The aim of the game Ladies and Gents is to fly as little as possible for as much money as you can.
GG, couldn't agree more with that.
Since the question was for driving a 210 or similar up north we should consider that the drivers can be either casual or fulltime. It's been a while since I sat down and worked out the break even point, but I seem to recall it was around 550hrs a year.
So, basically if your fulltime, try and fly less than 550hrs a year. Casual, try and fly more than that.
Happy to be corrected on those numbers. Maths never was a strong suit of mine.
Sorry about the drift, back to the scheduled programming.
