Design and developmentEdit

The Hyderabad was a development of the Handley Page W.8 airliner, initially designated the W.8D, to meet Air Ministry Specification 31/22 for a replacement for the Vickers Vimy for the Royal Air Force.[1]

The Hyderabad was structurally similar to the W.8, and was an all-wooden, three-bay biplane powered by two Napier Lion engines. It was fitted with a single fin and rudder, and was one of the first large aircraft to be fitted with Handley Page leading edge slats, giving good lateral stability.[2]

A single prototype W.8D was ordered by the Air Ministry in January 1923, first flying in October 1923 and was delivered to the Aeroplane and Armament Experimental Establishment (A & AEE) at Martlesham Heath for evaluation against the Vickers Virginia.[1] On the basis of this evaluation, the aircraft, now called the Hyderabad was ordered for use by the RAF.[1]

Operational historyEdit

The Hyderabad entered service with No. 99 (Bomber) Squadron RAF at RAF Bircham Newton in December 1925,[1] replacing the single-engined Avro Aldershot bomber.[2] Deliveries were slow, and accidental losses were high, with a second squadron, No. 10 Squadron RAF at RAF Upper Heyford only forming in 1928.[2] In 1928 and 1929, two Special Reserve squadrons were formed, receiving the Hyderabad as equipment. The two regular squadrons were re-equipped with the Handley Page Hinaidi, an all-metal development of the Hyderabad in 1931, while the final reserve Squadron, No 503, continued with the Hyderabad in service until 1933.[1]
