The Aero Aeroplane Works built A-304 monoplanes used for observing duties.
The A-304 attained the top speed of 325 kph. Fifteen were built before the German occupation on March 15, 1939. They were confiscated by the Germans and sent to aligned countries, above all to Bulgaria.
The Aero A.200 was a sportsplane of Czechoslovakia, designed and built specifically to compete in Challenge 1934, the European touring plane championships. There two built were four-seater low-wing monoplanes.
Mixed construction low-wing monoplane, braced with wire. Fuselage of a steel frame, covered with wood and canvas, elliptical in cross-section. Rectangular wings of wooden construction, canvas covered, fitted with all-span slats and with flaps. Wings were folding rearwards. Cab had two seats side by side in front, with twin controls, and two seats in the rear, under a common multi-part canopy. Fixed landing gear with a rear skid. Radial engine in fuselage nose, with NACA cowling. Two-blade propeller.
Flown in competition by Jan Ambrož, the A.200 took fourth place, beaten by the RWD-9 (that took both first and second places for Poland) and the Fieseler Fi 97 (from Germany). The other A.200, flown by Vojtěch Žaček, took the 14th place for 34 competitors. They carried registrations OK-AMA and OK-AMB.
In a technical evaluation, A.200s scored the 4th result from among aircraft types taking part in the Challenge. They had the best short take-off capabilities in the contest – A.200s needed 74.5-77.6 m to take off and fly over 8-m high gate, although they needed some 118 m to land from above the gate.

By early 1930s company was making A100 two-seat multipurpose aircraft and A102 fighter. The Aero Aeroplane Works built two prototypes of the A-102.
The Aero Aeroplane Works built A-101, Ab-101 recce-bomber biplanes.
Aero succeeded in winning the Czechoslovakia Ministry of National Defence bid for a recce and bomber plane in 1932, this type was again a biplane. By early 1930s company was making A100 two-seat multipurpose aircraft and A102 fighter.
The wings were wood-framed, covered by fabric, and fuselage, elevator, rudder as well as tail-plane and fin steel-tube-framed, fabric-covered.

Empty weight: 2040 kg
Top speed: 270 kph
Service ceiling: 6500 m
Climb to 5000m: 20 min

The Aero Aeroplane Works built production A-46 trainers.
The A-42 bomber monoplane was built by Aero in 1930, with wooden wing, and steel-tube-riveted fuselage covered by fabric. The engine cowling was sheet metal shaped over an 880 hp Isotta Fraschini Asso engine with a three-blade propeller. Fixed undercarriage.
The Aero A-42 bomber monoplane flown by Svozil made three International speed achievements in 1930 – 252.380 km.p.h.at a 1000 km distance loaded by 500 and 1000 kg respectively and 253.428 km.p.h. at the distance of 1000 km with no load.
Climb was inadequate and hold-off too long. Pilot`s complaints about poor view out of the cockpit covered by a canopy resulted in refinements that proved to be catastrophic in the second prototype.
The Fokker F-IX type was preferred by the Defense Ministry and A-42 production aircraft was not realized.
