The Bombardier CRJ700 changed regional aviation by proving that smaller twin-engine jets could connect low-density city pairs with the speed and reliability of mainline airliners. Developed as a stretched derivative of the 50-seat CRJ200, this 70- to 78-seat aircraft addressed the surging demand for frequency over sheer capacity on secondary routes. Airlines didn't just get a bigger tube; they gained an aircraft capable of cruising at Mach 0.825 while operating out of restrictive regional airports with shorter runways.
Understanding why this aircraft reshaped fleet planning requires looking past manufacturer marketing brochures. We have to examine how its wing geometry, General Electric powerplants, and cabin economics allowed regional carriers to rewrite hub-and-spoke scheduling models across North America and Europe.
Engineering and Design Evolution
Bombardier launched the CRJ700 program in the late 1990s to bridge the performance gap between cramped 50-seaters and larger mainline Boeing or Airbus narrowbodies. Engineers didn't merely stretch the CRJ200 fuselage by roughly 5.7 meters; they engineered an entirely new wing featuring leading-edge slats and optimized sweep angles. This allowed clean low-speed handling during approach alongside high-altitude efficiency.
The aircraft is powered by two General Electric CF34-8C turbofan engines equipped with Full Authority Digital Engine Control (FADEC). Each engine delivers approximately 13,500 pounds of thrust, burning roughly 1,200 to 1,500 kilograms of fuel per hour depending on altitude and payload.
- Maximum Operating Altitude: 41,000 feet, placing the aircraft above most turbulent weather systems.
- Typical Cruise Speed: Mach 0.78 to 0.82 (approx. 828–871 km/h).
- Maximum Range: Up to 2,100 nautical miles (3,890 km) in extended-range configurations.
The flight deck features advanced avionics suite options, including dual-channel Flight Management Systems (FMS) with RNAV and RNP capabilities, plus CAT IIIa autoland functionality on properly equipped airframes.

Cabin Layout and Passenger Experience
The interior cabin measures 2.57 meters in width, configured in a 2-by-2 abreast seating layout that completely eliminates middle seats. This layout became a major selling point for business travelers who disliked the tight 3-by-2 arrangements found on some competing turboprops or older regional jets.
Standard capacity ranges from 68 to 78 passengers, depending on airline specifications and class partitioning. However, overhead bin space on early CRJ models remained notoriously tight, frequently forcing passengers to gate-check rolling carry-on bags. This limitation later spurred specialized variants like the CRJ550, which traded total seat count for floor-level baggage cabinets and spacious first-class configurations to satisfy strict U.S. pilot scope clauses.
Aircraft cleanliness, air pressurization performance, and modern LED lighting refits have kept these cabins competitive even as newer clean-sheet designs enter the market.

Operational Economics and Fleet Impact
For regional airlines operating under capacity purchase agreements with major carriers like Delta Air Lines or United, cost per available seat mile (CASM) dictates survival. The CRJ700 achieves strong fuel burn efficiency—averaging roughly 1.5 to 2.0 liters per seat per 100 kilometers—making it economical on short 300-mile hops as well as longer 1,500-mile transcontinental legs.
Dispatch reliability across major fleets routinely hovers above 99%, driven by mature maintenance protocols and robust hydraulic redundancy. Maintenance crews appreciate the accessibility of the CF34 powerplants, while operators benefit from parts commonality across the broader CRJ family, which includes the smaller CRJ200 and the stretched CRJ900.
Common Operational Challenges
Despite its success, flying and maintaining the CRJ series comes with specific hurdles that operators must manage carefully:
- Weight and Balance Sensitivity: The aircraft is notably sensitive to passenger seating distribution and cargo loading prior to pushback, requiring precise trim sheet calculations by the flight crew.
- Ground Handling Constraints: Because of its low-slung fuselage and rear-mounted engines, specialized baggage belt loaders and tow bars are required to prevent ramp damage.
- Runway Performance in Contaminated Conditions: While capable on short strips, stopping performance on icy or wet runways demands strict adherence to braking action reports and thrust-reverser deployment procedures.
Frequently Asked Questions
What is the passenger capacity of a standard CRJ700?
Most standard configurations seat between 70 and 78 passengers in a single-class or two-class regional layout.
How does the CRJ700 compare to the Embraer E175?
The Embraer E175 features a wider cabin with under-floor cargo bins that accommodate standard rolling bags inside the cabin, whereas the CRJ700 has a narrower fuselage and traditionally requires gate-checking larger carry-ons unless converted to a lower-density layout like the CRJ550.
What engines power the CRJ700?
It is powered by two General Electric CF34-8C turbofan engines controlled by dual-channel FADEC systems.
What is the maximum range of the extended-range CRJ700ER?
The extended-range variant can fly up to 2,032 to 2,100 nautical miles depending on payload weights and weather conditions.
