B737 NG bleeds off take off upper DU indications
Hi all

I have noticed that when I have conducted a bleeds off t/o and then re-configured the a/c back to bleeds on config, the Upper Du; ie the (the start valve open, oil filter bypass and low oil pressure) indicators monentarily blink when re-configuring the air systems panel, why is this

Thank you
