Record number: 2, Textual support number: 1 OBS
The aircraft classification number is calculated with respect to the center of gravity (CG) position which yields the critical loading on the critical gear. Normally the aftmost CG position appropriate to the maximum gross apron (ramp) mass is used to calculate the ACN. In exceptional cases the forwardmost CG position may result in the nose gear loading being more critical. 2, record 2, English, - aircraft%20classification%20number
Record number: 2, Textual support number: 2 OBS
ACNs are expressed on a scale from approximately 5 (least demanding aircraft) to 110 (most demanding aircraft). ACNs are applicable only to aircraft having an apron (ramp) mass equal to or greater than 12 600 lb. ACNs have been assigned to present-day aircraft at their maximum and minimum operating masses/weights and at a specific tire pressure. The ACN should not exceed the pavement classification number (PCN) for unrestricted aircraft operations. The ICAO ACN system is the internationally approved and accepted method for ranking aircraft in terms of their pavement-strength requirements. 3, record 2, English, - aircraft%20classification%20number

Le numéro de classification d'aéronef est calculé en fonction de la position du centre de gravité qui fait porter la charge critique sur l'atterrisseur critique. On utilise normalement, pour calculer l'ACN, le centrage extrême arrière correspondant à la masse maximale brute sur l'aire de trafic. Dans des cas exceptionnels, le centrage extrême avant peut avoir pour effet que la charge appliquée sur l'atterrisseur avant sera plus critique. 2, record 2, French, - num%C3%A9ro%20de%20classification%20d%27a%C3%A9ronef

Les ACN sont exprimés selon une échelle allant de 5 environ (pour les aéronefs les moins lourds) à 110 (pour les aéronefs les plus lourds). Les ACN ne s'appliquent que dans le cas d'aéronefs ayant une masse sur l'aire de trafic supérieure ou égale à 12 600 lb. Des ACN ont été attribués aux aéronefs actuels pour une masse maximale et minimale d'exploitation et une pression des pneus précise. L'ACN ne devrait pas être supérieur au numéro de classification de chaussée (PCN) dans le cas de chaussées pouvant être utilisées sans restriction.

The molecules of commercial polymers do not have a single molecular mass; the molecular mass distribution follows statistical considerations.

According to the Oxford English Dictionary and the Webster Third New International Dictionary of the English Language "radiocarbon" refers to any radioactive isotope of carbon and hence has a more general sense than "carbon-14". They point out, however, that "radiocarbon" refers specifically to the carbon-14 isotope. All the other sources consulted do not make that distinction and give those terms as perfect synonyms, which, we feel, reflects the current usage. 8, record 8, English, - carbon%2D14
