Russia's so-called Superjet

When was the last time a modrn airliner had such a malfunction, btw (total loss of power)? I'm just curious.

Read the NTSB records - I'm sure you'll find some power loss scenarios. By the way, an EPU should take care of most power loss situations.

EPU = RAM air turbine?

EPU is the emergency power unit. Has its own independent fuel source and typically runs long enough to put an aircraft on the ground in a power loss situation.

EPU = APU?

Never heared of this EPU, I only know APU (mostly used for power supply on ground and starting the engines, if no external power is available, is being fueled by a normal tank even if the fuel pump are non-active, and the valves are closed) and RAM air turbines (being meant to be deployed into the airstream to generate power by a propeller, usually cannot be restored in-flight, only on the ground).

An EPU is present on most jets I think, but not sure the actual availability. The APU is not the same since it is dependent on internal fuel of the aircraft itself, not an isolated system.

Maybe I should research this.
