The older Airbus has a crap standby Attitude indicator, it lags badly in turns and it's pitch indication can be 3 deg different to the main ADI's !!
The newer ones with the LCD ISD Displays are good in pitch but lag badly in the turns!!
Now the really new Airbus's are not fitted with DDRMI's anymore, so if all fails you'll need to look at that small crappy compass on the window......
I hope I never need to do it for real.
