Mike Summey, Owner/Chief Pilot, King Air E90
The best performance after adding the new Blackhawk [upgrade] was at FL230 where I saw 278 knots with a fuel burn of 590 pounds per hour. Do the math! More speed and less fuel per mile flown. That’s a hard combination to beat. Oh! It only took 12 minutes to climb to FL230 with the main tanks full and four people on board. I’ve seen the promotional literature Blackhawk puts out, but my E90 beats any numbers I’ve seen.
