New data on IFR charts - MON

[jaylw314]

Hopefully, I'm not the last one to notice that on IFR charts, some airports and navaids are tagged with the letters "MON" in blue reverse highlight.  After some digging around, it turns out to stand for "Minimum Operating Network", and the FAA is highlighting certain facilities to have permanent radio navigation aids in case of GPS failure, so if you do lose GPS, you should be able to quickly find a MON facility on your IFR chart.

I believe that plan was to keep ground based navigation somewhere around 100mile range of each other. So that at anypoint of gps failure, any aircraft can make it to an airport with ifr reserves.

I hadn't noticed this before.  Thanks for pointing it out.

Thanks for pointing that out.... So you weren't the last to know

Thanks for the pic, I need to figure out how to clip images at some point

Not unsurprisingly, Garmins dynamic charts don’t show this...yet.
It’s interesting that VTA doesn’t have an ILS.

What are ‘dynamic charts’? Garmin Pilot is showing it for me:

This led me to skimming the FAA PBN document, seems by 2025 all ifr aircraft will be expected to be gps equipped

and by 2030 gps and dme/dme equipped.

That’s not the dynamic chart...that’s the IFR low chart.  I’d expect the IFR low chart to show all the updates.

the garmin dynamic chart is a different base layer you can select, which is an aggregate of highly configurable options.  One main advantage is that the labels will always be upright for you... where as with the base layer charts, they are static based on north.  I believe foreflight has a similar type of dynamic chart, too.

edit: I don’t use garmin’s app so if anything is not accurate in the above text, please feel free to jump in.

Ok thanks, I see which map he’s using now.

Say again?  For Part91 IFR?  DME/DME?!?

DME...you have a link to that document....I’m not buying that.

If the FAA was so concern about GPS they should have kept LORAN-C. There were Navigators with GPS/LORAN capability that would handle GPS failures seamlessly and continue RNAV navigation. After all LORAN-C was easier and cheaper to maintain than GPS, no rockets required but an SUV with a handy technician.

Thanks, the DME requirement is not for all of us, affects only the largest 75 airports. Is there for redundancy, for commercial/government aircraft.  If GPS goes offline, we can aways divert to a class D with ILS.

[tmo]

Oh. Just DME, not a DME/DME setup where two independent DME recievers track two distinct DME ground stations and determine location.

Something like this.

A single DME I don't have a problem with, lots of approaches this side of the pond require DME, and we do not have a blanket substitution with GNSS approval like the one the FAA gave for US airspace.
