Hello Rob, first of all thank you for all your great videos! I noticed that you always have the AC/DC UTIL OFF before applying the APU GEN. A mechanic once told me to do that to avoid "voltage spikes" on startup, however I was unable to find any reference/guidance for this in the usual manuals (e.g. FCOMs, PTG, AMM, etc.) Did you by any chance ever find such a note? Or are you as well just going by a maintenance guy's recommendation? Thank you!
