I used 500 ft because at 1,000 you can still fix it safely and try to salvage the approach. Below 500 ft you have to really be on it. They were at 100 ft a half mile out slow and not correcting. I may be a bigot but I have a reason to be if this is standard operating procedures for them. Either conform or don't come here. We don't fly like that. You shouldn't be allowed to. The United flight waiting for departure could have easily been destroyed because of their lack of airmanship. But I am a bigot so shouldn't have an opinion. Bye.
