Why do you always see early warning aircraft flying in the sky these days? Is this a drill?

It's just flight training. Flight training doesn't always fly between the stadium and the shooting range. According to the training requirements, it will fly in different places. For example, if you want to train for maritime targets now, you may fly to the sea for training. Residents of coastal cities may often see planes flying here during this time.

Day and night are just the time for flight training. Flying during the day is called Bai Hang, flying at night is called night flight, and from day to night is called crossing day and night. It's midnight, and the night is called dawn.

Extended data:

Flight training, technical and tactical training for pilots to fly aircraft and use airborne equipment and weapons. It is a major training for aviation majors. ?

Including pilot training, single-seat aircraft pilots also need to carry out pilot, shooting, bombing, reconnaissance and other training, pilot, bombing, reconnaissance and airdrop training for aircrew, professional training for aircrew communication, shooting, machinery, electronics and other personnel, as well as training for coordinated actions among aircrew members.

After the Second World War, with the continuous improvement and renewal of aviation equipment, the organization of flight training has become increasingly complex, and the consumption of materials and technical equipment has increased dramatically. Flight training is mainly to study and master complex aviation technology weapons and equipment and train all kinds of pilots.
