if they want to see it or you can leave it at that.

So with a foreign reg aeroplane, is it worth being pre-emptive and presenting a noise cert in Switzerland/Germany, or wait to be asked?

Flew to Switzerland last month. I wasnt asked for a noise certificate, should I have offered one, and if so would I have got a better deal landing fee?
The only thing they really asked was if my partner was a pilot, if so, we would not have been charged a pax fee (10Euro)

The ICAO noise test procedures (in ICAO Annex 16 vol 1) have changed over time, which may have something to do with it. Aircraft that were first type certified before 1988 were tested to chapter 6 and later aircraft to chapter 10. The chapter 6 test involved flying at max cruise power, level flight at a height of 300m above the noise meter. The later test simulates a take off scenario with the sensor on the extended centre-line and the aircraft climbing out at Vy. This later test also provides for various corrections to the result depending on different factors.

The motivation was that ICAO standards don’t provide for noise certificates for that aircraft anymore. (It is a 1979 PA-28-181.)
That is probably correct. Looked a bit more into this, and there must have been some gradual change in where the noise standards are defined or something. From ICAO to EASA or some other bureau ? Newer planes do not have the same noise certificate, and for older planes it depends on age and when the local type certificate was obtained. It’s very weird the whole thing, and not easy to see the logic, if any ?
LT (Luftfartstilynet) only have this very old regulation. As you can see, if the plane MTOW < 5700 kg AND it received it’s type certificate (In Norway) before 01.01.1975 OR is a amateur built plane, then it must have a noise certificate. But there is also exceptions. If the airplane has been continuously on Norwegian register since before 01.01.1994, no noise certificate is needed, regardless of age.
Maybe there is something similar in Sweden. In any case, the only “new” airplanes (SEP < 5700 kg newer than 1975) needing noise certificate today are amateur built aircraft. They need to be measured after this ancient ICAO standard.
I don’t know what has happened. Maybe the noise has been moved from ICAO to EASA, or it has been moved to some unrelated (for aviation) environmental bureau, local or not.
