RVSM from Cabin Class

How tall is the airliner.. with the gear retracted.. lower engine cowls to
top of rudder..
150ft ft? 200ft?
Odds of getting "perfectly" over/under each other is marginal, so add the
slant range distance.
Plus allowable altimeter errors.

1000ft is pleanty of room.

We flew commercial back to Atlanta yesterday from California after a
weeklong trip to San Francisco, Napa, and Yosemite. On the way home, I
had
a window seat and was surprised on a couple of occasions at how close
1,000'
of vertical separation appears when you're looking out the window from
seat
13A. When another airliner passes 1,000' right under you on a reciprocal
heading with a closing speed of over 1,000 mph, it looks CLOSE.

It IS close. Compare 1000 feet with the actual dimensions of the
airliner, which are an appreciable fraction of the separation distance
for larger aircraft.

Even with gear extended, a 747-400 is 63 feet high--about 1/16 of the
separation distance. That's very roughly the relationship of one inch
to one foot, if you want to visualize it.

1000ft is pleanty of room.

I don't know that it's plenty, but with the right equipment, it's
sufficient.

so.. only 63ft tall.. and in your workds 1/16th the distance, so get the
point... 1000ft is pleanty,

And you are not a pilot so how do you know what is sufficient and what is
not.

There's nothing magic about being a pilot, and reasoning ability is
not the sole domain of the licensed pilot.

ahh... but there is somethign magical about being a pilot... and because you
are not you do not know that.
and as far as reasoning ability? one cannot reason, what one has not
experienced..

I've known a lot of smart people that were just not cut out to be in a
cockpit.

Sure you can; it's called "abstraction".

Because of my job I sit up in the cockpit all to often and watch the
TCAS alot. Flying into LA is tough sitting behind the pilot with no
control, but thank God go working equipment. Aircraft do seem close,
but they are not well not that close.

It always makes me smile to hear claims like that.

How do you "experience" 1000/63?

I've known a lot of smart people that were just not cut out to be in a
cockpit.

I've known a number of people who were licensed to be in a cockpit but
were not smart.
