Our older Cirrus planes which are the initial target market for Vantage, have an old school turn coordinator gyro hidden behind the panel for the DFC90 to use as a secondary reference. Is there any chance with Vantage having dual ARS, you can complete certification with the DFC90 referencing those as two separate sources, and eliminating the gyro? It'd be nice to save a few pounds and eliminate a common source of problems. ------------- 2006 Cirrus SR22 - IFD540 IFD440 DFC90 AXP322 MLB100 |

It is my understanding that the turn coordinator comparator is not used in the DFC STC anymore. ------------- Steve Lindsley Avidyne Engineering |

THAT would be really great and another good reason for the upgrade ------------- 2006 SR22-G2 DFC90 IFD440 |

Can you clarify this? Could an existing DFC90 install in a Cirrus now remove the TC and how would that be accomplished, i.e. through a software change or ??

I understand that the second AHRS in the MFD replaces the TC in this respect. ------------- 2006 SR22-G2 DFC90 IFD440 |

Yes, you would need the latest DFC90 software. ------------- Steve Lindsley Avidyne Engineering |

| Super. Will remember this when the TC inevitably dies! |

What is the latest DFC 90 software version, we just purchased ours in March and it was installed at our annual in April and the shop that did it kept the TC in there as well Looking at the PFD I can see the DFC90 Top Level Part Number as 510-00874-000_REV03 What would one need to do to get it updated?

Latest version was from 4/10/2014. I don't have the part number handy, but I just happen to have the checksum for that version - 0x69CEC547 (which I'm sure makes me a real geek...). You can check that on the PFD maintenance page. If you need to update it, I'd first start with tech support. ------------- Steve Lindsley Avidyne Engineering |

Okay lookes like I have that version, I see "DFC90 Application: 0x69cec547" So I wonder why my installer thought I needed the TC kept in the plane. Does it do anythin gif it's still there?

It won't hurt anything, but the DFC90 won't use it. ------------- Steve Lindsley Avidyne Engineering |

From a response I found in another thread, the SB apparently only allows for the removal of the TC from planes that came equipped with STEC-30 or STEC-50 APs, but the majority of us whose planes came with the STEC-55X need to keep the TC. I haven't seen the actual text, so maybe AviSteve can help verify this is true. If so, it's a bummer and I still hope Vantage will finally ditch the TC. :)

| Yup I had the STEC-55x so that's why the isntaller didn't remove it, if there's something that shows it isn't being used and could be removed that'd be cool to have. Not a fan of keeping gear in the plane that's not being used |

I can't hear you over the sound of "GYRO MISCOMPARE". I want so badly to toss that thing out... ------------- 2006 Cirrus SR22 - IFD540 IFD440 DFC90 AXP322 MLB100 |

Hey @AviSteve... I am wondering if my DFC90 needs to be updated.. here is my checksum values: I am an (excited!!) Vantage deposit holder... will my DFC90 automatically get an update when we do the Vantage install (hence I just wait for that...everything is working great atm...)? Thanks for any guidance you can provide!  Doug Anson N208LG

Thanks for being an excited Vantage customer! We're making great progress on getting that finished up. While there is a later software version for your DFC90, there are no functional changes in that release. So, your autopilot will not require an update when Vantage comes along. ------------- Steve Lindsley Avidyne Engineering |

Following up on this topic. During testing today, it seems this is mostly correct. The DFC90 did not have any issues performing a ground test with the blind turn coordinator disabled. The PFD did however display "TC Fail" on the top right. Can we confirm Vantage will display no such messages or if there is a future version of PFD software it will not display this message since the DFC90 no longer uses the TC?   |

Correction: If your DFC90 supports a no-TC configuration, Vantage will not show the TC Fail message. If your DFC90 still expects a TC, then the message could appear. In that case, you really should get the software update to the DFC90. ------------- Steve Lindsley Avidyne Engineering |

| @AviSteve... do you happen to know if that software update (for the DFC90) will be part of my vantage update? Thanks!! Doug |

Not that I'm aware of, but it's probably best to talk to someone on the sales team. ------------- Steve Lindsley Avidyne Engineering |

From the checksums given my DFC90 is supposed to be the latest software, how did you disconnect the TC for the test? If it's straight forward I could give it a try and see what mine does. |
