Basic RNAV (B-RNAV) requires a track-keeping accuracy of?

• A. +/- 5 NM or better for 95% of the flight time.
• B. +/- 3 NM or better for 90% of the flight time.
• C. +/- 2 NM or better for 75% of the flight time.
• D. +/- 5 NM or better throughout the flight.

Answer: (A)

Basic RNAV (B-RNAV) is a navigation specification that mandates a specific level of navigation accuracy to ensure safe and efficient operation within certain airspace. The requirement for B-RNAV specifies a track-keeping accuracy of +/- 5 nautical miles or better for 95% of the flight time. This accuracy standard is crucial for effective airspace management, route planning, and the safety of aircraft operations, particularly in congested or controlled airspace. The 95% compliance criterion indicates that for the majority of the flight, a B-RNAV equipped aircraft must maintain the specified accuracy, allowing for a small margin of error that maintains safety and operational standards. In the context of other options, while they may reflect varying levels of accuracy and compliance, none meet the specific requirements laid out for Basic RNAV operations. Options reflecting stricter or less stringent accuracy requirements do not align with the established guidelines for B-RNAV. Thus, the chosen answer appropriately captures the necessary standard for track-keeping accuracy in this navigation framework.
