By the time it is outfitted, you have a $1.5M+ aircraft with two pilots and a usable load of only 2 to 3 people and a couple hours of gas. Add that to a westerly track in the middle of winter and you are going nowhere fast. After 25 hours or more of proving and validation flights in addition to pilot training and proficiency checks (no simulator school in works yet either), you are in an awfully deep hole and the average "day" trip in the "dayjet" will only bring in an average of $5500.00 in revenue (4-5 hrs @ 1200 to 1500 per hour). Competing against other charter outfits in roomier cabin turbo-props that will carry all these "daytripper's" crap and only take 30 minutes (at most) longer on the same trip...NO CONTEST! You would have to sell it at a lower price point and get the volume. Then you are doing a 100 hour every month and factoring that down-time into your monthly revenue potential.
Just a little business 101 for the interested.
I do wish them luck. Neat idea, however, tough to compete with the Pilatus like some have noted flying @ 265 kIAS carrying 3300#'s useful and a cabin larger than the BE20.
