1. Aero Ab-101.49, 73. letka, 5.LP, Brno, 1938
There was not the expected increase in speed over its predecessor, although climb rate and range increased slightly. The aircraft also carried a larger bomb load and improved its ability to operate from shorter runways at field airfields. The type was produced mainly because it was not possible to begin production of aircraft of a more modern design in the short term. In operation on the field airfields, where the machines spent almost continuous time from the end of May to the beginning of October 1938, the wooden parts of the wings were getting wet, so the aircraft had a limited speed in descending flight to 300 km/h. In combat, when the weather was suitable, taking advantage of cloud cover, they could serve effectively during the day. The aircraft carried bombs weighing up to 200 kg, some in the fuselage bomb bay, some on hangers under the wing. During the mobilization in 1938, 60 of these machines were in service with the Czechoslovak Air Force, which were captured by the Wehrmacht after the occupation in 1939.
