    Bien que ne faisant pas directement partie de l’aéronautique à proprement parler, la société EURO-DIESEL entretient néanmoins des liens étroits avec le secteur. Le plus évident est probablement le rôle essentiel joué par son produit phare auprès d’un de ses clients les plus importants: les aéroports & tours de contrôle du trafic aérien. Le très haut degré de technicité de ce produit le rend également comparable aux technologies de l’aéronautique. Nous avons rencontré Philippe Gillain, administrateur délégué d’EURO-DIESEL, qui nous explique les spécificités de cette entreprise liégeoise, et les profils qui contribuent à sa réussite.
