There is an error in the spanish language:
While in-air with jets, there is an opption called ("Gear Up") which in-game is translated to ("Subir marcha") , but Marcha is NOT the word for that case, as Gear for the Spanish is known (In the cases of the planes) like "Tren" that is an abrevation from "Tren de aterrizaje" Sooo To us "Gear up" is translated by us like "Tren arriba" and gear down is "Tren abajo".
I hope you fix it, becouse it's annoying to "March Up" .
