iFly GPS Forum

Can someone remind me how to make TFRs visible when the map is zoomed out? I see them only when the map is less than 400 miles wide. That's not useful for planning any but short trips.

Brolin, I think the problem is that the 740/740b apparently doesn't get TFR data via ADS-B. At least, I don't recall ever seeing a TFR on my 740 except after I had updated everything at home. (I mean temporary  TFR; the Washington DC "TFR" is effectively permanent and always shows up on my 740.)

I don't know whether my iPhone gets TFRs via ADS-B or the cell network; but it does get them, so I rely on the phone for TFR and other transient data.

The problem is in updating a 740 that's installed in an airplane. You have to either have a wifi connection where the airplane is kept (I don't), or else update the SD card by one method or another. Updating the card probably means you have to remove the 740 from the instrument panel in order to get at the card. So it's not much harder to just take the whole thing home and update by wifi.

We all know (by now) that the 740 hardware has limitations. On the other hand, its display is SO much brighter than any iOS device and probably than any Android device, too; so we who have a 740 installed in a brightly lit cockpit really want to keep it.

I use the iPhone for TFRs and many other navigation tasks. But I'm going to buy an iPad Mini 6 to use in place of the phone. The Mini 6 is no brighter than the phone; but it's about twice as big, and that makes it somewhat easier to read.

But I'd much rather have a 740-style hardware device installed in the airplane, with a bright display and the autopilot connected to it. That's my main reason for choosing iFly instead of the dozen or so almost-as-good iPad aviation apps. So I really wish you guys could find a modern replacement for the 740, even if that would require you to compile iFly for yet another operating system.

For what it's worth, I really appreciate Apple's recent efforts to make all of its devices--computers, iPads, iPhones, watches, Home Pods--talk seamlessly with each other. That's one of iFly's great strengths--it's much better than any of the other aviation gizmos--but if you don't use a lot of Apple devices regularly, you might not appreciate how useful it is.

Yes, thanks for reminding me, Mike.  I did that several times, using the iPhone as a hotspot. But that was before installing ADS-B in the airplane. ADS-B connects to the 740 via wifi, and I assumed (without actually trying) that the 740 can connect to only one wifi router at a time. I thought that connecting to the phone's hotspot to get the update and then connecting instead to the ADS-B router was just a little more than I'd want to do while warming up the engine. But now that you've mentioned it, I'll try to see if the 740 can handle two simultaneous wifi connections--if only to be sure it can't. (I take "never assume" seriously when I manage to think about it.)
