The Bombardier Challenger 605 is a large-cabin business jet introduced in 2006 as an upgraded successor to the Challenger 604. Built on the proven Challenger 600 platform, the 605 retained the aircraft’s core performance capabilities while incorporating modern avionics, structural refinements, and an updated cabin environment to meet evolving operator demands. Deliveries began in 2007, and the type remained in production until 2016, when it was replaced by the Challenger 650.
The aircraft is powered by two General Electric CF34-3B engines, each rated at 9,220 pounds of thrust, providing a maximum takeoff weight (MTOW) of 48,200 pounds. With a balanced field length of approximately 5,950 feet, the Challenger 605 can operate efficiently from a wide range of airports. It offers a maximum range of 4,000 nautical miles, enabling nonstop flights such as New York to London or Geneva to Dubai.
Inside, the Challenger 605 features cabin enhancements compared to its predecessor, including larger windows, improved lighting, and reconfigured storage options. The cabin accommodates up to 12 passengers in a typical business layout, offering a flat-floor design with flexible seating arrangements, conference groupings, and divan options for long-haul comfort.
The 605’s flight deck introduced the Rockwell Collins Pro Line 21 avionics suite, replacing the earlier system used in the 604. This modernization improved situational awareness, integration, and operational efficiency, aligning the Challenger with new-generation standards in its class. The aircraft’s combination of range, comfort, and updated systems has kept it a competitive choice in the large-cabin segment, with many still active in fleets worldwide.
