The Saunders-Roe (Saro) A.19 Cloud
amphibious flying-boat was produced in two forms: as a civil eight-seater and as a military trainer. In the latter role the RAF received 16 from 1933. The large cabin provided accommodation for eight pupils; six pupils and wireless and electrical equipment, navigation instruments and signalling apparatus; or four.pupils and the above equipment for navigational training. Alternatively, the Cloud could be used for flying training, to simulate the conditions to be met with a larger service type of flying-boat. Power was provided by two 253kW Armstrong Siddeley Double Mongoose engines.
