Beeping noise and autopilot won’t engage

[Philipljung 3]

Hi, when I request gsx they ask me to shut down my engines as usual. I do, but when they are off I hear a beeping noise (beep, beep, beep, beep), after a while it stops but when I turn my engines on again and takeoff. Then my autopilot won’t engage, what’s the problem and how can I fix it? Thanks.

Found out, I just had to turn on my apu before shutting down engines. Of course!

Make sure to fly the tutorial a couple times to either refresh your memory, or give you a solid foundation of knowledge.

The beeping is caused by not having a source of power to transition to (as you've found out), and the beeping is letting you know that you're going to drain the battery if you keep whatever you're doing up.

As far as not being able to engage the AP, that drop in power knocked things offline that you aren't setting back up properly, which would be covered by the tutorial.

Yeah okay, thanks!
