Cette page sert à afficher le nombre d'avions produits par chaque pays.
Objectif
Aujourd'hui, les constructeurs d'avions ne cessent de produire de nouveaux types d'avions (Boeing,Airbus ...), ces derniers peuvent varier selon la taille, le but (commercial, indistruel ...) et leur consommations. Cependant, cela impacte notre environnement écologique.
Le but principal de cette application est de montrer les pays qui ont produis le plus d'avions.
