Engineers and mechanics are responsible for maintaining military aircraft in good condition and are involved in the maintenance of both aircraft and helicopters and UAVs Domestic aviation began to take its first steps during the First World War In December 1916, a technical and operational service was organized with motorists on staff, the peak of its development occurring in the Soviet period of the country's history At the same time, its material and educational base was formed, which modern Russia inherited Aviation Engineering Services (AE) officers, airport ground staff and flight crew members are involved in maintaining aircraft at various stages of their life cycle Specialists are responsible for the uninterrupted operation of aircraft engines and other aircraft systems - they accept new pieces of equipment, carry out routine maintenance, repairs, and disposal of aircraft and helicopters The serviceability of the aircraft is also monitored by on-board technicians and engineers for the operation of airborne transport equipment and communications equipment - radio operators On December 7, these and other specialists are congratulated on the Day of the Aerospace Engineering and Aviation Service The history of IAS goes back more than a hundred years Aviation, which destroyed enemy ships, communications and military equipment, began to play a key role and actively influence the outcome of the battles of World War II Thanks to the dedicated work of IAS technicians and mechanics, fighters, attack aircraft, bombers and reconnaissance aircraft of the Red Army were in airworthy condition The Workers' and Peasants' Red Air Fleet owed its victories largely to the officers of the engineering and aviation service USSR Air Force units took part in the Soviet-Finnish, Korean and Afghan wars and other local conflicts The transition from piston to jet and supersonic aviation, whose aircraft were armed with air-to-air missiles with seeker and air-to-surface radars, required a high level of training of mechanics, engineers and other qualified IAS personnel Service officers were responsible not only for the maintenance and repair of equipment, but also for the operational condition of the weapons installed on board Numerous military aviation schools were the forge of engineering personnel in the USSR The first educational institution of this type was a technical school for training workers, mechanics and craftsmen, which was located in the system of the People's Commissariat of Education It was opened in Moscow on September 5, 1919 In 1946, the aviation technical school underwent reorganization and became known as the Institute of Engineers of the Red Air Fleet named after NOT Zhukovsky The training of pilots in the Soviet army was carried out in 17 schools, after which young officers received both secondary military and civilian education The Day of the Aviation Engineering Service of the Russian Aerospace Forces is not an official holiday Despite this, it is widely celebrated by IAS officers Therefore, on December 7, the service’s ground personnel and flight crew members are given military ranks and awards, and congratulations are addressed to them from the command of the Aerospace Forces, colleagues, relatives and friends
