D-41 Avro Anson were used for submarine patrols as well as supply duties and advanced training of bomber pilots. Powered by two Armstrong Siddeley Cheetah engines of 335 hp each, this type achieved the maximum speed of 300 km.p.h, range 1060 km and service ceiling 5 600 m. Span 17.20 m, legth 12.90 m, empty weight 2 440 kg, steel-tube welded fuselage covered by fabric, wood-framed wings, fin and tailplane covered by plywood, steel-framed elevator and rudder covered by fabric.Tail wheel fixed.

S-92 Messerschmitt Me 262. Because Luftwaffe pilots succeeded in flying all the airworthy Me 262s to the zone occupied by the American Army early May 1945, every airframe found on the Czech territory after V-E Day had to undergo reconstruction in the Avia Letnany plant. The first airframe was ready for fitting engines in autumn 1945. The first S-92 with the Avia Company`s test pilot Antonin Kraus at the controls got aloft on August 27, 1946. But the S-92 concept proved to be outdated at that time already.

S-92.Czech-built Messesschmitt 262s powered by two 8.80 kN-thrust Juno 004 engines attained the maximum speed of 870 km.p.h. This type was able to one-engine-fly if being at state of emergency. Range 1050 km, service ceiling 11000 m. The underslung engines were housed in nacelles. Both undercarriage struts were detracted towards a hull,a nose wheel backwards. Alclad all-metal airframe.

The latter was designed by a Soviet Mikoyan-Guryevich`s staff and licensed-built in the Czechoslovakia  coded S-102 and a double seat version MIG 15 bis as the S-103 one. Span 10.08 m, length 10.10 m, empty weight 3 382 kg, powered by a 22.30 kN-thrust RD-45F engine. Top speed 1070 km..p.h., service ceiling 15 200 m, range 1 600 km. Armed with two 23 mmm-cal and one of 37 mm-cal nose-mounted cannons. Alclad skinning of the fuselage of duralmin-semicircular-moulded construction, as well as steel-framed wings, tailplane, rudder and elevator. The undercarriage of  the MIG 15 was retracted the same way as in the Me-262 type.

S-92 Me 262 nicknamed Schwalbe ie Dove was a type of the dimensions as follows : span 12.51 m, length 10.60 m and empty weight of 4 420 kg. Armed by two or four nose-mounted 30 mm-cal cannons, but most of S-92s were flown without them. The all-in –silver PL-01 machine with a red arrow had never got aloft because it was used in the Fighter Pilot Training Center. All the other machines of this type bore the camouflage of a mixture of gray green..

S-99 Messeschmitt Me 109 of G- and K versions were the most commonly used fighter planes flown in the Czechoslovakia after the end of hostilities. Twenty one Messerschmitt Bf 109s were overhauled in the Avia Company and coded S-99. Span 9.92 m, length 8.94 m, empty weight 2 520 kg. Powered by a 1 430 hp Daimler Benz engine, this type achived the maximum speed of 600 km.p.h. Armed by two synchronized machine guns and a through-the propeller-axle shooting cannon. Three blades of the propeller fully articulated. Undercarriage members retracted towards wingtips, a tailwheel fixed. A steel-framed fuselage and wings fabric-covered, wooden frame of a fin and a tailplane covered by plywood, an elevator and rudder fabric-covered.
