Do planes carry spare lifejackets?

[TightSlot]

If it helps...

• Yes, spare lifejackets are carried, and checked by the cabin crew as being present as part of the pre-flight equipment checks. Serviceability/Time expiry are checked by engineers periodically, as required.
• Many aircraft do not have slide rafts at each door. The ditching procedures require some pax to swim to slide rafts or to wait on the wing until rescued or transferred to a slide raft.
• Some aircraft carry additional rafts as part of their EROPS equipment
• Wearing a lifejacket will preserve an unconscious survivor upright and above water level. A conscious survivor will be supported and have access to the light & whistle. Treading water for an extended period without a lifejacket is surprisingly tiring.
• A yellow lifejacket is more visible than some dark clothing
