RNP stands for which concept?

• A. Receiver-Transmitter Protocol
• B. Required Navigation Performance
• C. Required Navigation Procedure
• D. Remote Navigation Parameter

Answer: (B)

RNP stands for Required Navigation Performance. In aviation, this term describes the level of navigation accuracy, integrity, continuity, and availability needed to fly a specific route or procedure under Performance-Based Navigation. The aircraft’s onboard navigation system, along with crew procedures and monitoring, must meet the defined RNP value, meaning the aircraft stays within the intended path’s tolerance with alerting if it deviates. For example, an RNP value like 0.3 indicates a lateral navigation accuracy requirement within 0.3 nautical miles. This concept is about meeting a required performance level for navigation, not about a communications protocol or a fixed procedure. The other terms listed do not represent the standard meaning of RNP in aviation.
