C-21A 

Overview

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.

Delivery of the C-21A fleet began in April 1984 and was completed in October 1985. Glasco, a subsidiary of Learjet, Inc., provides full contractor logistics support at 16 worldwide locations.
