The 350i is working great for me, but there is one glitch.  The battery operated PFD above the radio, center panel does not work at all.  Could I be missing some file.  I'm not sure what;s it's called or where to look.

Thanks.

It's called the ESIS, and it has a separate power switch located to the lower left of master gang bar, below the red/white striped Battery Bus switch. This rendition of the Proline 21 avionics needs major work, but glad it's working for you.

Thank you, thank you.  I had wondered if I was missing a switch somewhere, and there it was tucked down in that corner.  Sorry too about incorrectly referring to it as a 'battery operated PFD'.  I knew it had a name I just couldn't remember EFIS...Electronic Flight Instrument System, I guess.

 

I've heard what everyone is saying about the Proline 21.  So far I've only flown three flights but it's worked okay for me.  I'm flying it like I fly the other King Airs just using a simple flight plan and controlling the altitude myself on the autopilot.  I'm not using the Vertical Speed Nav buttons at all, so for me it's working fine.  I wish the GTN750 could be used instead like most everyone else.  I seldom fly one flight in it's entirety at one sitting.  Therefore I have to re-enter the FP each time I start back up again in the B350.  The GTN would have it saved for me.
