Just a question:

when AS velocity gate start moving too fast (because got the jamming) from the RU (manual tracking) gate, it switched off the AS and gates jumps back after hitting certain deviation (which could be different depending of what POLOSA is picked up). Also it happens immediately if the operator pushes PEREZAHVAT V button

Shouldn't it be it switched ON the AS and move the gate back after the gate moves beyond the deviation when in RU?
Because when in RU, than it does not make sense to switch off AS as it is not active. And AVTO PEREZACHVAT suggests the opposite.
