Etymology: "Aircrews" is the plural of "aircrew", a noun for the people who fly and operate an aircraft. The singular is a compound of "air" and "crew", the second element meaning a group of people working together on a single task, here a flight. Both parts are plain English words, so the compound needs little explanation beyond its meaning: a crew that works in the air. The plural simply applies the usual English rule of adding an "s" to count more than one crew.
