Aircraft Noise Certification Type

Description

Defines an Aircraft type in terms of its certificated noise level. For example, chapter '2' Aircraft are characterised by the noisier, low bypass turbofan Aircraft engines and early high bypass turbofan Aircraft. Chapter '3' Aircraft are characterised by the modern, quieter, high bypass turbofan Aircraft engines. Chapter '4' Aircraft are Aircraft which are likely to have previously been classified as chapter '3' but are deemed to have met even more stringent standards. Note: chapter '1' is not an official classification but is / was sometimes used to indicate excessively noisy (e.g. older) Aircraft, for example Concorde. Allowable values are defined in Aircraft chapter reference data table.

Allowed values

It is only the chapter number, i.e. "2", "12", that are used in this term.

Allowed values are: "2" - "13"
