Piper's Aztec line of piston twins are big, trucky workhorses well known for their ability to lift heavy loads out of short runways. They also have remarkably docile handling characteristics and cabin volumes reminiscent of those huge 1950s-era General Motors land yachts. At 7,000 feet, early normally aspirated Aztecs with standard fuel tanks can cruise as fast as 180 kt/208 mph and fly as far as 780 nm/900 sm. Expect fuel burns for this 75-percent-cruise situation to total approximately 27 gph. Turbocharged models, of course, can fly faster and, if they are equipped with optional fuel tanks, farther.
