Get updated before heading to Oshkosh. Does anyone know why the IFR/VFR charts aren’t available from Garmin until the day before they become effective? ForeFlight has them several days in advance. I’m leaving for Oshkosh early on the 17th. It would be nice to update everything effect 7/18 today instead of tomorrow before our planned 6:00 AM departure. When Garmin says it’s available on the 17th, is that Zulu time? (5:00PM PDT) Quote Link to comment Share on other sites More sharing options...
Deb Posted July 16, 2019 Report Share Posted July 16, 2019 From http://www.ifr-magazine.com/issues/33_7/features/A-Date-With-AIRAC_1248-1.html: “The AIRAC date occurs every 28 days on a Thursday. Each country determines the exact time of the switchover to coincide with low air traffic volume. In the U.S. it is 0900 Zulu or 1200 a.m. to 0400 a.m. local depending on time of year and zone.“ 3 Quote Link to comment Share on other sites More sharing options...
Steve W Posted July 16, 2019 Report Share Posted July 16, 2019 Generally the FAA provides plate updates about 2+ weeks before their effective date and that's when I try and get them for my website. Because I can easily allow users to choose a version to download, I do that. For the sectional/IFR charts I typically update the weekend before since they're mostly used by people using them for Google Earth and not a display that could be used in-flight.

(5:00PM PDT) I have already updated my GTN650 card. flyGarmin.com allowed me to update with the current or new database. I did that on Sunday.

amillet Posted July 18, 2019 Report Share Posted July 18, 2019 It looks like the VFR/IFR database is for the portable devices. I was able to update my GTN750 on 7/16 Quote Link to comment Share on other sites More sharing options...
