Runway ID

You would choose the number to which the magnetic variation is taking
the runway. For example around the western US you would choose the
higher number as if you don't you'll have to renumber the runway that
much sooner.

What??? You don't rename a runway after it has been named.

The reg has been quoted. Show me where it says you have to take the
movement of magnetic variation into account.

I have seen many runways get renumbered after enough years of slow
change in the mag heading. Daytona Beach is an example that I can
quickly remember. Runway 7 used to be runway 6 about 20 years ago.

"On a single runway, dual parallel runways and triple parallel runways, the
designation number is the whole number nearest one-tenth of the magnetic
azimuth when viewed from the direction of approach."

Crystal airport (MIC) in Minneapolis area went from runways 4/22 to
6/24 a few years ago. I don't know why so much change though.......

I have a MIC airport diagram dated 97310. The present runway 6L/24R was
then 5L/23R. The present runway 6R/24L was then 5R/23L. There has been no
change in the magnetic azimuth of these runways. The magnetic azimuth of
runway 6L/24R is 050.6/230.6, as it was eight years ago. The magnetic
azimuth of runway 6R/24L is 050.7/230.7, as it was eight years ago. The
local variation on these charts is 2.6E, a January 1995 value. Why were
these runways redesignated?

Are there other runways in the area with a 5/23 designation?

Not at MIC.

Roger that.

What was being discussed, was -renaming- a runway, due to the -changing-
magnetic variation.

Yes, that's what I addressed. It says, "the designation number is the whole
number nearest one-tenth of the magnetic azimuth". It offers no exceptions.

You most certainly do. Our parallel runways here at BIL were renumbered
from 27 R+L to 28 R+L several years ago. They did this at the same time
they rotated the VOR for the same reason. Another example is MSP. The
parallel runways there were 11/29 until a few years ago when they were
renumbered to 12/30
