TECHNICAL DEFINITION

The structural system of an aircraft or spacecraft, typically comprising wheels, struts, shock absorbers, and braking mechanisms, designed to support the vehicle on the ground, absorb landing impact, and facilitate taxiing, takeoff, and landing operations.

BACKGROUND

The British Aerospace 146 is a short-haul and regional airliner that was manufactured in the United Kingdom by British Aerospace, later part of BAE Systems. Production ran from 1983 until 2001. Production figures include the Avro RJ, an improved version from Avro International Aerospace, a subsidiary of BAE Systems. Production for the Avro RJ version began in 1992. The Avro RJX, a further-improved version with new engines, was announced in 1997, but only two prototypes and one production aircraft were built before all production ceased in 2001. With 387 aircraft produced, the Avro RJ/BAe 146 is the most successful British civil jet airliner programme.
