Learner Survey: Feedback on Module 6 PBN Content

Master the essentials of modern Performance-Based Navigation (PBN) and confidently apply RNAV and RNP fundamentals in day-to-day air traffic control operations. This concise, controller-focused course demystifies how contemporary avionics, flight management systems, and navigation specifications translate into safer, more efficient, and more predictable traffic flows. You’ll start with Area Navigation (RNAV) concepts—including LNAV and VNAV behavior—so you can anticipate aircraft trajectories and reduce tactical workload. Then, you’ll step into the PBN framework to understand the difference between RNAV and RNP, the role of on-board performance monitoring and alerting, and how navigation specifications shape airspace and procedure design. Finally, you’ll connect the dots with practical applications like RNAV-5 en-route and RNAV-1 terminal procedures, including spacing, sequencing, conformance monitoring, and what to do when performance can’t be met. Built around real ATC scenarios, quick checks, and a consolidated review, this course equips you with clear mental models and phraseology awareness to coordinate effectively with pilots and adjacent units. If you’re looking to boost capacity, predictability, and safety in a PBN-enabled environment, this course provides the operational insight you need—without unnecessary technical overload.

            <p>Performance-Based Navigation: RNAV, RNP, and PBN Fundamentals equips basic-level air traffic controllers with the core concepts, terminology, and operational perspective needed to manage today’s performance-based airspace. The module begins by framing PBN as a modern navigation framework that enhances efficiency, capacity, predictability, safety, and global interoperability. From the ATC vantage point, understanding how aircraft achieve lateral and vertical guidance—whether through RNAV capabilities or RNP with on‑board performance monitoring and alerting—directly informs route design, sector throughput, conformance monitoring, and contingency management. Throughout the course, the emphasis remains on how these navigation methods translate into more direct routings, improved trajectory predictability, and harmonized procedures that support standardized separation and optimized flows.</p>

<p>Lesson 6.1 establishes the principles of Area Navigation (RNAV) and the role of the Flight Management System in integrating positioning sources such as VOR/DME, DME/DME, INS/IRS, and GNSS. Controllers are introduced to LNAV for lateral path tracking and VNAV for vertical profile management, with a focus on how these functions shape expected aircraft paths and timing. Lesson 6.2 builds on this by defining the PBN framework and distinguishing RNAV from RNP, highlighting the added value of on‑board performance monitoring for route assurance and alerting. Lesson 6.3 narrows to common navigation specifications relevant to ATC—RNAV‑5 for en‑route and RNAV‑1 for terminal operations—linking accuracy requirements to route spacing, sequencing, and response when performance is not met. The integrated review concludes with scenario-based application, phraseology and capability confirmation, and controller actions when navigation alerts occur, consolidating the benefits of PBN in daily operations and preparing learners for knowledge checks and feedback.</p>
