The Challenger 604, a proud member of Bombardier’s esteemed family of business jets, stands as a testament to the evolution of private aviation. This remarkable aircraft, born from the original Challenger 600 series, has undergone extensive refinements and enhancements to solidify its reputation in the long-range, business jet market. Certified in 1995, the Challenger 604 embodies a harmonious blend of range, speed, sophistication, and style.

Beneath its wings, the Challenger 604 harnesses substantial power. Its two General Electric CF34-3B engines generate an impressive 8,729 pounds of thrust each. This power enables the aircraft to gracefully carry eight passengers across distances of 3,850 miles while cruising at .74 Mach. Remarkably, the Challenger 604 can even embark on journeys exceeding 4,000 nautical miles at 424 knots, a feat attributed to innovative fuel distribution and an expanded capacity of 2,460 gallons.

Stepping into the cockpit of the Challenger 604 reveals a cutting-edge glass cockpit, the Collins Pro Line 4. Six sizable 7.25-inch screens grace the pilot’s view, presenting primary flight displays, multifunction displays, and EICAS data. This avionics suite boasts an array of pilot-friendly features, including flight director and autopilot systems, HF-9000 high-frequency radios, digital air data computers, turbulence detection radar, and dual Pro Line 400 all-digital interface comm/nav/ident radios. Together, these systems contribute to a flight experience characterized by ease and comfort.

While the cabin of the Challenger 604 is reminiscent of its predecessor, the 601-3A and -3R, it exudes an air of spaciousness. Stretching 28.3 feet in length, it offers just under 17 feet of cabin space, allowing passengers to stand tall with over 8 feet in width. The cabin’s maximum capacity, accommodating up to 19 passengers, may feel crowded, but it truly shines with 10-12 passengers on board. The flexible cabin layout can be configured in a double-club or forward club/half club/divan arrangement. For intercontinental journeys, passengers can appreciate the deluxe galley and lavatory, as well as remarkably low noise levels throughout the cabin.

The Challenger 604 exemplifies Bombardier’s commitment to delivering exceptional aircraft. With its ability to effortlessly conquer long-haul missions and a range of amenities catering to both passengers and crew, it comes as no surprise that Bombardier produced a total of 347 Challenger 604s, leaving a lasting mark on the aviation landscape over a decade of production, from 1996 to 2006.

Performance-wise, the Challenger 604 excels in its range, payload, and runway capabilities. Its range, calculated with NBAA reserves and a 200 NM alternate, extends to 4,017 nautical miles. The maximum payload capacity stands at 4,815 pounds, while the aircraft can still carry a payload of 1,265 pounds when fully fueled. Takeoff performance requires 5,840 feet of runway at sea level under standard conditions, and landing distance at sea level under ISA conditions is a mere 2,358 feet.

In terms of speed, the Challenger 604 is no slouch, boasting a maximum cruise speed of 468 knots. For more extended journeys, it maintains an efficient long-range cruise speed of 436 knots. Even on shorter trips, it proves its efficiency, reaching 300 nautical miles in just 47 minutes, 600 nautical miles in 87 minutes, and 1,000 nautical miles in 139 minutes, providing versatility for various travel distances. The aircraft also ascends to a maximum certified altitude of 41,000 feet, offering superior altitude capabilities that enable smooth navigation above most weather systems and air traffic.

Understanding operating costs is crucial, and the Challenger 604 provides a cost-effective option. Variable costs, including fuel, maintenance labor, parts, maintenance programs, and miscellaneous trip expenses, amount to $5,295 per hour of operation. On the fixed cost side, annual expenses, encompassing insurance, maintenance software, miscellaneous services, modernization, training costs, facilities expenses, and personnel costs, sum up to $3,367,348 per year, accounting for the aircraft’s hours flown.

In summary, the Challenger 604 is a remarkable testament to Bombardier’s commitment to excellence in private aviation. Its impressive performance, spacious and adaptable cabin, and cost-effectiveness make it a sought-after choice for both business and leisure travelers alike. Whether embarking on long-haul missions or shorter journeys, the Challenger 604 stands ready to deliver a remarkable travel experience for all on board.
