Simulation of landings and take-offs at Lyon-Saint-Exupéry

At Lyon-Saint-Exupéry, precise simulations of South facing operations mixing planes arriving (in red, on the Easternmost runway) and planes leaving (in blue, on the Westernmost runway).
The messages appearing at the bottom in white correspond with the description of the radio interactions between air navigation and an aircraft during the time in which the message in question is displayed.
The indicators displayed enable us to view certain indicators enabling us to calibrate the models so that they are representative of real operations.
The simulation starts here at around six times the real speed.

Optimization ao departures at Lyon-Saint-Exupéry

The video evidences the savings on taxiing time permitted by an optimization of the aircraft block departure times as provided in the local management concepts for departures used for the implementation of an ACDM (airport collaborative decision making).

On the left, the aircraft leave their parking bay at the times “scheduled” in their scheduling.
On the right, based on their scheduling, the aircraft only leave their positions at the time necessary to get to the take-off runway and wait there for as short a time as possible.
The curves thus show, for the two cases, the “optimum” taxiing time in green, which is the theoretical time for aircraft if they were each taxiing alone in the airport, and the actual taxiing time in red, which is the measured taxiing time of aircraft when taxiing in a queue.
To this the accumulated fuel consumption curve is added.

Study of passengers screening checkpoints

The video illustrates the possibility of modelling the passenger inspection process in detail, from when they join a queue to when they exit the inspection lines.
The modellings provide a detailed analysis of the interactions of the different links of the process and enable the impacts that modifications of it may have to be evaluated: re-arrangement of the waiting queues, line use strategy, change of detection technologies, etc.
