Transforming National Airspace through Performance-Based Navigation: Leadership and Lessons from Nigeria's Regulatory Transition

Performance-Based Navigation (PBN) represents a global shift in aviation, mandating transitions from ground-based aids to satellite-guided flight procedures. This study examines Nigeria’s PBN implementation as a case of public sector leadership driving airspace modernization. Background: The International Civil Aviation Organization (ICAO) urged all states to develop PBN plans by 2009 and implement satellite-based routes and approach procedures by 2016. Many African countries struggled to meet these targets, but Nigeria’s regulators endeavored to align with global standards. Objective: To analyze how leadership and regulatory actions in Nigeria facilitated PBN adoption, and what lessons emerge for similar transitions. Methods: A qualitative case study approach was used, drawing on official documents, ICAO reports, and stakeholder interviews. Data from Nigerian Civil Aviation Authority (NCAA), Nigerian Airspace Management Agency (NAMA), and international organizations were thematically analyzed using Kotter’s change model as an interpretive framework. Results: Nigeria’s PBN transition proceeded in phases: initial planning (2007–2010), phased implementation at major airports (2012), nationwide rollout (2013–2018), and continuous improvements (e.g. free-route airspace by 2021).
