The marketing name A 210 is usually used to refer to Aquila's light side by side two seat aircraft, though its official engineering and certification name is Aquila AT01. Design work started in 1997 and the first flight was made in March 2000.
The A 210 is entirely built from carbon and glass fibre reinforced plastics (CFRP and GFRP). CRFP is used for the more highly stressed members, spars, frames and stringers, GFRP for shells and control surfaces, the latter with GFRP/polyurethane sandwich construction. The low wing has straight tapered inboard sections with increasing sweep outboard and winglets at the tips on production examples. It has a laminar flow section and 4.5° of dihedral. The ailerons are balanced and the inboard single slotted Fowler flaps have two positions.
The A 210 is powered by a Rotax 912 flat four engine driving a two blade propeller. The cabin has uninterrupted transparencies fore and aft, with a slender fuselage behind. The canopy is forward hinged. The tailplane is set just above the fuselage and the fin is swept. A small ventral fin doubles as a tail bumper. The A 210 has a fixed tricycle undercarriage. Its mainwheels are fitted with hydraulic brakes and mounted on spring steel legs from the fuselage. The nosewheel has rubber suspension and is steerable; speed fairings are fitted on all wheels.
German certification was achieved in 2001 and deliveries began the following year. It gained US certification in 2003. Early sales were to clubs, mostly as training aircraft. Most have been sold in Europe and overall 120 have been built by late 2010. 110 appear as Aquila AT01 on the civil aircraft registrations of European countries excluding Russia in 2010.
