Description:
I got night current again recently, with 4 landings (3 for currency) and 1.8 hours of flying, mostly away from the airport. The iFly GPS was running beta software that made the screen so bright that I had to turn up all the other instruments in order to see them. That blitzed my night vision. There were a couple of other minor problems, too, but all in all it was a lovely flight. I also experimented with the iFly's new synthetic vision (the beta test subject, now in the release version). It's visible in two of the landings.

Very cool Don! It's a blast flying at night. Although you do find a lot of adjustments that you have to make, that are not
an issue during the day. I use my little cockpit flood light to light my panel just enough so that I can see my prop
controller. But if it is the slightest bit too bright, it causes my Skyview to go to full brightness as if it is daylight! Also,
there is also that reflection of the Skyview and my Ipad in the canopy. If I turn the displays down low enough that it is
not an issue, I can't see them! Besides that, the Searey is a wonderful night flying airplane!

Jeff, my own view wasn't quite as bad as the video camera saw. Here's a frame from a camera that was on my cap, about 2 inches above my line of sight. It doesn't have much of the reflections on the windscreen--but it does pick up some light from the left landing light that was hitting the nose deck (because I had left off the shield that normally blocks it). And, of course, the iFly GPS was overwhelming everything, even though it was as dim as it would go.

And here's a detail from the shot above, showing the iFly app on an iPhone 6 Plus on the left and the iFly 740 in the center. Both are displaying my position, but differently: The iPhone app was showing a sectional full-screen, with the syn viz EFIS diminished at the bottom. The 740 had the EFIS filling the top half of the screen, above the sectional. The pic is really grainy, but it shows that I was over the river, heading east. "Our" point is the sharp one pointing to the left (north). The bridge doesn't show up--apparently isn't in the data--but its two towers are shown as obstructions. The little white rectangles are airport flags.
The round gauge at lower right is an altimeter showing that I was at about 1000 feet. (The other is IAS--about 100 mph.)
I was about to descend--but because of the bright lights, I couldn't see the surface directly and felt uncomfortable about getting very low. The synthetic view was probably good enough that I could have gone down to 100 feet, or possibly even lower, but I didn't trust it that much. It doesn't show trees!
The iPhone can get much dimmer than the 740--dim enough that it doesn't blitz my night vision. The 740, however, won't go any dimmer than the sectional portion that you see here. I'm leaning on the developers to fix that, and I expect they will.

Ha! Carol just sent me this little iPhone video of my Searey heading right toward her over Tar Bay at night--see the May 06 posts just above. It's not much of a video on its own, but is sort of fun if you know what it's about. All you can see is a few lights and some reflections on the water. The landing lights go out so suddenly because I switched them off when I turned north and powered up to climb over the lift bridge.

I like how your steam gauges are lit as well! Nice setup. Fore Flight, which I use on my Ipad has a button that allows you to "invert
Chart Color" But it is pretty nifty cause it only inverts the light background of the sectional chart to black, so that all the airspace
lines, airports (blue & magenta), etc. stay their proper colors. But it really is nice at night since it is much dimmer on the eyes, but
you can keep it at a bright setting to see the markings.

Thanks for bringing that up, Jeff! I will remember to try that next time! Foreflight can do so many things, and I do not take full
advantage of the service.

Great fun , Don!
FYI for those flying with Foreflight and an iPad at night. I manually turn down the brightness on the iPad first. Then I adjust the
Foreflight brightness adjustment for fine tuning. Works like a charm...

Wayne, the iFly GPS inverts the background for vector charts, but not sectionals. Even so, there's a limit to how dim an LED display can go and still be extremely bright in daylight. Below some certain voltage LEDs abruptly quit producing light. So in a way it's unfortunate that the iFly 740 has probably the brightest display available ("1300 nits"). It's easily readable in bright, direct sunlight. The iOS version just has two modes, day and night, with different colors. The dimming is handled by the device, not the app, and the iPhone will dim essentially to zero. I've been discussing the dimness--or lack of it--with the developers. They're going to fiddle with the colors, but I don't think they'll be able to make a big difference to the night brightness. I have a plastic screen dimmer overlay to use in the future.

Very nicely done Don! Both the flying and the video. Enjoyed the lesson and the tour. Great job.
