But the biggest reason I'd stay down in the mid-teens is because the Acclaim does exceptionally well there. Heading from Midland, Texas, back home to Austin on one flight, I was at 17,500 (yes, VFR and almost completely alone in my airspace there). At that altitude on that day I was seeing 222 knots true on the display with, again, right around 21 gph fuel flow at 50 degrees lean of peak. And you can do much better in terms of fuel consumption, if you're willing to slow down a bit. At 16,500 on the way out to West Texas, I pulled the power back to 26 inches and 2400 rpm and got right around 205 knots at 18 gph with a total range of better than 1,000 nm and a fuel efficiency of better than 12 nm per gallon. Try that in a Suburban. And if I'd settled for even less speed and wanted to stretch the leg out, I could have easily flown from Central Texas to Southern California nonstop with the standard 100-gallon tanks, no less. The airplane is available with 130 gallons of fuel, though it's an option that not many customers opt for.
