The iFly software (and likely most others) can be set so the GPS attached to or installed as part of your ADS-B Receiver will be your primary GPS when it is receiving, and will default back to the internal GPS when it isn't. I use the iFly Software with a SkyGuard TWX ADS-B on both an iFly 740 and a 7" Android. Each of those displays has it's own distinct advantage. The iFly hardware is much more heat tolerant and rugged. The Android (or ipad) can pick up weather via the cell network before the ADS-B wifi comes up, so you get all the TFRs and a nationwide radar snapshot and it has an extended battery life if you lose power for some reason. The iFly 740 keeps the power on long enough to shut down. Somuch for their 15 minutes of battery time. So far the iFly software is not displaying TFRs as provided by the ADS-B receiver. That's supposed to be fixed in a future version.
-Jeff Scott Los Alamos, NM --------------------- ?I've been using an iPad in the airplane for several years, and am happy ?with it. I took this advice and purchased the IPad mini because it fits on my panel in a holder that I built. ? The full ipad would never have fit. I installed it vertically to leave more room, I seem to be adding more stuff to my console. ?I purchased the iPad mini at a pawn shop for $25. ?Came with a case and charger. ?I am running the ifly gps app, I like the bigger menus because of my fat fingers and airplane vibrations. I am not happy with my gps reception but plan to get the ads b with gps antenna that connects with wifi. ?I hope that will help. Joe Nunley?CW2 US Army RetiredBaker JROTC Instructor?Baker Florida?
