Aeroplane (chiefly British) is a powered flying vehicle with fixed wings and a weight greater than that of the air it displaces.
In American English, the term "airplane" is more commonly used.
Fun fact: The word "aeroplane" comes from the French "aéroplane", which originates from the Greek "aēr" (air) and "planos" (wandering).
