1.2. Research Questions

The main research question of the thesis is: Will ASECNA meet the needs of African Air Navigation for the 21st Century?

Responding to that question requires that the following intermediate questions are dealt with:

6 ASECNA region

7 Africa and Indian Ocean

1. What are the needs and the priorities of African Air Navigation for the 21st
century?

2. Are CNS/ATM systems the suitable tool with regard to regional characteristics?

3. Will ASECNA's modernisation strategy respond effectively to the needs?

1.3. Objectives

The objectives of the study are to:

1. Examine the state and the performance of air navigation service provision in

ASECNA

2. Study the potential benefits of CNS/ATM systems to the region

3. Analyse ASECNA's modernisation plans 1.4. Methodology

This research is based on an analytical approach to assessing ASECNA's capability to respond to airspace users' needs and requirements and regional air transport's interests. To answer to the first research question that aims at defining the needs and the priorities of African Air Navigation, we process as follows:

First, the region's air transport industry is assessed. This is done by examining local air transport characteristics:

1. Analysis of air travel demand

2. Assessment of air carriers types

3. Examination of air carriers performance

4. Examination of airport and alternative transport infrastructures

5. Overview of regulations and the factors that influence air traffic.

Secondly, the air navigation system's performance is studied, by analysing key performance areas and related indicators:

1. Traffic demand, Capacity, Delays

2. Complexity, Safety, Aircraft proximities

3. Performance of CNS and Met systems.

4. Fragmentation, Cost Effectiveness

5. Flight efficiency

6. Cooperation.

The analytical framework used is described in figure 1.2 below. The structure is based on a model developed by the Eurocontrol Performance Review Commission to assess European Air Traffic Management performance. It has been adapted for the present study.

Finally, the impact of traffic growth is estimated. We apply forecasted growth rates to current data, in this case 2003.

To answer to the second research question, which aims at determining the relevance of CSN/ATM systems in ASECNA, we adopt the following method:

Based on the system's deficiencies and local characteristics drawn from the previous performance analysis:

1. Identification of potentially suitable CNS/ATM technologies and systems based on FANS performance during worldwide trials. These trials are performed under certain geographic and operational conditions; some of them match ASECNA area's characteristics.

2. Their affordability is assessed At last, the third research question is dealt with as follows:

1. Assessment of the technology solutions adopted

2. Assessment of the implementation process, and we analyse the strategies in the areas listed below:

a. Communication

b. Navigation

c. Surveillance

d. Met

e. Air Traffic Management

f. Training

g. Programme financing

h. Cooperation

3. Assessment of the timeframe by confronting the predicted timetable and realized projects.

When quantifiable data are not available, interviews allow to have an idea of the situation. Interviewees are ASECNA's high profile staff, airlines directors, and other ANSPs' personnel.
