In the Rostov region, the crews of the operational-tactical aviation of the 4th Army of the Air Force and Air Defenсe of the Southern Military District performed flights with air-to-air refuelling.

Pilots of Su-35 and Su-30SM fighters, Su-34 and Su-24M bombers, both singly and as part of a pair, practiced complex flight training. The flights took place by day and at night.

Air-to-air refuelling will be carried out at altitudes of 5-6 thousand meters at a speed of about 600 km/h at a distance of less than 20 meters between the attack aircraft and the Il-78 air tanker.

At night, refueling will be carried out using additional lighting installed on both the refueling aircraft and the aircraft being refueled.

Air refueling is a necessary element of pilot training that allows you to significantly increase the combat range of aircraft and perform tasks for their intended purpose at a far distance from their bases.
