[Ant-Man] If Ant-Man falls from a plane when he's really high up and the size of an ant and he turns normal size right before he hits the ground, could he survive?

My friend asked this because ants are able to survive falls because their terminal velocity doesn't get fast enough to be fatal to them.

A small ant's terminal velocity is around 4 mph. He should be fine so long as, when small, he has the mass of an ant and not his full human mass.

Something the size of an ant with the mass of a human would have a greater terminal velocity than a normal human, so he would not be happy if that's the case.

It seems that he has some control as to whether his mass decreases or not when he shrinks, so he just needs to make sure it does.
