I have often wondered if I can bring my own parachute on board as part of the carry-on. One never knows; I may have to leave a flight early.
To my surprise, the FAQ of Ryanair address this question:
CAN I BRING A PARACHUTE?
Parachutes of any type, recreational or sports type or paragliding wings (also known as ‘canopy’) can be accepted for carriage as checked-in or carry-on baggage subject to the standard restrictions for size and weight. These packs may contain an auxiliary or emergency ‘chute’ and a barometric mechanical activating (auto-release) device. These accessories are acceptable for check-in.
The parachute pack must not contain pyrotechnics or smoke canisters- these accessories are not acceptable for carriage on our aircraft.
They also allow self-inflating life jackets and an avalanche rescue pack, although all three of these gimmicks combined would probably exceed the 10 kg allowed in total.
On my next flight, I’ll be prepared.
