Colibri Aero and J&C Aero have developed cargo containers for wide-body passenger cabins that allow Airbus and Boeing cabin conversion between passenger and cargo operations within just 24 hours. Available in five different sizes, the cargo containers are designed for wide-body passenger cabins of Airbus A330, A340 and Boeing 767, 777. Each is equipped with its own smoke detector and intended to temporarily replace passenger seats. The initial modification is intended for use in cabins with the supervising cabin crew members. After certifying the containers under European Union Aviation Safety Agency STC requirements, the modification will be upgraded for other aircraft types and size variations. With one container being able to transport up to 850 kg of commercial cargo, a typical Airbus A330 cabin can be converted in just 24 hours fitting 36 containers, meaning almost 27 tonnes of cargo per single flight can be transported inside the passenger cabin.
