Commission Directive (EU) 2015/996 of 19 May 2015 establishing common noise assessment methods according to Directive 2002/49/EC of the European Parliament and of the Council (Text with EEA relevance)
When the UK left the EU, legislation.gov.uk published EU legislation that had been published by the EU up to IP completion day (31 December 2020 11.00 p.m.). On legislation.gov.uk, these items of legislation are kept up-to-date with any amendments made by the UK since then.
Legislation.gov.uk publishes the UK version. EUR-Lex publishes the EU version. The EU Exit Web Archive holds a snapshot of EUR-Lex’s version from IP completion day (31 December 2020 11.00 p.m.).
EU Directives are published on this site to aid cross referencing from UK legislation. Since IP completion day (31 December 2020 11.00 p.m.) no amendments have been applied to this version.
Data is provided for three helicopter classes, based on maximum take-off mass:
Light helicopter (LHEL) MTOM < 3 000 kg
Medium helicopter (MHEL) 3 000 kg < MTOM < 6 000 kg
Heavy helicopter (THEL) MTOM > 6 000 kg
Default arrival and departure flight profiles are provided as fixed point profiles. Default departure flight profiles assume climb to a level flight altitude of 1 000 ft (305 m) for each helicopter class. Where the level flight portion on departure or arrival differs locally from these values, it is recommended that the default profiles are adapted to reflect local circumstances.
