iFly GPS Forum

I tweaked the FlightPhase logic for 8.4.50b to force a 7-second delay before iFly will recognize a new flight phase, to prevent these quick flukes, often caused by a glitch in GPS data, making iFly think it's not "On Ground" for a second... which then resets AutoTaxi and brings up the diagram again.

I also raised the AGL threshold, which in one case I witnessed, also triggered this bug.

I believe you'll find that 9.4.50b has fixed this symptom, for 95%+ of the cases.

Brian is changing it in v9.5 so that AutoTaxi+ does not pop up after you return from the Flight Plan page.

As for other nuisance pop-ups, I have found that when GPS sentences are lost and then reacquired (on the ground), AutoTaxi+ pops up again when the GPS sentences come back. I'm using Stratux v0.8r1 and the developers have found a bug that sometimes blocks GPS sentences.

So, in my case, the problem could be my Stratux. (Although I also get loss of GPS with my tablet's internal GPS. So maybe not totally a Stratux problem.)

Check your iFly log for Warning: GPS lost (or something to that effect.)

If you're getting that too, then I suppose someone should figure out why that's happening. (I'm getting a solid GPS signal.)

Even if that problem with the GPS is fixed, I'm thinking that the most elegant solution is that once the user dismisses the Airport Diagram, the Diagram should not be allowed to automatically pop up again until after Flight Phase is achieved.(But of course, the user should still be able to manually call it up whenever they want.)

iFly triggers AutoTaxi at first (while you're still on the ground, before flight) because you might be starting out at an unfamiliar airport. And so you might want to see the Airport Digram then. (As opposed to only after you land.)

Another way to mitigate some of this is if there were a place in iFly that you could enter your Home airport. Then you could have the option of not having AutoTaxi trigger ever for Home.

It might also make starting many of your flight plans easier, since you wouldn't have to enter your Home airport ID all the time as Departure.
