In June 1983, the RAF leased a pair of BAE 146 aircraft to test their suitability as replacements for Andover aircraft which had served in the VIP role since the mid-1960s. Following successful completion of the trials, three aircraft were later purchased and they entered service from 1986 onwards.
The 146 was the first jet aircraft to be operated by the Royal Flight and offered twice the speed of the Andover, 60 percent greater range, the ability to fly above bad weather and an increase from twelve to nineteen seats in the passenger cabin. Quiet and spacious, the 146 also possesses excellent short take-off and landing capabilies.
