Aircraft Noise Quality Standards
As part of our commitment towards more environmentally friendly air travel, requirements have been put in place to ensure that an aircraft’s noise level and impacts are within acceptable limits prescribed by ICAO.
The Noise Certificate issued by CAAS is a means of documenting that your aircraft complies with the ICAO requirements. Whilst you only need to apply once during aircraft registration, a new application is required if the noise level or standard of your aircraft changes.
Go to eSOMS for the application of a Noise Certificate.
In the event eSOMS is not available, please contact us and complete the following:
1) Noise Certificate application form CAAS(AW)143
