Aerospace series - Rotorcraft constant wear lifejackets - Requirements, testing and marking

This document specifies requirements for constant wear lifejackets for use by helicopter crew members and passengers in the event of a ditching or water impact, to ensure minimum levels of performance. It only applies to constant wear lifejackets for use by adults and that are intended to be manually inflated after leaving the helicopter.
Helicopter constant wear lifejackets are sometimes designed to be worn with or without a helicopter immersion suit and/or emergency breathing system.

Série aérospatiale - Gilets de sauvetage de port permanent de giravion - Exigences, essais et marquage

Le présent document spécifie les exigences relatives aux gilets de sauvetage de port constant destinés à être utilisés par les membres d'équipage et par les passagers des hélicoptères en cas d'amerrissage forcé ou d'impact avec un plan d'eau, afin de garantir des niveaux minimaux de performance. Il s'applique uniquement aux gilets de sauvetage de port constant destinés à être utilisés par des adultes et conçus pour être gonflés manuellement à la sortie de l'hélicoptère.
Les gilets de sauvetage de port constant pour hélicoptères sont parfois conçus pour être portés avec ou sans combinaison de protection thermique en cas d'immersion d'hélicoptère et/ou système de ventilation d'urgence.

Aeronavtika - Stalno nošeni rešilni jopiči v rotoplanih - Zahteve, preskušanje in označevanje

Ta dokument določa zahteve za stalno nošene reševalne jopiče, ki jih uporabljajo helikopterske posadke in potniki v primeru pristanka v sili ali vdora vode, da se zagotovi minimalna raven zahtevanih lastnosti. Uporablja se samo za stalno nošene reševalne jopiče za odrasle, ki jih je treba ročno napihniti, ko oseba zapusti helikopter.
Stalno nošeni rešilni jopiči v helikopterjih so zasnovani za uporabo s potopno obleko ali brez nje in/ali sistemom prezračevanja v sili.
