This model is powered by four turbofan engines, positioned under the wings on pylons, contributing to its low noise signature and nickname “Whisperjet.” These engines are not only known for their quiet operation but also for their reliability and performance in various operational conditions.

The aircraft’s construction allows for a blend of speed, efficiency, and short-field capabilities—key factors that support the modern airliner technology landscape.

Cabin and Cargo Capabilities

Internally, the design prioritizes passenger comfort and versatility in cargo arrangements.

The cabin is designed to accommodate between 70 and 112 passengers across different configurations.

The step-up in cargo handling is significant, with features catering to both commercial passenger travel and freight operations.

Its tricycle landing gear supports the airframe on the ground and aids in smooth takeoffs and landings, underpinning its passenger and cargo transport efficiency.

Operational History

The BAe 146 and its successor, the Avro RJ series, have left a significant mark on aviation history, recognized for versatile operations ranging from commercial service to specialized roles.

Commercial Service

The BAe 146’s first flight occurred in 1981, and the aircraft quickly gained recognition for its STOL capabilities, making it ideal for challenging airports. Pacific Southwest Airlines was the type’s North American launch customer, while European carriers like Lufthansa and Eurowings significantly incorporated the aircraft into their fleets.

As the Avro RJ series was introduced, operators such as Brussels Airlines and Flybe capitalized on the aircraft’s performance, particularly at constrained airports like London City Airport.

  • Lufthansa: Key European operator
  • Pacific Southwest Airlines: North American launch customer
  • London City Airport: Demonstrated STOL abilities

Specialized Uses

Beyond typical passenger services, the BAe 146/Avro RJ’s design made it suited for varied uses. Aerial firefighting units, for instance, utilized its maneuverability and payload capacity.

Companies like Conair adapted the airframe for such demanding roles, solidifying the aircraft’s reputation beyond traditional commercial aviation.

  • Aerial Firefighting: Adapted by Conair and others
  • Special Missions: Transport and logistical support roles

Retirements and Legacy

Over time, the BAe 146 and Avro RJ have faced gradual retirements from commercial service due to increasing maintenance costs and newer, more efficient aircraft entering the market. Flybe, a prominent operator, ceased operations while others slowly phased out the type.

Nonetheless, the aircraft’s legacy persists, remembered for its unique qualities in the commercial aviation narrative.

  • Flybe: Prior significant operator before ceasing operation
  • Retirements: Phased out from most commercial fleets

Models and Variants

The BAe 146 and its successor, the Avro RJ series, offered airlines a range of sizes and capabilities in their regional jet offerings.

These aircraft became known for their quiet performance, earning the nickname “Whisperjet.”

The Original BAe 146

The BAe 146 debuted in three main variants aligning with capacity and range.

The 146-100 served as the entry-level model, typically seating around 70-82 passengers.

As the first of the series, it set the standard for the family’s design, including a high wing and T-tail.

Following it was the 146-200, offering a stretched fuselage for roughly up to 94 seats and improved performance.

Finally, the 146-300 emerged as the largest variant, accommodating up to 112 passengers with an even more extended body.

  • 146-100: The shortest, initial model
  • 146-200: Stretched version, more seats
  • 146-300: The longest variant, highest capacity

Cargo versions of these models were designated “Quiet Trader” (QT), emphasizing their noise reduction feature, and “Quick Change” (QC), indicating versatility in converting between passenger and freight configurations.

The Advanced Avro RJ

With technological progress, the Avro RJ series represented an evolution of the BAe 146.

The corresponding variants were reinvented as the RJ70, RJ85, and RJ100, coinciding with the 146-100, 146-200, and 146-300 respectively, but with modern updates and refinements.

  • RJ70: Comparable to the 146-100, for niche markets
