You're example, which I didn't include all of, really only describes poor piloting, not an inherent hazard to straight-in approaches.
I do straight-in approaches fairly often, but I call at 10 miles, 5 miles, 3 miles, and final. If doing a straight-in would conflict with other traffic in the pattern, then I won't do the straight-in.
I think the straight-in approach is safer than all of the extra maneuvering in the airport environment that a typical 45-degree downwind entry can require in some cases. But that is predicated on everyone making callouts as required. IME the NORDO guys are doing who-knows-what so I think we all just have to dodge them.
Flyboy, you are inadvertently pointing out the problem. Yes, when someone comes straight in, enters the crosswind or whatever AS LONG AS THEY'RE MAKING RADIO CALLS, it's not really a problem. What I see out here in the boonies are things like I describe where someone doesn't have a radio, too lazy to use it, think it's unnecessary, etc. Maybe it's not even one of those as the problem instead they just assume that there will be no one in the sky around that airport except themselves.
You and the other posters have made excellent points for me to consider and learn from, but I suppose it's impossible to consider all scenarios. Also I expect that different airports have a different group of pilots going in and out of them.
I think the problem at my home airport is due to several issues:
It is a VERY lightly used airport so people just think there's no one around and they can do whatever they want without worry.
Because it's lightly used, students seem to come in and out, probably on training cross countries and they choose it because it has low traffic and a big runway for a boon dock airport.
The last reason is just something I can't understand. I did much of my early training at a busier airport that was also uncontrolled, but with three BIG runways. There was commonly lots of traffic, but everyone expected it so if they weren't entering the pattern in a textbook fashion they were calling their intentions quite dutifully.
In this thread, all these different ideas about how to deal with an uncontrolled airport, including my own possibly being misguided, is the problem. The traffic pattern and specific TPA is SUPPOSED to be done so that we know where to look for planes. With all the different ideas and procedures, it throws the textbook approach out the window.
I would recommend reading the portion of "The Killing Zone" that talks about mid airs at uncontrolled airports.
I hope no one thinks I'm lecturing here. I'm just a student who flies out of an uncontrolled airport and just a few days ago had an attention getting episode due to strange procedures on the part of the visiting pilot. I am learning a LOT from you guys about this issue and I appreciate it.
