Transcripts
Avec 700 atterrissages et décollages par jour,
la tour de contrôle est le centre névralgique d'Orly.
Au moindre dysfonctionnement, c'est l'aéroport qui ferme.
Impossible sans elle de sécuriser le trafic aérien.
- Une tour de contrôle, c'est comme une aérogare, ça vieillit.
Les équipements à l'intérieur de la tour ont besoin d'être régulièrement rénovés, modernisés.
50 mètres de haut et une forme reconnaissable entre toutes,
la tour de contrôle d'Orly avait besoin d'être intégralement repensée.
En novembre 2017, l'aéroport va vivre une des périodes les plus sensibles de son existence.
Car comment moderniser la tour de contrôle sans affecter le trafic ?
Voici l'espace à rénover.
Depuis les années 60, c'est ici que les contrôleurs visualisent le ballet aérien.
50 mètres, carré ultra bruyant, entouré d'une immense baie vitrée
que l'on appelle dans le jargon la vigie.
Pour ne pas interrompre l'activité de l'aéroport,
il faut créer une salle de contrôle provisoire un étage plus bas.
Problème l'espace n'est pas adapté.
- Il a fallu modifier l'aspect extérieur de la tour de contrôle
pour créer des espaces vitrés aux niveaux qui se trouvent sous la vigie.
Rapidement, les anciens hublots sont remplacés par des grandes baies vitrées
afin d'augmenter le champ de vision des contrôleurs aériens.
Mais la plus grande difficulté est de basculer l'intégralité des systèmes radar,
GPS et radio sans que le contrôle aérien en pâtisse.
- Réaliser un tel basculement, on peut se dire il n'y a qu'à débrancher, rebrancher,
c'est plus complexe que ça car il faut pouvoir garantir la sécurité.
Il faut pouvoir aussi garantir la continuité et la régularité des vols.
On ne peut pas se permettre le matin à 6 h dire ça ne marche pas, on n'ouvre pas.
Après plusieurs nuits de tests et d'aménagements,
le basculement est réalisé et les contrôleurs s'installent dans cette vigie provisoire.
À l'étage du dessus, peut démarrer la rénovation de la salle de contrôle devenue obsolète.
Un chantier de jour comme de nuit, profitant au maximum de la fermeture d'Orly
de 23 h 30 à 6 h du matin.
- Ça a été un chantier complexe car il y avait toutes les contraintes réunies
dans un petit espace.
- Il y avait des contraintes techniques, des contraintes temporelles, de réalisation,
des contraintes d'accès car il a fallu monter 30 tonnes de matériaux à 45 mètres de haut
et pouvoir en évacuer autant.
Le tour de force est d'autant plus grand que le chantier ne doit pas
mettre en péril la sécurité aérienne.
- Une de nos principales craintes était de couper un de ces câbles radio
qui sont très importants pour nous.
Si ces câbles avaient été coupés, ça aurait pu compromettre
l'ouverture du terrain le matin à 6 h.
Durant quatre mois, la vigie fait peau neuve et intègre toute la technologie moderne,
à commencer par des plafonds isolant phonique qui sont installés
pour offrir aux contrôleurs plus de confort de travail.
Dans l'ancienne vigie, il y avait beaucoup de réverbération
et les contrôleurs s'entendaient les uns les autres.
Avec la nouvelle vigie, nous avons maîtrisé les flux sonores.
En conséquence, la sécurité des échanges avec les avions est bien meilleure
puisqu'il n'y a pas de risque de perturbation les uns avec les autres
et ça améliore la concentration.
De nouveaux postes de travail sont créés, entièrement numérisés,
ils permettront de traiter la totalité des données d'un vol, identification des appareils,
trajectoire, altitude ou provenance.
L'objectif était de pouvoir doter les contrôleurs d'un espace de travail
plus adapté aux nouveaux besoins et puis se préparer à l'arrivée des nouveaux systèmes
du contrôle aérien par un système plus intégré qui va permettre de numériser
dès le début de la vie du vol l'ensemble des informations.
Pour optimiser cette rénovation, les ingénieurs ont utilisé une technologie virtuelle,
la même que celle des jeux vidéo.
Chaque contrôleur a ainsi pu tester son futur environnement de travail.
On a modélisé numériquement toute la vigie avec des casques 3D.
On a immergé les contrôleurs le plus tôt possible dans leur futur environnement de travail
et détecter en amont s'il y avait des points qui pouvaient poser problème
et les corriger très tôt.
