There's no mention of when tests might start, although that's likely contingent on when the companies can produce functional prototypes.

The move comes at a key moment for Airbus and Audi. Uber is ramping up its flying taxi development with a research center in Paris, putting pressure on its German rivals to step up their game. They're clearly doing just that. Even if it takes a long time before the machines reach the skies, this shows that they're committed to making their project a practical reality. And that, in turn, increases the chances that you'll one day hail a flying taxi to speed up your commute.
