Are our IFD units ready for Week Number Rollover?

The IFDs are not currently ready for the rollover.  Our plan was to include the fix in 10.2.3.1.  But, since we're not sure how long the government shutdown will last, we're considering a minor release specifically to address *only* the rollover.  We believe that we can push a time critical release like that through the system regardless of the shutdown status.  One way or another, we expect to have an update to address the rollover by the end of February.  Look for further official communication regarding this subject in the near future.

We've characterized the effects of the rollover and those effects are all minor.  For example, database names and cycles will be displayed in yellow because the IFD thinks that the database is not effective yet.  Rest assured that the rollover will not affect the ability of the IFDs to perform normal navigational functions.

If this could be a simple user update with a usb stick and not involving a trip to the avionics shop (which are all overloaded it seems), that would be greatly appreciated.

For those Avi users not on the Forum, suggest you send out an email blast to all owners, so they don't freak out when they see the message, and barrage you with calls, emails.

All Avidyne IFDs will require a MANDATORY update to address the GPS week rollover that takes place on April 6, 2019. This update is necessary to maintain proper display of ADS-B and SXM weather as well as other date related functions including proper display of database currency. No GPS/NAV/COM functions are affected. 10.2.x.0.A for 10.2.x.0 is available now to address this issue and 10.2.3.1, when released, will also incorporate this update.

Here are your options for updating the software to address the GPS rollover issue:

1. Update the IFD with 10.2.3.1 when it is released to get the enhancements plus address the GPS rollover date issue.

2. Update the 10.2.x.0 software with 10.2.x.0.A patch to address the GPS rollover date issue only.

3 Update the 10.1.x.0 software with 10.2.2.0.A to address the GPS rollover date issue and bring the IFD to the latest software rev.

FAQs for Software 10.2.x.0.A:

1. What happens to my IFD if I do not update it to address the GPS rollover issue? On April 6th at midnight GMT the system will report the date as being approximately 19 years in the past. Even if you are using a current navigation database, the system will show that the database is not yet valid. If you are using SXM or ADS-B weather, you will lose access to some of your Datalink weather products. NAV/COM functions are not affected.

2. If I am not at 10.2.x.0 what do I need to do to apply the patch to address the GPS rollover issue? You may elect to update your unit to 10.2.2.0.A which must be done by a dealer or you can wait until the 10.2.3.1 release is available and update it at that time.

3. Does an Avidyne authorized dealer have to do the 10.2.x.0.A update? No, anyone who can sign off on a log book entry can provide the 10.2.x.0.A update if your software is at 10.2.x.0. It should take less than 30 minutes to complete the update.

4. Does the GPS rollover issue affect my EX5000, EX500 or EX600? No. However, if those products are interfaced to IFDs or other GPSs that are affected by the date rollover issue then the GPSs must be updated in order to maintain correct date-related functionality on the MFDs.

5. On what date will shipments of new IFDs from Avidyne include the GPS update to address the rollover issue? Any new IFD shipped from Avidyne after Feb. 11, 2019 will not require a software update in order to address the GPS rollover issue.

6. How do I get the 10.2.x.0.A software update? You may request the software update at the link that follows: https://lz314.infusionsoft.com/app/form/gpsrolloverupdate

Thanks for info.  I'm not going to be anywhere where I can update to the new version including the rollover fix until mid-May. But I will be flying.

Just so I'm clear on what will happen when I fire it up.

I'll get an error message but all Nav data, obstacle and terrain will be available as always, and the unit will function normally.

Is that right?

Nav, obstacle, and terrain will continue to be usable, but will be displayed in yellow (versus white).  Com/Nav radios will still function normally.  GPS navigation and guidance will still function normally.  Time stamped ADS-B weather won't be displayed.

Sorry for the delay.  I think it's fine worldwide, but I haven't been able to get 100% confirmation from our cert specialist.  I'll post when I get that confirmation.

Thanks for the post teeth6.  

I unfortunately updated to 10.2.2.0.A and spent about 40 minutes wondering why my ifd100 would not work.

I verified the new Check Sums about 20 times before giving up.  

Glad to know that the problem is with app update.  I wish that had been in the update instructions.

This brings two IFD100 update questions to mind:

1) Will the next IFD100 release be backwards compatible with IFD4XX/5XX sw:10.2.X.0.A, 10.2.X.0?

2) Will the next IFD100 release still be compatible with iPad iOS 9.1 or greater as it currently is?

Just saw new IFD100 release. App Store shows it is compatible with IFD software release 10.2.2.A?? I think they meant 10.2.2.0.A...does that mean it is not compatible with 10.2.1.0.A or backwards compatible with 10.2.0.0, 10.2.1.0, or 10.2.2.0?

BTW - new IFD release still requires iOS 9.1 or later....that answers my question a few posts back.

IFD100 app store version 10.2.6 is compatible with all panel mount IFDs 1.2.2.0.A and prior.
