In the Rostov region, the crews of the operational-tactical aviation of the Southern Military District will practice flights with refueling in the air. This reported by Russian Ministry of Defence press-service.

The flight crew of the Su-35 and Su-30SM fighters, the Su-34 and Su-24M bombers will perform the most difficult element of flight training individually and as part of a pair. Flights will take place day and 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.
