Runway ID

Ah, because the REAL rounding rule, designed so that averages will not
become distorted high from rounding 1/2 up, is to round 1/2 to the
EVEN number.


If these runways were at the same field, your method would have runway
designators that differ by twenty degrees for runways that have a difference
in azimuth of only ten degrees. I think I'd round both in the direction
that local magnetic variation was moving.

True or false: An airplane can be a Piper or a Cessna.

While it is also true that an airplane could also be a Mooney or a
Beechcraft or any of the thousands of other builders that have come and
gone, the statement: "An airplane can be a Piper or a Cessna", is quite
true, although quite possibly less than necessarily inclusive.

Hence my choice of the absolutely true statement:

"The magnetic heading of Runway 5 can be any heading between 046 and 054."

I recognize that Runway 5 MIGHT also have a magnetic heading of 045 or 055.
But if it has a heading between 046 and 054, it WILL ABSOLUTELY be Runway 5.

My choice to use "between 046 and 054" instead of including 045 or 055 was
in the, obviously vain, hope that we could avoid the endless argument over
minutiae that all too often clogs this group...

No, Bill has this right. If rounded correctly, 045 becomes 'runway 4' and
055 becomes 'runway 6'.

Actually, it could be 045 to 055. There is a choice of rounding up or
down,
with a heading ending in "5".

KMKE had a runway some years ago with a magnetic azimuth of 053. It was
designated Runway 7L.
