The second engine gives you redundancy, but it also offers an abundance of power for takeoff, something that translates directly into rate of climb. On our test hop, we were seeing better than 1,500 fpm at cruise climb up through 7,000 feet and around 800 fpm up to 9,500 feet. The company advertises a maximum climb of around 1,700 fpm at maximum takeoff weight. Even with one engine caged, we were still seeing around 150 fpm at 9,000 feet, though we were light, at around 5,000 pounds, with only two aboard and a little more than half tanks. At sea level and maximum takeoff weight, the airplane's maximum single-engine climb is an impressive 390 fpm. I've flown singles that can't do that.
