SAFE TOWER

1
SAFE TOWER

• Modern Control Tower Consoles with VCCS, AWOS and
  DIVOS Recorder Successfully installed in Lagos,
  Abuja and Port Harcourt while Kano installation
  is pending till the construction of a new Control
  Tower is completed

2
Total VHF Coverage of the Airspace

• Project Background Rapidly increasing volume of
  air traffic in the airspace
• Objective To guarantee the safety of the flying
  public throughout the duration of every flight
• Status Contract awarded to Park Air Systems, UK

PROJECT SCOPE

• AIS
• AMHS
• AIP/MAP
• National Obstruction Database

6
TECHNOLOGY

• MF-TDMA VSAT Network
• Meshed topology
• Capable of providing fully redundant
  ATS-infrastructure

7
Installed Capacity

• AIS/AMHS/AFTN
• CNS/ATM APPLICATIONS
• 99.99 Reliability rate, greater than ICAO SARPs
  99.97

8
Other features

• Redundant VSAT systems comprising two complete
  VSAT systems operating in parallel via two
  different satellites
• Fully compliant with ICAO/EUROCONTROL standards

9
PROJECT IMPLEMENTATION

• Project to be implemented in two-stages due to
  budget constraints

10
Stage 1 Redundant fully meshed MF-TDMA SkyWAN
ATC VSAT-infrastructure with provisions for

• Radar
• ER-VHF (RCAG)
• AIS/AMHS/AFTN/MET networking
• Incorporating 12 sites as listed

• Lagos
• Kano
• Abuja
• Port Harcourt
• Maiduguri
• Sokoto
• Jos
• Yola
• Bebi-Osubi with ER Repeater for Kano ACC
• Kainji with ER Repeater for Kano ACC
• NEMA Search and Rescue Center, Abuja

11
Stage 2 Extension of redundant, fully meshed
MF-TDMA SkyWAN ATC VSAT infrastructure with
special provision for ATS-DS and AIS/AMHS/MET
incorporating 15 Airports

• Katsina
• Kaduna
• Zaria
• Minna
• Bauchi
• Akure
• Ibadan
• Benin

• Owerri
• Osubi
• Enugu
• Calabar
• Bonny
• Escravos
• Eket

12
Others features

• Spares
• Training
• On-the Job Technology Transfer

13
Alternative Sources of Power/Electromechanical
Systems

• Generators
• Solar Power
• UPS
• Inverters
• VAC Ventilation and Air Conditioning

14
Power Supply to Safety-Critical Air Navigation
Aids

• FAAN is vested with the statutory duties to
  provide power
• NAMA has been providing alternative power due to
  FAAN not meeting up with the challenge of power

15
Power Requirements

• Three Generators required for locations that
  solely depend on Generators
• Locations that have FAAN secondary power supply
  requires two Generators
• Locations that have primary power source from
  PHCN and secondary power from FAAN requires
  atleast one standby Generator
• In addition, all locations require appropriate
  UPS with surge protectors and other protective
  devices

16
Fuel Supply for Generators

• Consumption matrix based on fuel requirements for
  stations indicates that quarterly consumption of
  AGO and PMS is on the average of 28,000Ltr and
  27,000Ltr respectively
• The cost is implication of the above is enormous
• Budgetary provision should be made to support
  these requirements

17
HUMAN CAPITAL DEVELOPMENT

• ATSEP Licensing programme
• Rapid factory training on TRACON, Safe Tower and
  VSAT network embarked on in the last 3 years
• Over 70 engineers have been trained overseas on
  the various subsystems above
• Other overseas and local courses are embarked on
  annually based on budgetary provisions
• These trainings are capital intensive

18
Challenges and Constraints

• Due process and other procurement related delays
  leading to contract variation
• Clearing of goods at ports
• Logistics of managing multi-site projects
• Weak matrix project environment
• Power outage that affects CNS facilities leading
  to downtime and high cost of maintenance
• Keeping up with modern trends in the highly
  dynamic and technology driven aviation industry

19
Conclusion

• The trend worldwide is to run organizations that
  have the capacity to self-sustain however
  considering the decay and neglect of the past
  years, total support is required from the
  Government for us to attain this height in future
