Nate--IRL-- Posted December 21, 2009 Posted December 21, 2009 Low Rotor RPM causes this. ACCUM means Accumulators i.e Batteries. When your rotor RPM drops below a certain point the electric generators no longer generate enough power and the Batteries kick in. Note that the batteries can't power all the systems, so stuff like the shkval will trip out. Nate Ka-50 AutoPilot/stabilisation system description and operation by IvanK- Essential Reading

There is a DC-AC converter (POS-500B) in the system that handles "Radar altimeter Power plant's oil pressure switches Fuel quantity indicator, G-load accelerometer, engines RPM and EGT indicators, and vibrations monitoring system IFF equipment Warning and indications systems Audio tones for rotor RPM drop Emergency instrument panels illumination" which is basically the emergency AC bus(es).
