Parrot flight aviator?

I have an amazon parrot who screams alot, and had a parrot sales brochure come through today and seen the parrot harness and flight lines how easy is it to train a parrot to fly with the use of a harness as they sound great fun for me and Charlie and would be good exercise for him to keep him in good health. Also Thinking along the lines that if he has enough exercise which he probably doesnt get at the moment cause he can only fly around the house he may not scream as often. I dont want to pay out alot of money if they are not that good or hard to handle as he is not an ”obedient bird” he does exactly as he pleases most of the time do they need to be well trained to use one of these flight lines??
Dont get me wrong when i say hes not obedient im very right in this but i can handle him hes very tame (with me)
Wacky read the question properly!!!!!!!! He needs a harness so i can attatch him to a flight line and let him fly out in the open fields safely

A flight harness is good idea but if you can’t handle him easily, you’re not likely to get him into one. And not all birds will tolerate a harness – some will spend every minute in the harness attempting to get it off.

You need to work on your relationship with the bird. Rather than buying a flight harness, spend the money on The Companion Parrot Handbook by Sally Blanchard http://www.parrot-fever.com/_store/display_products.asp?prodID=ISBN+096712980X&MPID=gofr or Guide to a Well Behaved Parrot by Mattie Sue Athan http://www.amazon.com/Guide-Well-Behaved-Parrot-Mattie-Athan/dp/0764110306
