Answer:
The statement "all aircraft are not airplanes" emphasizes that not every aircraft is an airplane. There are other types of aircraft, like helicopters, drones, and blimps, that don't fall under the specific definition of an airplane. So, while airplanes are a part of the broader aircraft category, they don't represent all types of aircraft out there.
Step-by-step explanation:
The relationship between "airplane" and "aircraft" is a bit like a Venn diagram. Let me break it down for you:
Aircraft: This is the broader term that encompasses any type of vehicle designed for flying in the air. It includes a wide range of vehicles, such as airplanes, helicopters, gliders, drones, blimps, and even some experimental flying machines.
Airplane: This is a specific type of aircraft. An airplane is a powered flying vehicle with fixed wings and a weight greater than that of the air it displaces. It's designed to generate lift through its wings' shape and propulsion from engines. Commercial airliners, private planes, and military fighter jets are all examples of airplanes.
So, when we say "all airplanes are aircraft," we mean that airplanes are a subset of the larger category of aircraft. In other words, every airplane is indeed a type of aircraft.
