The units of measurement used in this document are in accordance with the International System of Units (SI) specified in Annex 5 to the Convention on International Civil Aviation. Non-SI units are shown in parentheses following the base units. Where two sets of units are quoted, it should not be assumed that the pairs of values are equal and interchangeable. It may be inferred, however, that an equivalent level of safety is achieved when either set of units is used exclusively.

The format of this document has been adjusted to make it user-friendly and for reference purposes. Any comments should be sent to erules [at] easa.europa.eu (erules[at]easa[dot]europa[dot]eu).
