[edit] Design and development
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 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].
[edit] Operational history
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. The two regular squadrons were re-equipped with the Handley Page Hinaidi, an all metal development of the Hyderabad in 1931, with the final reserve Squadron, No 503, continuing in service until 1933 [1].
