Hi Guys and Gals,
Just to introduce myself, I'm not a real world pilot/engineer, but I am an avid aviation enthuiast and I'm building a fixed base 777 simulator at home, using Microsoft Flight Sim as a base package but with substantial bespoke enhancements.
I am writing my own software to try to bring some level of realism to the systems simulation and at present I'm working on the elecitrcal systems. I have access to a Flight Manual for the 777 , but have a number of questions regarding the electrical systems that are more detailed than the manuals I have cover.
I appreciate that this forum is primarily for real world participants, so please feel free to tell me to get off... or alternatively if there are any 777 engineers/pilots out there who would be prepared to assist me outside the forum in a one-to-one capacity then let me know.
Anyway, now that I've tried to be as honest as possible about my motives, on to the questions:
1. Starting from a completely cold and dark cockpit, with no power sources available, the Main Battery switch is pushed on.
Which busses and systems become powered?
2. Are there any cicrumstances in which a pilot input that de-selects a power source results in the loss of power to a bus even if the bus could be powered by an altermate source, or will the systems logic always select an alternate source if one is available?
3. According the the Flight Manual I have, the MFD Electrical synoptic display will show an amber crossed box for an engine generator control (as opposed to the engine generator drive) if the generator is "not supplying power or failed". Under what circumstances will the generator be "not supplying power" ?
