Definition
In RNAV and RNP operations, the minimum navigation performance standards an aircraft and its avionics must meet to fly a particular route, procedure, or airspace. These standards specify the required level of accuracy, integrity, continuity, and availability of the navigation system, and may also include functional capabilities such as required equipment, crew procedures, and operational approvals.
Plain English
The set rules for how accurate and reliable an aircraft's navigation system must be before it is allowed to fly a specific route or approach. If the aircraft cannot meet those rules, it cannot use that route.
Context Anchor
Seen in discussions of instrument procedures, cockpit equipment databases, and the pilot’s responsibility to use current, approved information.
Why Pilots Care
Ensures procedures can be flown without unexpected navigation errors or safety risks.
Intuition Check
Do not read “quality requirements” as a general preference for something being “high quality.” In this context, it means specific standards the data must meet before it is acceptable for flight use.
Example Sentence 1
Before filing the RNP approach, the crew confirmed the aircraft met the quality requirements published for that procedure.
Example Sentence 2
Meeting quality requirements allows the pilot to trust the navigation fixes shown on the chart.
