The fuselage area behind the pressurised crew section and forward of the wing was used to house much of the Valiant's avionics, and air conditioning equipment, and was sometimes called the "organ loft". The Valiant had twin-wheel nosegear and tandem-wheel main gear that retracted outwards into recesses in the underside of the wing. Each of the main gears were equipped with multipad anti-skid disc brakes, and were telescopically linked so that a single drive motor could pull them up into the wing recesses. Most of the aircraft's systems were electric, including the flaps and undercarriage. The brakes and steering gear were hydraulically powered, the hydraulic pumps being electrically driven. The lower half of the aircraft's nose contained the scanner of the H2S radar in a glass fiber radome; in addition, a visual bomb sight was set beneath the lower floor of the pressurised cockpit. The avionics bay was not accessible from the cockpit but could be accessed via an entrance at the base of the rear fuselage leading to an internal catwalk above the aft of the bomb bay.
