Nov 8, 2009 · Yes, the FAA has MON but you might be that poor sap who is stuck 100nm in ANY direction from a VOR or ILS approach. So we need to keep VORs or at the very least bring back LORAN. A system based on low power AM signals are harder to jam then a barely above the noise floor GPS signal.

Jul 30, 2018 · Does it have glide slope? If it's a 2nd NAV radio then foregoing it isn't that big a loss in today's IFR environment. In a pinch, I think one could get by in the VOR MON system with just a single NAV radio in case of a GPS outage. However, 2 would be nicer. Also, the 30day VOR checks are much easier with 2 NAV radios.

May 29, 2015 · To stir the pot even more, I think ILS will become like VOR MON in the future, with only a select few remaining. Click to expand... Then hopefully they will change 61.65(d)(2)(ii)(C) so as to not effectively require VOR, ILS and GPS approaches.

Nov 30, 2021 · For GA, we will still have 2/3 of the VOR still in service for enroute navigation and the service volume of the low altitude VOR's will be increased from 40 NM to 70 NM at 5000 feet above the VOR. There will also be MON airports that have conventional ILS or VOR approaches that have no dependency on GPS, DME, ADF, or RADAR located within 100 NM ...

Dec 29, 2013 · And there definitely was further review after the public comment period, many procedures were kept that were on the cancellation list. Such considerations as other nearby VOR approaches, training requirements and such were considered. This is only tangentially related to the VOR MON program, the reduction of actual VOR facilities across the U.S.

Mar 14, 2017 · The thing you should google is whether the VOR your asking about is part of the VOR minimum operational network (MON) which are the few VORs the FAA intend to maintain after nextgen becomes complete. If the VOR has been out for a while, it likely is scheduled to be fully decommissioned in phase 1 or 2 of the VOR MON program.

Apr 21, 2014 · Is there an official specification of which 24 VOR's will be the LEGACY ones ? Has this developed enough that any equipment/operational specifications will...

Feb 9, 2023 · For those aircraft that do not carry DME/DME, the FAA is retaining a limited network of VORs, called the VOR MON, to provide a basic conventional navigation service for operators to use if GNSS becomes unavailable. During a GNSS disruption, the MON will enable aircraft to navigate through the affected area or to a safe landing at a MON airport ...

Oct 16, 2019 · Actually, VOR MON can increase your need for more than one NAV radio. If you don't have a VOT or VOR checkpoint on your field (airborne checkpoints seem to have all but disappeared), then you're left with either a dual VOR check or …

Feb 29, 2008 · There is a reduction in the numbers of VOR, about a third, but the rest are not going away. The service volume is being increased as well at 5000 AGL from 40 NM to 70 NM. From every point in the NAS, there will be at least one airport within 100 NM that has approaches that only use VOR or ILS without any dependency on Radar, NDB, DME, or GPS.
