iFly GPS Forum

I just saw your other post now, where you uploaded an ADSB to here:

For the aircraft "5199B" which was in the pattern with you, was it showing up in another EFB while not showing in iFly GPS?

I have requested permission to read this upload.

Ian, I have reviewed the ADSB logs, and in my test, saw N5199B the whole time.   In fact, it usually showed up twice (two copies).   This was the only aircraft that showed up twice.  Perhaps it has special equipment for ADS-B Out, and so we're getting position from both the plane and the tower?  (and they are skewed)

On 7/27, N5199B stayed around GYR the whole time, in pattern.

On 8/3, N5199B took off after you, did a couple loops, then flew on to BXK to the west.   So it wasn't in pattern with you because it was to the west.

You can do these replays yourself now with version 11.1, by selecting "Menu => Simulation Mode => Replay ADSB Log" and select it from the list.  You can run it at 10x normal speed to save you time, while also being slow enough for you to witness what happened.

Please try this, and see if it compares to what you remember seeing while on the actual flight.  It's possible we have a bug that is more elusive.

Ian, once you learn how to do the "Menu => Simulation Mode => Replay ADSB Log", you will be able to run a review of the performance while on the ground, to confirm what you saw.  Additionally, maybe you'll see that in replay mode, it behaves differently (although it shouldn't, and if it does, then we have a strange bug to squash).
