I presume you spotted their mistake straight away???
Ian,
Hmmm… I have a confession: I haven’t actually seen that cover in real life - only in that picture. My copy is the previous edition - it looks like this:
Is the error evident on the small picture I posted? Seems a little strange that there are Glideslope and LOC indications showing, but the course isn’t lined up with the runway (and he’s not turning)… but I must admit, I don’t see anything wildly out of kilter.

I bet any IR rated PFD pilot would spot the problem within 30 seconds, and anyone that doesn’t should not be flying IFR in a PFD airplane!
well I looked at the picture earlier in this thread a bit but I can’t see anything wrong.
But I still fly IFR in my PFD equipped plane.

I was then immediately sceptical, as I saw the error on the PFD on the front cover.
Flying with the PFD takes a while to become automatic, but I instantly saw the problem with the view.Ian
What’s wrong with the picture?? It’s making me crazy!!
The only thing I see that it might be is the turn coordinator shows a 1/2 standard rate turn to the right while the AI shows no turn…
Any other ideas!!??

I think I know why their photo is wrong.
Inside the cover of the new addition is a picture of the Avidyne kit installed in a Cirrus. “With special thanks to Avidyne”. It also says “front cover artwork provided by Avidyne”
The Picture is taken at an angle, and the readings from the PFD seem to match the front cover exactly, like they have “cropped” the PFD section from a bigger photo.
But in the rest of the photo on the inside cover the MFD is on the engine page showing 2500 RPM. The giveaway is that the REAL RPM dial is reading ZERO - the engine is off!
I think the photo must have been taken with the equipment hooked up to some sort of test harness at Avidyne or Cirrus.
I still think the author should have used a picture for his cover that reflects a real flying situation, and not an instrumentation failure! You don’t want people reading this book thinking this situation is “normal”

All I can see is a 1/2 standard rate turn but no turn on ADI.

Yeah. I don’t think that the PFD is supposed to be displaying an advertisement for Rod Machado’s Instrument Pilot’s Survival Manual. [;)]

You are exactly right!!!
Its even clearer if you have the book in front of you.
In a conventional aircraft, of the turn coordinator shows a bank to the right, and the AI shows wings level, you would be alarmed right?
In this view, the pitch is correct, slightly nose down, reflecting a slight decent to the target altitide of 1900, with the wings level.
BUT the turn coordinator is showing a turn to the right. This might be possible in a yaw based turn - but the slip pyramid shows no slip at all!.
One complaint I had about the PFD after my demo ride was “where is the turn coordinator?” its not obvious to the new pilot. Now I like to think of the turn coordinator as “rate of change of heading” and logically its the blue trend arrow on the HSI.
But I think this excercise proves that its not as intuitive as a traditional turn coordinator which would show wings banked to the right. Get the book amd shove it under the nose of PFD pilots and see what thyey think.
To me seeing half a rate one turn with wings level made the alarm bells ring in my head.
Another strange thing is the function keys on the right, on our aircraft HDG is the top button, followed by ALT and then VSI, on this picture they are ALT, VSI then HDG strange eh?

You’re probably right… However I just purchased the book on-line… Who gets the commission? COPA is good for the economy!

John,
You are right about that!
