Hmm! At first glance that conclusion seems counterintuitive, but I guess
you learn something new every day.

But leaving an event up to chance as the avoidance mechanism, is not
something that sits well with people. I have to feel that way, in that the
results of "winning" the odds are so dire.

Absolute agreement. To me, it's a good reason to be "heads up" when
flying over VORs, since they can really concentrate aircraft. Most
of us are spending more time on the gauges watching for the arrow to
change.

Still, maybe it's a non-issue, since we don't seem to hear of lots of
collisions around VORs. Seems like mid-airs are mostly around
airports. Anyone know the real stats of locations offhand?

Thanks, Kev

Never mind, I googled it myself, and here's a good summary from the
USAF:

1. Mid-air collisions generally occur during weekend daylight hours
56% of the accidents occurred in the afternoon.
32% of the accidents occurred in the morning.
2% of the accidents occurred at night, dusk, or dawn.
2. Most mid-air collisions occur under good visibility.
3. The majority of the aircraft involved in collisions are not on any
type of flight plan.
4. Nearly all accidents occur at or near uncontrolled airports and at
altitudes below 1000 ft.
5. Flight fatigue is not a major factor in most mid-air collisions.
6. The average flight time prior to the collision is 45 minutes. This
time varies from takeoff to over seven hours.
60% of the pilots on the mishap flight had been airborne thirty
minutes or less.
Only 6% had been flying longer than two hours.
7. Pilots of all experience levels are involved in mid-air collisions,
from the first solo ride to 20,000 hour veterans.

Because it requires more skill than just typing CTRL-ALT-DELETE you.

How and why would he type Ctrl-Alt-Del? Why not just steer the aircraft
to a
landing?

He was talking about you, you idiot. If you get in trouble with
your computer game, all you have to do is cancel the game. Sheesh, what a
numbskull you are.

It's probably just a question of numbers. It's much less likely that two
aircraft will pass over the same VOR at the same moment and the same altitude
than it is that two aircraft will aim for the same runway at the same time
from the same direction.

If traffic is precisely paced along airways, that could increase the risk, by
creating dangerous periods during which multiple aircraft might arrive at the
same spot at the same time.

Precise traffic control increases safety to the extent that you can control
and determine the exact position of all aircraft at the same time, but it also
diminishes safety to the extent that you _cannot_ do these things.

This implies that there's no one-size-fits-all for aviation traffic control
methods, which perhaps has significant implications for the industry, given
the periodic transition towards ever more accurate navigation methods
(unfortunately without a concomitant transition towards more accurate and
reliable anti-collision technologies).

What's the URL, and what else did they have to say about the problem?

You don't do that with Ctrl-Alt-Del. On Windows XP, this key sequence calls
up the task manager, which is normally not used to stop applications or
processes.

VORs? Who flies over VORs? GPS eliminated VOR in my vocabulary in 1993

I disagree in principle. "Pacing" would imply everyone maintaining a
fixed distance between them and going at the same speed. That doesn't
happen often in "real" aviation. I cruise toward the imaginary VOR at
75 MPH. United 405 may be at 550 MPH (granted I am at 500 feet and they
are at 34,500 feet)...but my friend behind me may be at 500 feet and 110
MPH, therefore I better be checkin' six.

Determine the exact position of each aircraft? Nope, I don't have a
transponder and unless ATC is using primary radar, they don't even know
I exist at that VOR.
