LuseKofte Posted August 12, 2024 Posted August 12, 2024 In start procedure it states this must be turned on according to guide. But says nothing of being turned off In hotstarts this is turned off. Shall it be turned off after start up? During sling load I arm and choose all. Hook first load and release it another place. second load get hooked but unhook again and I have to switch off the arm and on again to get it hooked again after choosing that cargo again. Is this correct? Just wondering. Start to get the hang of it. Can’t wait until it is developed more
Solution Ohatro Posted August 12, 2024 Solution Posted August 12, 2024 The B/U power switch should be left on until you have shut the engines down. It is used for power in the ECU (Engine Control Unit) for the FADEC system. Once the Ng is above a certain level, it is not the primary source but there is no reason to turn it off. Anytime you release a load on any of the 3 hooks, they need to be reset. Therefore, OFF back to ARM is correct, each time. Happy flying. 1
