There is no standard aircraft utilized in medEvac operations. Airplanes (fixed-wing aircraft) vary in size from single-engine turboprops such as the Pilatius PC-12 to twin-engine aircraft like the Cessna Citation, Beech B-200, and Lear 35. Most are either turboprop or jet aircraft which lends to faster, more versatile performance.
