With the power immediately restored, the APs wouldn't come back on (no answer to that yet either)
Probably to do with the AHRS coming back on line - typically (with other types I know of) they take about 30 seconds on ground, about a minute in level flight and up to 3 minutes on a moving deck or unstable flight.
Like I say, if you screw that up IMC or on one of those famous 'VFR-but-very-dark nights' then you are dead. I guess if you are in autorotation for 3 minutes (6 to 8,000 feet required) you might make it out the bottom assuming you don't adopt the flying qualities of a house brick in the meantime.
Best solution in the interim is a good CRM policy - check, cross-check and double check. This helicopter deals with a double gen fail better than any other with no loss of APs or coupling in the first instance. You have the opportunity to get your collective (unless you are HELISKI or others that fly single pilot) heads together and make a plan. DO NOT RUSH is the key philosophy.
I have heard some intelligent suggestions that involve switching off some heavy consumers (fuel pumps and MFD) immediately but we have to teach what it says in the book so you can expect me to skate over such suggestions wearing a crinkly grin.
