While total loss of GPS navigation signal without warning remains a rare occurrence, it is not at all beyond the realm of possibility. When that time comes (without warning or as predicted by NOTAM), will you be ready? Have you studied or practiced navigating solely by use of VOR (or VOR/DME) lately? When was the last time you shot an old-school VOR approach without vertical guidance? Or thought about DME slant range error,
reverse sensing, or the VOR cone of silence? Can you still fly a DME Arc without any help from GPS distance information? Can you do it using a standard VOR Omni Bearing Selector (OBS), as well as via a Radio Magnetic Indicator (RMI) needle? Those skills are likely to be woefully
unpracticed and unused in the era of GPS. Yet, they are not skills we can simply allow to entirely escape our grasp. Grab your favorite flight instructor, saddle up your favorite training aircraft or simulator and go pretend it’s 1980-something. It will only seem like a futile exercise until your first GPS signal loss on an IMC flight to a LIFR airport. Then you’ll likely be thankful for the VOR MON and MONA networks, as well as your own commitment to stay proficient in all forms of navigation that your aircraft is equipped for. KA
