Why is the working capital of the aviation industry negative? Please explain! Come on, come on, come on.

Working capital in a narrow sense refers to current capital-current liabilities. Enterprises have a large number of current liabilities due to the existence of a large number of accounts receivable and necessary inventory.

There is hardly a large amount of accounts receivable in the aviation industry, and a large amount of cash will be converted into bank deposits in the course of operation, just like the retail industry, with negative working capital.
