 The C-21A, the military version of the Learjet 35A, provides cargo and passenger airlift and can transport litters during medical evacuations. The C-21A's turbofan engines are pod-mounted on the sides of the rear fuselage. The swept-back wings have hydraulically actuated, single-slotted flaps. The aircraft has a retractable tricycle landing gear, single steerable nose gear and multiple-disc hydraulic brakes. The C-21A can carry eight passengers and 42 cubic feet (1.26 cubic meters) of cargo. The fuel capacity of the C-21A is 931 gallons (3,537.8 liters) carried in wingtip tanks. The safety and operational capabilities of the C-21A are increased by the autopilot, color weather radar and tactical air navigation (TACAN) system, as well as HF, VHF and UHF radios. The aircraft has a crew of two and may be flown from either cockpit seat. It is equipped with an automatic navigation system to enhance crew efficiency. Four cathode ray tubes display essential information to the pilots.
