The Royal Air Force (RAF) had initially placed an order for 100 Hastings C1s; however, the last six were manufactured as weather reconnaissance versions, referred to as the "Hastings Met. Mk 1", while seven other aircraft were subsequently converted to this standard. These weather reconnaissance aircraft were stripped of their standard interiors, the space being instead occupied by meteorological measuring and recording equipment, along with a galley and wardroom to improve crew comfort during routine flights of up to nine hours. A total of eight C.1 aircraft were later converted to "Hastings T5" trainer configuration, which was used by RAF Bomber Command as a replacement for the Avro Lincoln at their Bombing School at RAF Lindholme. The conversion involved the installation of a large ventral radome; each aircraft could carry three trainee bomb aimers in a training section above the radome. The rear cabin retained a secondary passenger/cargo carrying area, giving it a limited transport capacity as well.
