Navigation Programs - NextGen DME

DME - Distance Measuring Equipment

What is the NextGen DME Program?

The NextGen DME program will expand DME coverage in the en route and terminal domains to provide resilient complementary system to support PBN operations in the event of a GNSS disruption without the need for an IRU.

Why is the NextGen DME Program Important?

As PBN operations are expanded, the ground-based infrastructure including facilities and conventional instrument flight procedures will be reduced. The FAA has established teams to work across lines of business to rationalize the legacy ground-based infrastructure to ensure the necessary safety backup capability will always be maintained.
