Andrei Posted May 12, 2018 Posted May 12, 2018 Sorry if this has been covered before, but I stated to wonder today. Engines off, BAT and APU are running. DMT and FLIR switches are off. Yet, both DMT and FLIR are showing perfect picture on EHSD. While I did not dig very much into the NATOPS I don't believe that battery power bus alone can power those systems, especially when they're turned off. Bug/feature?

mvsgas Posted May 13, 2018 Posted May 13, 2018 Couple of questions; If the APU is running, the generator is running correct? If the generator is running why do you think the battery is running those systems? If the DMT and FLIR switch are off, they shouldn't be working. What does the Enhance Horizontal Situation Display (EHSD) has to do with either the FLIR or the DMT? I think we might be loosing something in translation. To whom it may concern, I am an idiot, unfortunately for the world, I have a internet connection and a fondness for beer....apologies for that. Thank you for you patience. Many people don't want the truth, they want constant reassurance that whatever misconception/fallacies they believe in are true..
Andrei Posted May 13, 2018 Author Posted May 13, 2018 Yeah, I might have not been too clear when writing the original post indeed. So there are two "issues" I see there. 1. The DMT and FLIR are functional i.e. showing the picture on MPCD when their respective pages are selected even when their corresponding switches are OFF in the center console. 2. According to the documentation (NATOPS), power to DMT comes from the MAIN AC BUS, which is not powered by the APU generator. Meaning without engine generator running the DMT should not be possible to turn on regardless of on/off switch position. Ref. pages 2-31 and diagrams section FO-6 and FO-7. Hope this explains it better.
