One of the primary benefits of the Warbird operations is that you don't have to have a full-blown CASA AOC with Chief Pilot, massive operations manuals and reams of paperwork costing many thousands of dollars and great effort. With the Warbird category practically any CPL can apply for an Warbird AOC equivalent and start flying. Great for one-man operations / as a hobby etc.
And then there's the downside - no Act Liability insurance coverage to fall back on if no insurance available due to breach of policy conditions by rogue operator .......
