the 60 and the 45 are great aircraft, I fly the 60 and you will love it, get the good brakes and donīt worry about runway length, it will stop you real hard. The 45 is new bombardier design, different philosophy but also will do the job, cabin is narrower then the 60 pax are more comfortable on the 60 and if you can get it without divan much better. Fuel flow on the 60 is 1250lbs/hour
Yesterday I did a medium flight, 7.800lbs full, 4 hours flight and I had 2.800 left when landed flying at FL390 ISA+8 M.78-.80, those are real figures
