Aerospace series - Standardized passenger seat weight information

The weight for cabin equipment is an important topic in the aviation business. The cabin equipment weight has a direct impact on the payload of the aircraft, operation cost and revenue of the airlines. Due to the number of aircraft seats, seats are one of the major weight drivers in the cabin. At this time, a lot of seat weights are used without any clear definition, e.g. allowable max. weight, certified weight, defined weight. For the definition of each customer specific cabin, it is important to get comparable seat weights. Aircraft seats are very different with regard to seat envelope dimensions and integrated features and options. For a weight calculation and product comparison, it is very helpful to get comparable weight information based on a standard weight.
The aim of this European Standard is to define a clear definition for the different weight information and a baseline for a seat weight calculation to get comparable seat weights for seat brochures and marketing reasons.

Luft- und Raumfahrt - Standardisierte Sitzgewichtsangaben für Passagiersitze

Das Gewicht der Kabinenausrüstung ist ein wichtiges Thema im Luftfahrtgeschäft. Das Gewicht der Kabinenausrüstung hat einen direkten Einfluss auf die Nutzlast des Flugzeugs, die Betriebskosten und die Einnahmen der Fluglinien. Aufgrund der Anzahl von Luftfahrzeugsitzen sind Sitze einer der wichtigsten Gewichtseinflussfaktoren in der Kabine. Zu diesem Zeitpunkt werden viele Sitzgewichte ohne jegliche eindeutige Festlegung, z. B. zulässige maximale Gewichte, zulässige Gewichte, festgelegte Gewichte, verwendet. Für die Definition jeder passagierspezifischen Kabinenauslegung ist es wichtig, vergleichbare Sitzgewichte zu erhalten. Flugzeugsitze sind bezüglich der äußeren Abmessungen, und der integrierten Funktionen und Optionen sehr unterschiedlich. Bei eine Gewichtsberechnung und einem Vergleich der Produkte ist es sehr hilfreich, vergleichbare Angaben bezüglich der Gewichte zu erhalten, die auf einer genormten Gewichtsangabe basieren.
Das Ziel dieser Europäischen Norm besteht in der eindeutigen Festlegung der unterschiedlichen Gewichtsangaben und einer Basis zur Berechnung der Sitzgewichte, um vergleichbare Sitzgewichte für Sitzbroschüren und für Marketingzwecke zu erhalten.

Série aérospatiale - Définition standardisée du poids d’un siège passager

Le poids des équipements de cabine est un sujet important dans l’industrie aéronautique. Le poids des équipements de cabine a un impact direct sur la charge utile de l’aéronef, les coûts d’exploitation et les recettes des compagnies aériennes. En raison de leur nombre, les sièges des aéronefs sont l’un des principaux facteurs de poids dans la cabine. Actuellement de nombreux poids de siège sont en usage sans définition précise ; par exemple : poids maximal admissible, poids certifié, poids défini. Afin de déterminer la définition de cabine spécifique de chaque client, il est nécessaire d’établir des poids de siège comparables. Les sièges des aéronefs diffèrent beaucoup en fonction de leurs dimensions d’enveloppe de siège, de leurs caractéristiques intégrées et de leurs options. Pour le calcul du poids et la comparaison des produits, il est très utile de posséder des informations de poids comparables et fondées sur un poids standard.
L’objectif de la présente norme est de donner une définition claire des différentes informations relatives au poids ainsi qu’un point de comparaison pour le calcul du poids d’un siège afin de fournir des poids de siège comparables à des fins marketing ainsi que pour les plaquettes d’équipements.
