Driving Economic RecoveryAviation’s Global Impacts Source: ATAG; ICAO $2.2 trillionContributed to global GDP annually 2.9 billionPassengers annually $5.3 trillionCargo by value annually

The Pace and Resilience of Modern Air Traffic Growth Global air traffic has doubled in size once every 15 years since 1977 and will continue to do so. This growth occurs despite broader recessionary cycles and helps illustrate how aviation investment can be a key factor supporting economic recovery. Source: Airbus

The ICAO Block Upgrades (blue columns) refer to the target availability timelines for a group of operational improvements (technologies and procedures) that will eventually realize a fully-harmonized global Air Navigation System. The technologies and procedures for each Block have been organized into unique ‘Modules’ (smaller white squares) which have been determined and cross-referenced based on the specific Performance Improvement Area they relate to. ICAO has produced the systems engineering for its Member States so that they need only consider and adopt the Modules appropriate to their operational need.

Bywayofexample,Block‘0’(2013)featuresModulescharacterizedbyoperationalimprovementswhichhavealreadybeendevelopedandimplementedinmanypartsoftheworldtoday.Itthereforehasanear‐termimplementationperiodof2013–2018,whereby2013referstotheavailabilityofallcomponentsofitsparticularperformanceModulesand2018thetargetimplementationdeadline.ItisnotthecasethatallStateswillneedtoimplementeveryModule,andICAOwillbeworkingwithitsMemberstohelpeachdetermineexactlywhichcapabilitiestheyshouldhaveinplacebasedontheiruniqueoperationalrequirements.
