 All three were to be contained within the same compartment, which was both pressurised and refrigerated for passenger comfort; lightweight ejection seats were to be provisioned for all crew members.Due to features such as the automatic flight controls and stabilisation systems, the pilot was intended to be capable of supervising some of the aircraft's engineering functions as well, such as the control system, cooling and fuel systems.Cooling was a critical issue for the Avro 730; at Mach 2, the external skin was anticipated to reach 190 °C, this would rise to 277 °C at Mach 2.7.
