This talk of power assurance and generators reminds me of an interesting Arriel trivial fact.

When you are against a N1 limiter, increasing the generator load will actually increase the engine power delivered to the transmission.

This is because the gene is driven by the N1 shaft. If you are on a N1 limit, then increase gene load, you'll very slightly drag down the n1 shaft. The DECU adds slightly more fuel to get the N1 back up to the limited speed. BUT, the added fuel flow also results in more energy delivered to the N2 turbine. More power. Yes, test data shows this to be true.

So, if you're on the 30sec limiter and are not quite going to clear that obstacle, DC POWER ON !!!

Of course, this doesn't hold true if you're on a torque limiter.
