DACAPO^®(Distributed Autonomous CAbin POwer) follows the idea to separate the A/C into cabin systems and aircraft systems with independent power networks. Cabin systems are supplied by one or more MAGIC^®(Modular Autonomous Galley with Integrated power Cell)galleys. Interconnected MAGIC^® galleys are building-up a redundant and reliable power grid. Further aircraft systems including emergency power systems may be supplied optionally.
