i want to train my sun conure to fly outside

I have seen many examples of birds flying outside with their owners supervising, and i am on the fence about training my bird to fly outside and come back. My opinion is that i should treat my bird like a friend and not an inferior and i know once she can fly she will want to. My ideal pet bird would be able to fly around and when i say come after about an hour she will come and in that way get exercise and enrichment.

Now a question is would predators try and attack her if she stays close to me because in my experiance the cats and animals always stay away when im around, is that true with hawks?
