The ISIS is powered off the DC ESS bus with an auto-backup to Hot Battery bus 1.
While one can guess, I do not know what is meant by the terms, "accelerometer" and "gyrometer" in the "ISIS" box. The key in that understanding is, of course, whether or not if ADIRS 1 & 3 fail, does the standby horizon fail?
