Kevin may have pointed out a problem that is , in fact ,an an important issue.
On my recent flights in north Idaho my 740/stratux did not display tfrs ,but my gtn 650 /gdl88 did .?? I have checked and rechecked settings on the 740 and stratux. The 740 is mounted very much in my line of sight and the 650 not so much and therefore the 740 has become ,right or wrong, the center of attention. Here in my area tfrs do pop up would be good to trust they were being displayed.
Badger, were those TFRs active, or impending? I ask because a presidential TFR appeared in the electronic sky a few days ago, only 6 miles downstream from my house and close to a pair of powerline towers that I can see from the window I'm looking out of right now (viz is better than 6 miles today).
Because I already knew there was to be a TFR, I was looking for it early. About 1.5 days before it was to be active, iFly showed no hint of it. I consulted a Garmin app, and it was easy to see--a bright yellow circle. iFly didn't depict it until about 24 hours in advance, and then it was a pair of dull, brownish concentric circles--on the 740 it looked like dried blood--not much different from any Class C airspace (which it was centered in), and if I had not been expecting it, I might well not have noticed it. Of course, while the TFR was active, it was quite easy to spot THEN in iFly: a bold red circle filled in with a pale pinkish color. But I had visions of flying downstream past my house and suddenly finding a Blackhawk off my left wing.
I've lamented several times about the pale-ness of traffic depictions in iFly. The colors make perfect sense to me; but they're pastel and hard to spot, especially over a VFR chart, and almost impossible to spot in bright sunlight.
Now I'm adding a lament about the muted depiction of impending TFRs.
Yes, I always do check at least two devices before taking off, even when it's to be just a fun flight around the area, with a few splash-and-goes in the river. What I haven't ordinarily been doing is phone a briefer when I'm not going anywhere. Maybe I'll start doing it now.
