VNAV on IFD

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi there,
Should I be getting VNAV from my IFD550?

I have an SR22 G2 (Entegra PFD and MFD) with an IFD550 cross-synced with an IFD440 and an STEC55X autopilot. 

After configuring  altitude targets on my active flight plan, I was expecting the TOD to get transmitted to the PFD altitude bug, and the STEC act accordingly, but nothing happens.

Am I missing something? is this something that depends on any IFD configuration or wiring between the IFD's and the rest of the stack?

	Assuming you have 10.3 software, enroute VNAV is being generated by your 550. But at this point only a couple of PFDs will use it - for instance a G5.
