ATM situation in AFI Region

• In the last 5/7 years, AFI Air Navigation
  Services Providers have carried out tremendous
  efforts to
• Improve communications services (fixed and
  mobile),
• VHF/VSAT networks (ASECNA, SADC, CAFSAT,..)
• NAFISAT project
• Migration on a common satellite
• Implement Air Traffic Control automation systems,
• Implement surveillance systems (secondary radars,
  ADS-B C)
• Develop Global Navigation Satellite System

Surveillance issues in AFI Region

• Lack of reliable surveillance
  mainly due to
• Difficulties or high cost of implementing/maintain
  ing SSR in remote areas,
• Traffic not sufficient to justify SSR coverage,
• Slow rate of new C,N S equipage,
• High cost of some C,N S equippage,
• Numerous old and analog A/C in regional fleets,
• Difficulties to secure scarce capital funds by
  ANS providers and airlines or aircraft operators

IATA position

• Extracts from IATA ATM Implementation Roadmap
  (2005)
• Surveillance is a fundamental enabler of ATM
• The partial or complete lack of adequate ground
  based surveillance is a major safety and capacity
  issue
• Mode S Secondary Surveillance Radar is supported
  where justified
• IATA encourages the development and
  implementation of automatic air ground position
  reporting, using inter alia, ADS and ADS-B ...

Conclusion about surveillance

• ADS-C
• Airlines should take benefit of ADS-C
• ADS-B
• is a valuable and cost effective solution for
  surveillance for AFI
• comes as a complement to existing ADS-C and
  radars
• Avionics is the key issue for successful ADS-B
  implementation
• RADAR
• traditional surveillance means must be
  implemented, pending for the availability of new
  technologies (ADS-B)

ICAO, AFI ANSP, IATA and regional airlines
representatives should develop a sound business
case regarding surveillance systems

Navigation

• Air Navigation in Africa (and worldwide) still
  relies on a costly network of ground based
  systems. This system has some limitations, thus
  explaining the growing trend to use Satellite
  based navigation (GPS)
• Since 1996, African States have recognized the
  benefits of using Space Based Satellite
  Augmentation systems, summarized as follows
• Improvements in safety by mitigating against the
  limitations of conventional navigation.
• Cost savings through less reliance on ground
  based systems.
• Cost savings by avoided diversions using APV I.
• Improved safety an enabler for future
  surveillance techniques ADS-C or ADS-B.
• Offer Multimodal capabilities

3 Regionals Projects

• Air Traffic Control
• Study the implementation of regional upper
  airspace centres for the management of the
  western and central Africa upper airspace
• Surveillance
• Improvement of the surveillance capability, by
  developing ADS-B capabilities
• Navigation
• Implement the GNSS satellite based augmentation
  system based upon EGNOS that will enable approach
  with vertical guidance (APV-I) capability to
  improve aviation safety and efficiency in a cost
  beneficial manner
