 Compared to the CL-215, the CL-415 has increased operating weight and speed, yielding improved productivity and performance.Due to the increased power of its pair of Pratt & Whitney Canada PW123AF turboprop engines, each capable of generating up to 1,775kw of thrust, these are located closer to the fuselage in comparison to the CL-215's arrangement.While this repositioning would typically reduce lateral stability on its own, this is rectified via the addition of an inverted fixed leading edge slat forward of the righthand horizontal stabiliser.
