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 definition 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 set brochures and marketing reasons.

Aeronavtika - Standardizirani podatki o masi potniških sedežev

Masa opreme v potniški kabini je pomembna tema v aeronavtiki. Masa opreme v potniški kabini ima neposreden vpliv na koristni tovor letala, obratovalne stroške in prihodke letalskih družb. Zaradi števila sedežev na letalih so ti eden najtežjih delov opreme v potniški kabini. Trenutno je precej mas sedežev uporabljenih brez kakršne koli jasne definicije, npr. največja dovoljena masa, certificirana masa, določena masa. Za opredelitev vsake definicije potniške kabine glede na potnike je potrebno pridobiti primerljive mase sedežev. Sedeži na letalih se zelo razlikujejo glede mer in vgrajenih funkcij ter možnosti. Za izračun mase in primerjavo izdelkov so zelo koristne informacije o primerljivih masah, ki temeljijo na standardnih masah.
Cilj tega standarda je določiti jasno definicijo za različne informacije o masi in osnovo za izračun mase sedeža za pridobitev primerljivih mas sedežev za brošure in trženje.
