Bombardier Challenger 600

Variants

CL-600


CL-600: original production version, powered by Avco Lycoming ALF 502L turbofans of 7500 lbf (33.6 kN) thrust each. Built until 1990 (89 built)


CL-600S: 3 CL-600s retrofitted with the winglets introduced on the CL-601-1A. 21 aircraft purchased by the Royal Canadian Air Force, designated CC-144, CE-144, and CX-144.

CL-601


CL-601-1A: refined version including winglets to decrease drag and more powerful GE CF34-1A (66 built, including four Canadian Forces CL-144/ CC-144B)

CL-601-1A/ER: 601-1A retrofitted with an additional fuel tank in the tail

CL-601-3A: GE CF34-3A engines with a higher flat rating and a glass cockpit.
This was the first version marketed by Bombardier.

CL-601-3A/ER: 601-3A with an additional, optional fuel tank in the tail

CL-601-3R: the tail tank was made standard, CF34-3A1 Engines were introduced.

CL-604


CL-604: major upgrade of the 601 design, incorporating more advavanced GE CF34-3B engines; increased fuel capacity, including saddle tanks in the rear of the aircraft; new undercarriage for a higher takeoff and landing weight; structural improvements to wings and tail; and a new Rockwell Collins ProLine 4 avionics system.

The C-143A is a single Challenger 604 aircraft, which was acquired by the United States Coast Guard in December 2005 as its new Medium Range Command and Control Aircraft (MRC2A).

CL-604 Multi-Mission Aircraft: militarized version, developed by Field Aviation,[13] in Danish service.

The aircraft are employed on maritime patrol and search and rescue missions.

They are capable of landing on the short, rough, gravel airstrips common in the Arctic.

CL-605


CL-605: introduced in early 2006 as an avionics and structural upgrade of the 604 design. Structural improvements include larger cabin windows.

Cockpit instrumentation updated with the Collins Proline 21 avionics and "electronic flight bag" capability. It can be visually identified by a new, rounded tailcone.
CL-610


The CL-610 Challenger E was to have been a stretched version for use as a cargo aircraft by Federal Express, or alternatively, as a passenger aircraft with seating for 24 passengers.

Federal Express placed orders for 25 CL-610s, but these orders were canceled after the passage of air cargo deregulation in the U.S. in 1977.

Development was halted by Canadair in 1981 without any having been built. A few years later, a new project would develop the Canadair Regional Jet based on a stretched Challenger design.
