Jascha Posted February 13 Share Posted February 13 (edited) Thanks. I haven't seen that before. From the top YT comment, I gather it has been posted here somewhere already. It's worth noting that this is a procedure with cold-start using external (ground) power source. Edited February 13 by Jascha Link to comment Share on other sites More sharing options...
admiki Posted February 13 Share Posted February 13 There is no difference in procedure, except for DC switch to isolate battery from APU starter. Link to comment Share on other sites More sharing options...

Dataduffy Posted March 2 Share Posted March 2 great video. Thanks for sharing. Quick nerdy question. at 3:48 in the video, he switches on the two batteries, selects "power from battery", but then switches on Tank 1 & 2 fuel pumps before checking the battery and bus voltages. He then switches the tanks off again, before hooking up the external power. Any idea why he powered up the tanks? Is it to create some current draw on the battery for the tests? As I said... nerdy question, but I am genuinely interested. Link to comment Share on other sites More sharing options...

Service tank 1/2 on Check tank 1/2 lights and battery voltage then turn tank 1/2 off 1 1 Black Shark Den Squadron Member: We are open to new recruits, click here to check us out or apply to join! https://blacksharkden.com Link to comment Share on other sites More sharing options...

Is my assumption correct that switching on the pumps is to create a load on the battery for the check? Can you also please point me to where I can find the checklist you refer to? I have looked through the quick start guide again, but I can't seem to find it. Probably me being blind! Many thanks again. Link to comment Share on other sites More sharing options...

It’s not in the guide, I am referencing real world checklist I likely shouldn’t share here Fuel pumps need battery power to work. So you are checking both batteries and that the fuel pumps work. When you turn on fuel pumps, green annunciator lights above them turn on. So you are checking that both battery and fuel pumps work 1 Black Shark Den Squadron Member: We are open to new recruits, click here to check us out or apply to join! https://blacksharkden.com Link to comment Share on other sites More sharing options...
