You all seem to be focusing on a bit of flight planning and getting a pilot to fly it. That's the easy bit. It's the maintenance planning and asset management part that is critical.....and then of course it's about the safe operation of the aircraft. That goes well beyond the ability to match the amount take offs to landings. If you have the operating pilot doing all the ops as well, such as flight planning, slots, handling, onward surface transport etc...the safety is compromised. The incident in Egelsbach in the Citation X is testament to that.
Financially, operationally and safety wise there is a much bigger picture to deal with in order for the aircraft to be operated efficiently. It requires expertise and experience that no single person has, but many organisations do. If the aircraft goes on an AOC, you can tap into that expertise. (or reputable management companies of course). It's up to the owner to ensure he picks the right partner, as in any business deal. The ability to offset some of the costs and make it a more financially viable proposition can also be achieved by chartering the aircraft out if you take an AOC operator. Check though that the AOC company has the commercial nous and track record to support their claim.
