You're entitled to your opinion. Obviously you have a problem with airways, or
at least you have since I suggested one.

I see airways as providing guaranteed levels of obstacle clearance and navaid
reception. Routing is simplified by following pre-established airways as
opposed to making every flight one of a kind.

In the VOR world, the ambiguity's in VOR accuracy spreads people laterally
across a Victor airway.

In the GPS world, the accuracy of GPS puts everyone right down the center
line of a Victor airway.

Which situation is intrinsically safer as you near a VOR?

If you cannot be bothered to see and avoid or use radar flight following, you
can navigate by VOR and benefit from the inaccuracy to which you allude.

You'll have the same problem with GPS when navigating anywhere, including to
arbitrary published waypoints.

On an airway, you know that if you maintain a certain altitude, you won't hit
any obstacles or terrain. Off-airway, you have to try to determine that from
low-resolution charts, for your entire route.

Which situation is intrinsically safer as you navigate alone in your little
airplane?

How many midair collisions have occurred along airways and at VORs thus far?
How many instances of controlled flight into terrain have occurred off
airways?

Let's be honest: The only reason you have a problem with flying along an
airway is that I suggested it. If I had suggested direct GPS, you'd have a
field day with that, especially if I suggested flying through restricted
areas. But your real objective is to try and invalidate whatever I say,
whether it makes sense or not. And it irritates you all the more when what I'm
saying makes sense.

The thing is, I almost always make sense, because I research and study and
look things up, instead of inventing things off the top of my head. I just
repeat what authoritative and reliable sources provide, which pretty much
guarantees that I'll always be right. If you were able to separate the message
from the messenger, you would understand this.

Obviously you don't really know how to read a Sectional and you have to
determine the minimum safe altitude from the Sectional whether you are on
or off of a Victor airway.

Enough that there have been several articles about the subject.

Nope, the problem I have is you seeme to be convinced that using a Victor
airway has some magical properties that guarantee's safety.

The minimum safe altitude for an airway isn't necessarily the same as the
maximum elevation figure for the quadrant on the sectional. Furthermore,
OROCAs on IFR charts are still different (with a more generous buffer).

Enough that there have been several articles about the subject.

Can you point me to some of them?

Google.
