Our software solution comprises two toolsets, one (denoted ONETRAJ) for individual trajectories
of
aircraft, and the second one (denoted MULTITRAJ) for addressing issues between multiple
aircraft trajectories. Instead of presenting these two toolsets, we prefer to detail the back
end
of these software: the successive layers of software and algorithms. Once again, we believe that our
global
methodology is applicable to other fields than Civil Aviation, this is why we highlight it with some
level of detail.
The reader only interested by the applicability can just survey the Figures (digging into the animations
if
he wants some deeper understanding).
In order to optimize air operations, we complete the following tasks. Firstly, we identify where
the
aircraft profiles have been sub optimal with regards to their performance, and secondly, we
investigate why air traffic controllers have instructed pilots to do so. For these
two
activities, the keyword is pattern identification. These patterns are structured in
layers, from lowest to top, as illustrated on the left Figure. Our software solution
addresses each of these five layers with dedicated algorithms. This is
detailed in the following pages:
- Patterns from bottom layers (maneuvers, controllers'Instructions) ;
- Lower layer patterns (performance) ;
- Intermediate layer patterns (Alternative Scenarios) ;
- Top layer patterns (Controllers' workload, operational risk) .
