One uncommon feature of the F28 was the movable split-sections installed on the tail cone; these would be hydraulically opened outwards to act as a variable air brake. A similar approach had also been used on the contemporaneous Blackburn Buccaneer strike fighter and on the later-built British Aerospace 146 regional airliner. The design is unique in that it not only slows the aircraft down rapidly, but also it can aid in rapid descents from economic cruising altitudes and also allowed the engines to be set at higher speeds, which helped eliminate lag time. This means the engines respond faster if needed for sudden speed increases or go-arounds on the approach to landing. The Fellowship had a retractable tricycle landing gear, which used large, low-pressure tyres, enabling the use of unpaved airstrips. The use of antiskid brakes on the main wheels of the undercarriage also contributed to a shorter landing run.
