ATR 72-600

Brief description of the issue:

As you can see at the screenshot below, the left engine is stopped (completely) and hydraulic crossfeed is disabled, yet somehow the pressure from the right engine (which by the way with propeller break since it is stuck) going to the left part.

Provide Screenshot(s)/video(s) of the issue encountered:

Detailed steps to reproduce the issue encountered:

Start right engine with prop break.
Set condition to ‘Auto’
Leave the hydraulic crossfeed button off (i believe it’s default position)
Hydraulic pressure is present in the left part of the system.

Expectation:
Hydraulic pressure can’t be in the left part of the system since there’s no magic to bring it there and the valve is closed.

PC specs and/or peripheral set up if relevant:

Build Version # when you first started experiencing this issue:

1.33.8.0

If relevant, provide additional screenshots/video:

This isn’t a bug. Its the way the ATR hydraulic systems work.

The hydraulic pumps are powered by the AC Wild generators. The ACW Generator on engine number 2 is powering both hydraulic pumps. If you look on the screen print you provided this is shown by the thinner green line connecting the two engines.

Thin green lines are signifying electrically powered and the thick lines are hydraulic pressure.

The hydraulic cross feed valve is used if there is a hydraulic pump failure and does function correctly.
