I don't believe they are certified for aerial targets. We've been doing ack-ack for 80 years and it is still a tough challenge for the professionals. When you shoot ducks or grouse you have a shotgun to make up for the fact that they move and you do not have good aim. Shotguns are useless against aerial targets that are too far away. This is more on the level of shooting a needle at a golf ball at the other end of your living room.
That's what rangefinders and ballistics software are good for..
