Thanks for this interrsting video.
What does the DING DONG sound mean at 6:34?
Do you have the possibility to make a test of the RAAS in tte 737NG?
Of course only if it is availible.

It's just a self-test of the PA system on start up. Nothing to do with Stby power. The RAAS is not fitted on our B737 I belive, but I will look into it to make sure.

Why is it only 1 Drive light when standby power turned off here?

[@rjtaylor3535]

Great question. Is this video in a simulator or aircraft?

What is the buzzing sound at the beginning when you turn on the battery ?
