Understanding the BAe 146 aircraft specifications is crucial for anyone interested in its operational capabilities, design philosophy, and continued relevance in various roles worldwide. This comprehensive overview delves into the core specifications that define this remarkable aircraft, offering valuable insights into its performance, dimensions, and unique features.

Understanding BAe 146 Performance Specifications

The performance specifications of the BAe 146 highlight its design for short-field operations and regional routes. These metrics are fundamental to appreciating why the BAe 146 became a popular choice for challenging environments and noise-sensitive airports.

Key Performance Metrics

• Cruise Speed: The BAe 146 typically cruises at around 460 mph (740 km/h or 400 knots), offering efficient travel for its intended routes. This speed allows for competitive journey times on regional sectors.
• Service Ceiling: With a service ceiling of approximately 31,000 feet (9,400 meters), the BAe 146 operates comfortably above much of the weather. This altitude capability ensures smooth flights for passengers and efficient fuel consumption.
• Range: Depending on the variant and payload, the BAe 146’s range can vary significantly. The longest-range variants can cover distances up to 1,800 nautical miles (3,330 km), making it suitable for a wide array of regional and even some transcontinental flights.
• Takeoff and Landing Performance: One of the most celebrated BAe 146 aircraft specifications is its impressive short-field performance. It can operate from runways as short as 4,000 feet (1,200 meters), a capability that few other jets of its size possess. This allows access to smaller, more challenging airports.

BAe 146 Dimensions and Weight Characteristics

The physical dimensions and weight characteristics of the BAe 146 are pivotal to its operational versatility. These specifications dictate its compatibility with airport infrastructure and its capacity for passengers and cargo.

Aircraft Dimensions

• Wingspan: The BAe 146 features a wingspan of approximately 86 feet 0 inches (26.21 meters). This relatively compact wingspan contributes to its maneuverability at smaller airports.
• Length: The length varies by series. The BAe 146-100 is around 85 feet 10 inches (26.16 meters), the BAe 146-200 is 93 feet 8 inches (28.55 meters), and the BAe 146-300, the longest variant, measures 103 feet 11 inches (31.67 meters). These differences reflect varying passenger and cargo capacities.
• Height: The tail-mounted engines and high T-tail configuration give the BAe 146 a distinctive height of about 28 feet 3 inches (8.61 meters). This design choice contributes to its quiet operation and ground clearance.

Weight Specifications

• Maximum Takeoff Weight (MTOW): The MTOW for the BAe 146 varies by model. For instance, the BAe 146-100 has an MTOW of around 84,000 lbs (38,100 kg), while the BAe 146-300 can reach up to 97,000 lbs (43,998 kg). These figures are crucial for flight planning and payload considerations.
• Empty Weight: The empty operating weight also differs across the series, typically ranging from 55,000 lbs (24,948 kg) for the -100 to 65,000 lbs (29,484 kg) for the -300. This is the weight of the aircraft without fuel, passengers, or cargo.
• Maximum Payload: The BAe 146 can carry a significant payload for its class, with the -300 variant capable of transporting over 24,000 lbs (10,886 kg) of passengers and cargo. This flexibility makes it suitable for both passenger and freighter operations.

Engine and Powerplant Details of the BAe 146

The engines are a defining aspect of the BAe 146 aircraft specifications, providing the power and quietness for which the aircraft is renowned. The specific engine choice was instrumental in achieving its unique operational characteristics.

Lycoming ALF 502/501 Turbofan Engines

The BAe 146 is powered by four Textron Lycoming ALF 502R-5 (or later ALF 501R) turbofan engines. These engines are notable for their high bypass ratio, which contributes significantly to the BAe 146’s quiet operation, a major selling point for urban airports with strict noise regulations.

• Thrust Output: Each ALF 502R-5 engine provides approximately 6,970 lbf (31.0 kN) of thrust. The combined thrust from the four engines ensures robust performance, especially during takeoff from shorter runways.
• Fuel Capacity: The aircraft’s fuel capacity typically ranges from 2,300 to 2,900 US gallons (8,700 to 11,000 liters), depending on the variant. This capacity directly influences the BAe 146’s operational range and endurance.

Operational Characteristics and Variants

Beyond the core BAe 146 aircraft specifications, its operational characteristics and various models further illustrate its adaptability and market appeal. The design catered to specific needs within the regional aviation sector.

Passenger and Cargo Capacity

• Passenger Seating: The BAe 146-100 typically seats 70-80 passengers, the -200 accommodates 85-100 passengers, and the -300 can carry up to 100-128 passengers in a standard configuration. This tiered capacity allowed operators to match the aircraft to route demand.
• Cargo Configurations: The BAe 146 also excels in cargo operations. Variants like the BAe 146-QC (Quick Change) and BAe 146-QT (Quiet Trader) can be rapidly reconfigured from passenger to cargo or are dedicated freighters, respectively. These versions boast large cargo doors and reinforced floors to handle various types of freight.

Unique Design Features

Several unique design features set the BAe 146 apart:

• High Wing and T-Tail: This configuration reduces ground effects and provides excellent stability, particularly during takeoff and landing.
• Four Engines: While unusual for a regional jet, the four engines provide redundancy and contribute to the aircraft’s short-field performance and quietness.
• Airbrake: A distinctive clamshell airbrake located at the rear of the fuselage assists in rapid deceleration, further enhancing its short-field landing capabilities.
