Warmi,
I don't disagree about the value of communicating on ctaf. However, I couldn't disagree more about learning to be better at spotting traffic and/or critical obstacles etc.
My point, was that the we need to be the best we can be at operating in different types of airspace. Reality is that communication is not required in class E and G airspace, proceed accordingly.
That said, how often do you hear pilots calling from 10 west, when they are actually in some other direction? In my experience, it happens all the time. There are many days in central TX when there are so many aircraft reporting on 122.8, that it is downright absurd. There's always the one guy that wants to tell his life story every 30 seconds, instead of just reporting his position and clear/brief intentions; meanwhile he gets stepped on by the Skyhawk calling every leg of a closed pattern for an hour straight, along with the other Skyhawks doing the exact same thing at 12 different airports within 100 miles on the same ctaf. On top of that, Bill wants to BS with his buddy George, b/c there is no one in the world besides them, and they have never heard of using a discreet inner-flight frequency. The icing on the cake, are the ifr pilots reporting as though vfr pilots have a clue about what they are saying, which of course they don't.
So yeah, talk on the radio in uncontrolled airspace, but please strive to be the best you can be at using all those layers of safety.
The reason I don't talk a lot on the radio at work, is because there's a lot of different tasks/information I am juggling in the cockpit, we're also talking on our work radio. Combine that with flying between 5' AGL up to as high as 500' in turns, trying to be as efficient as possible; all whilst not hitting wires, towers, other low flying aircraft, and performing a quality application on target in constantly changing atmospheric conditions etc. In that scenario, it is usually a lot safer to focus on listening to traffic, and only speak when absolutely necessary. My life literally depends on see and avoid all day, every day at work. If it wasn't possible to get better at that, seriously doubt I'd still be alive.
In my personal aircraft, we always communicate within 10 miles of an uncontrolled airport. Also, I spent a ridiculous amount of money on all kinds of bright flashing lights!
