The wider implementation of performance-based navigation (PBN) should be global aviation's top navigational priority, according to the International Civil Aviation Organisation.
Speaking at ICAO's four-day PBN symposium at its Montreal headquarters on 22 October, Nancy Graham, director of ICAO's Air Navigation Bureau, said: "PBN implementation is the global aviation community's highest air navigation priority, It is a key building block for airspace improvements and a framework that leverages the full capabilities of existing technologies.
"This symposium has reinforced the already good stakeholder collaboration that we're seeing in this area, and maintains the sector-wide focus we've been driving on delivering clear, measurable results."
PBN is a form of area navigation that can deliver three-dimensional airport approach and departure paths, usually employing satellite navigation system signals, the degree of accuracy dependent on the capability and integrity of onboard equipment, and the quality of satellite signals and augmentation systems.
Graham added: "The new PBN manual and a wide range of additional supporting documentation were provided to symposium participants in a new PBN iKit, or implementation kit. These are USB-based and feature an interactive HTML 5.0 interface that lets each type of PBN specialist find the documentation and other ICAO resources specifically applicable to their area."
ICAO announced it has endorsed five independent instrument procedure design organisations "to provide Member States with greater confidence when seeking external support on implementing PBN capabilities".
