Grand Canyon Corridors

[DJ Todd B]

Does anyone know or recall if the GPS shows the Grand Canyon Corridors on the GPS Sectional chart AT ALTITUDE?  I am planning a trip and i would have expected these corridors to be clearly marked on the GPS Sectionals but it's not.  I remember seeing them last October during the CTLS Fly-in but I was at 11,000 feet and they showed up clearly.  Any thoughts or ideas?

I will be using the most western corridor for this trip.  I was using my I-FLY GPS unit to plan the trip but these corridors are not marked.  You would think that if it was that important, it would be clearly marked.  I used the same APP on my Tablet for the CTLS trip last year and it showed us in the corridor but not now so I am thinking it only displays itself while at attitude.  Not likely, but that's all I can figure out at this point.  Even if i go to SKYVECTOR which uses a "REAL" Sectional, NO corridors are shown. Curious as to "WHY" that is?

If I-FLY is similar to ForeFlight on iPad, the additional detail only shows up when you zoom in on the screen, like with the Terminal Area Charts.

Not sure about the why the GPS doesn't show, but Foreflight on both the iPad and Desktop/PC will show the corridors (as JLang indicated) when you zoom in.)  I've not tried I-Fly GPS, but am downloading now.  However I've posted a screen capture in case you need the information now for the western-most corridor.

Yeah, I saw this.  I just wish it was displayed on my I-FLY GPS so I could just accurately / pictorially enter it into my flight plan..

Thanks!

[DJ Todd B]

Thanks J LANG, that was the fix I was looking for.  I KNEW I had seen the corridor on the GPS Before!

I downloaded I-Fly GPS and, as JLang stated, you can see the corridor when zoomed in.  It takes a bit more zoom to see these corridors than on ForeFlight though.  Here’s a screenshot.

On Skyvector, if you locate over the Grand Canyon it will show a button in the upper right for the Grand Canyon VFR chart which shows the same stuff as the figure above here in Foreflight.  Cheers.

I fly allows you to pick the chart you want to use too. It's this button:  along the lower left side in the image provided by rtk above.

Normally, iFly picks the chart that makes the most sense for the zoom setting you have selected. If you are zoomed way out it picks the World Aeronautic Chart (WAC - 1:1,000,000 scale). If you are zoomed way in it chooses the Terminal Area Chart (TAC - 1:250.000 scale). In between. of course. It picks sectional charts (1:500,000 scale). This insures the text is not too small to read or absurdly large.

But to a limited degree, it also allows you to override its selection. That's where the chart selection button shown above comes in. This button also allows you to see the legends on the charts, if desired, or the VFR routing on the back of some terminal area charts.

Note that the Grand Canyon Special Flight Rules Area chart is labeled as a TAC chart even though it does not include a class Bravo air terminal. It just happens to be the same scale so iFly calls it a TAC for convenience.

You can order the paper grand canyon chart from Sporty's.  WF

it actually shows up on the IFLY GPS if you ZOOM in pretty tight.
