Definition
An FAA program that collects, measures, and reports the operational performance of facilities and equipment within the National Airspace System (NAS), including outages, interruptions, and reliability of navigation aids, radar, communications, and automation systems.
Plain English
A tracking system the FAA uses to monitor how well the equipment that runs U.S. airspace is working — recording when things break, how long they're out, and how reliable they are.
Context Anchor
You may encounter NAPRS after an ADS-B Out installation, after avionics maintenance, or when checking a reported equipment problem.
Why Pilots Care
When a navigation aid, radar, or communications facility is out of service, that outage flows through NAPRS and often shows up to pilots as a NOTAM. Knowing the system exists helps explain why outage information is consistent and trackable across the NAS.
Example Sentence 1
The VOR outage was logged in NAPRS, which is why a NOTAM was issued advising pilots the facility was unusable.
Example Sentence 2
NAPRS data helped planners adjust routes after seeing consistent congestion on certain airways.
