> The FAA's network of Distance Measuring Equipment (DME) NAVAIDs will provide a PBN-capable† backup to GPS; however, for aircraft without scanning DME receivers (DD) or DD with Inertial Reference Unit aiding (DDI) equipment, the FAA will provide a conventional navigation backup service based on the VOR MON. The VOR MON is designed to enable aircraft, having lost GPS service, to revert to conventional navigation procedures.
