ISS-64 crews pass manually controlled descent test

The Soyuz MS-17 crew took an exam on the TS-18 simulator in Gagarin Cosmonaut Training Center. The test is aimed to train manually controlled descent in case of an emergency.

The simulator imitates g-loads occurring during the reentry. In case of automatics failure, both the commander and the flight engineer must be able to land the descent module with minimal g-loads and as close as possible to the calculated point.

Traditionally, an exam ticket has four modes with different initial conditions. The cosmonauts performed two dynamic modes each with the centrifuge rotating to provide 4.5 g overload, as well as two static modes.

All operations should be performed precisely, as overloads in manually controlled descent grow in case of inattentiveness. The examination board praised the skills of both prime and backup crews. Just over a week is left until the final tests at Gagarin Cosmonaut Training Center. During the next few days Favory and Kazbeki (the callsigns of prime and backup crews respectively) will take tests on manual approach to the International Space Station and spend a typical day at the station in the ground conditions.
