IO540, much truth in what you say. Undoubtedly if the revenue potential for this feature from our private customers was of interest, then we would have put more energy into battling the politics. With limited resources, all our development effort goes into the airline and corporate markets where we are beginning to establish a good reputation for smart solutions. It's a real shame we can't be more responsive to our GA customers but most wouldn't argue the strategic necessity of our commercial focus.
