jaylw314 Posted December 27, 2019 Report Share Posted December 27, 2019 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. https://www.faa.gov/about/office_org/headquarters_offices/ato/service_units/techops/navservices/transition_programs/vormon/ 2 2 Quote Link to comment Share on other sites More sharing options...

So that at anypoint of gps failure, any aircraft can make it to an airport with ifr reserves. Quote Link to comment Share on other sites More sharing options...

ArtVandelay Posted December 27, 2019 Report Share Posted December 27, 2019 Not unsurprisingly, Garmins dynamic charts don’t show this...yet. It’s interesting that VTA doesn’t have an ILS.Tom Quote Link to comment Share on other sites More sharing options...

McMooney Posted December 27, 2019 Report Share Posted December 27, 2019 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. 1 Quote Link to comment Share on other sites More sharing options...

Garmin Pilot is showing it for me: 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.

Gagarin Posted December 27, 2019 Report Share Posted December 27, 2019 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. 2 Quote Link to comment Share on other sites More sharing options...

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. 2 Quote Link to comment Share on other sites More sharing options...
tmo Posted December 28, 2019 Report Share Posted December 28, 2019 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.
