In base form, Aerial Ace provides you with coverage against Grass types which resist Bolt Beak. It also never misses, which is good because of Hustle lowering accuracy. However, this is really unconvential because the only Grass type you'll be seeing in VGC 2020 is Amoonguss, and Rillaboom
Dynamax Max Airstream is more useful, since it also doesn't miss, boosts Dracozolt's speed to power-up Bolt Beak, is team support because of the fact that it also raises the ally's speed, and is much stronger and still covers grass types.
Conclusion: Aerial Ace can be considered, however if not running Dynamax you shouldn't really use it, since there are better coverage options like Low Kick, Earthquake, Outrage/Dragon Claw, etc...
Hope this helps :)
