Ok. You're weird. :wink:

One of the nice things I've collected over the years is the combo Great Falls/Salt Lake sectional excerpt for central Idaho provided by MountainCanyonFlying in McCall. When I first was learning that area (pre-GPS and without Loran), it was annoying to mess with two different sectionals. The iPad has eliminated that problem--as long as it stays charged (learned the hard way that neither the cigar lighter usb adapter nor the LIon battery pack will provide much, if any, charge to my iPad.) I now have hardwired USB charging ports now, so the iPad stays pretty even as long as I keep some airflow on it to prevent overheating.

I still have the Payette NF map and use it to refresh on drainages and landmarks when I've been away for a while. I used to remember all of that stuff. :?

One thing I noticed a few weeks ago was that ship-to-ship ADS-B works remarkably well even down in the canyons. It doesn't capture everyone, but it's a nice supplement. I assume that the diddling of the GPS signal will trash that traffic information.

This is the second day of the planned testing. Has anyone noticed any gps signal loss or degradation so far?

Still using sectionals (North up). Not sure what this tablet thing is you refer to or how you can display any navigational data on a 1" phone.

Good tip, I've dealt with that issue for years, living where I do, and even at 85 MPH it seems like I'm always changing charts! Never heard of a combo chart before, I assume it's a one off thing by MCF? Good on them for thinking outside the box and taking things into their own hands.

Yep. It's an MCF thing. It doesn't cover everything, but is might nice flying out of McCall and Cascade. MCF has a lot of nice resources.

Sorry for the crappy resolution. I'm not a Tapatalk VIP. :? The chart covers from Atlanta in the south to Dixie in the north, and from McCall in the west to Castle Peak in the east. Not quite to the Bighorn Crags, and definitely not Challis or Salmon. Still handy, though.

I flew in Korea as a Forward Air Controller. No GPS in 1978. We flew in the area right below the DMZ with a 25 lb map bag of 1:50,000 maps. Have we gotten that lazy? The military is doing this to see what goes down when GPS goes out.

We used to fight ground battles with muzzle loaders too,
and artillery battles with black powder canons.
Aerial bombing was a stick of dynamite dropped out of a biplane.
IMHO GPS is one of the most significant forward leaps in aviation of my time.

I've got an "Idaho Aeronautical Chart" put out by the state of Idaho back in 2012.
Perfect for flying in that state.
More states should do something like this.

Re: GPS Outages in Southern Idaho/Northern Utah

We've got one like that here in Texas. It's a fairly large size map sheet to cover the whole state, and the scale is greater to keep the size "manageable" in use. As a result, there is less detail than a sectional, but a bit more than the old WAC charts. I imagine Alaska has the same size / scale challenge...

Re: GPS Outages in Southern Idaho/Northern Utah

Montana Aeronatics sells an aeronautical chart for Montana. With that and the Idaho chart, covers most of what I’m interested in.

I flew into Smiley Creek from Bozeman on Tuesday and back this morning, and no GPS hiccups, though I was early today. Starting to get a fair bit of smoke in central ID.
Most of the smoke is coming from the south and west, but I saw one new fire this AM that wasn’t there Tuesday. TFRs popping up.

I had a forty knot tailwind coming home.

Re: GPS Outages in Southern Idaho/Northern Utah

Best thing about these state charts is that they don't need charging. The scale is more WACish, but fine for the basics. I do like having TFRs on Foreflight, provided there's ADS-B reception to update. But I just steer well clear of any smoke column on the assumption that there's a TFR.
