I suspect that Aves would have an entire subset of language for understanding aviation, similar to the extended vocabulary that high latitude cultures tend to have about snow:
The claim that Eskimo languages have an unusually large number of words for snow is a widespread idea based on the work by anthropologist Franz Boas and has become a cliché; it is often used to illustrate the way in which language embodies different local concerns in different parts of the world. Boas didn't make quantitative claims but rather pointed out that the Eskimo–Aleut languages have about the same number of distinct word roots referring to snow as English does, but the structure of these languages tends to allow more variety [emphasis mine] as to how those roots can be modified in forming a single word.
The significance of this is in the ability to express and share ideas. With a broader vocabulary, or more nuanced phrasings, as seems to be the case above, people have the ability to express more complex and subtle ideas. It is experience and practice plus thought on a subject matter that promotes these extensions to language. And likewise the extensions to the language promote deeper thought and clearer communication on the subject matter.
Similarly, weather knowledge can be thought of from an experiential perspective. Farmers who have lived and worked in the same area for a period of time can often look at the sky, feel the air and predict with greater accuracy the weather in their local area than meteorologists whose job it is to track and predict weather on larger scales than what concerns a local farmer.
Aves, also I suspect, would have visual knowledge of the sky, but unlike a farmer they would have a physical sense of the sky from up in the sky. They could fly through turbulent air, taste it, feel the intensity of it, whether it is large and flowing turbulence, less chaotic turbulent air, or smaller, roiling turbulence, hotter, colder, wetter, drier, charged, etcetera. There would likely be an entire area of language that farmers or perhaps even meteorologist do not possess to such an acute degree.
