Challenger 605

The Challenger 605 retains the roomy interior of the previous entries in the Challenger 600 line, and is designed to provide all the amenities needed for a comfortable journey. The cabin measures 6 feet high, over 7 feet wide, and 28.3 feet long, with a total volume of 1,146 cubic feet—more than enough room for passengers to move about and stretch their legs on the long, international flights the 605 is capable of handling. With 115 cubic feet of internal storage, they’ll also be able to conveniently access their luggage in flight.

Bombardier solicited customer feedback in their cabin redesign of the 605, and also incorporated lessons learned from the development of their large-cabin Global 5000. The interior has been fitted with additional LED lighting, as well as larger, higher-positioned windows. It also boasts an improved galley, more ergonomic lavatory, Ethernet-based management system, larger video monitors, and sturdier work tables, so those aboard can stay productive or entertained on extended trips.

The Challenger 605 is powered by twin General Electric CF34-3B engines, each producing 8,729 lbs of thrust. These engines give the 605 a range of over 4,000 nautical miles under NBAA IFR with four passengers, and power it to a high-cruise speed of 540 mph. Improvements have also allowed the jet to be more cost- and fuel-efficient, burning about 258 gallons of fuel per hour.

Another feature retained from the 604 is the super-critical wing design, which allows for increased speed and stability during flight. The 605 features a 5,015-lb. payload, an increase of 200 lbs. over its predecessor. Bombardier also repositioned the jet’s fuel tanks, added an aft bladder tank, and upgraded the tailcone tank, aiding with weight distribution and fuel consumption.

Bombardier upgraded the 604’s avionics system, replacing it with the more advanced and easy-to-use Rockwell Collins Pro Line 21 suite. The new system has 55 percent more viewing area on its four-screen display, and utilizes fewer control panels and less weight. CNS radios, Honeywell Laseref V IRS systems, and an improved Digital Air Data Computer are also included.
