Thats fine, you can do that in aircraft up to BAe146. Unfortunately you can't do that sort of flying into busy controlled airports in a big jet. There's too much traffic and the aircraft isn't manouvreable enough. Try turning final at 400 ft in a 747 and you'd better have it right first time because there's no time to correct if you haven't. So what can we do to enhance safety when that sort of flying isn't available? Stabilised approaches are a proven way to reduce accident rates. If you get it right you should never get below 500 feet without being in the slot, and you should certainly have your approach (and hence workload) under control before you go below 1000 feet. If the introduction of stabilised approaches caused an increase in landing accidents I'd be more inclined to look at the training standards and the level of consistency in the flying. Maybe some previous dubious approaches had been masked by some extreme hand flying, undesirably high/low rates of descent or excessive manouvering on final? If applying more conservative approach criteria leads to an increase in accidents you've got to wonder what was being masked when people had carte blanche to do what they liked.
