it's in the bottom  of the PFD frame . It's the "old" style one.

You mean where it says... 'S'. If I keep the artificial wing tip on the 'S' ..its a stad rate turn?

There is no gauge I know of on this panel that tells you when you're in a standard rate turn; the ball on the PFD is of course no help. There is a rule of thumb for standard rate: Take your airspeed, divide it by ten, and add 7, to get your bank angle. For example, at 150 knots indicated airspeed, your bank angle for a standard rate turn would be 22 degrees (15 + 7). However, during instrument flight and as far as I understand it, you're usually supposed to use the angle of bank giving a standard rate turn, or 25 degrees of bank, whichever is less (source: PANS-OPS). So, if your airspeed is 180 knots or above, no need to worry, just use 25 degrees of bank. Maybe that's why there's no standard rate gauge on the panel...

Bjorn that advice is for TAS,
To use with indicated airspeed:
-If indicated airspeed is in MPH, divide airspeed by 10 and add 5 for standard rate turn.
-
If indicated airspeed is in knots, divide airspeed by 10 and add 50% of that value.

The turn coordinator is useless for airliners because most often you will end up with an angle that isn't safe and uncomfortable if you were to follow a turn indicator. It's possible in GA for example because  there's a wide range of airspeed that allows a safe bank for a SRT.

You have to use a turn indicator in this thing too!?  Is it located on the windshield controls like in my truck?  Will it blink the left or right arrow so I know I need to turn it off in case I'm not turning?

In my opinion in Germany you need the turn cordinator (in german Wendezeiger) for CVFR license (JAR FCL) , a large step before IFR. Under IFR condition you fly cordinated turns in reference to your charts (in order of speed restriction, bearing to a VOR, intercept course to another VOR, DME Arc.......).

I meant to say an SRT indicator not Turn coordinator.
