Which ICAO initiative promotes the implementation of Performance-Based Navigation (PBN) to enhance flight efficiency, reduce fuel burn, and lower aviation's environmental footprint?
- Global Air Navigation Plan
- No Country Left Behind
- Aviation System Block Upgrades
- Carbon Offsetting Scheme
Answer: Global Air Navigation Plan
GANP provides a 15-year rolling framework for modernizing global air navigation. PBN, a key component, allows aircraft to fly optimal trajectories using satellite-based navigation, reducing delays, emissions, and noise while increasing airspace capacity and safety.
