I know the basic use for adverbs, but I found this sentence

> 飛行機が飛ばなくなると、地方の経済が悪くなるかもしれません

and I just don't understand the く in 飛ぶ.

question
reading-comprehension
What are some different uses of く?
You can think of it essentially the same way as with adjectives. The base word
is simply 飛ばない which conjugates the way an イ-adj does. So 飛ばなくなる means "become
such that they don't fly", or more simply "stop flying".

> 飛行機が飛ばなくなると、地方の経済が悪くなるかもしれません → If the plane(s) stop flying, the local
> economy may take a turn for the worse.
