Runway ID

"Lakeview Bill" wrote No...

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

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

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

I'm sure I read a reg quoted earlier in this thread, that you got to choose
going up or down, when it was --5.

Who posted that?

So why is it correct to round 045 down to 'runway 4' and 055 up to 'runway
6'?

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...

This thread prompted me to fire up my Summit Aviation CD and search for all
usages of "runway number." (The CD includes just about every piece of paper
issued by the FAA.) In all of their examples of radio transmissions, they
use two-digit runway numbers. Other references just use a parenthetical
(runway number) to indicate where the runway number belongs. There is not
one instance where a leading zero is called for.

The magnetic heading of Runway 5 is zero five zero.

The discussion of name versus direction reminds me of the discussion by
the Mad Hatter in Through the Looking Glass. It was used in a computer
class to exemplify the difference between something and its name.

The original poster got it right with his use of the phrase "Runway ID",
because it is, in fact, an ID based on a number, as opposed to some type
of
number.

What is the magnetic heading of Runway 5?

If someone is named "Fred", do you refer to them as "Zero Fred"?

The point is, we are dealing with a "name" which consists of a numeral,
as
opposed to an actual number.

The runway is NAMED Runway 5. Why would you prepend a zero to a NAME?

In all of their examples of radio transmissions, they
use two-digit runway numbers. There is not
one instance where a leading zero is called for.

Do you mean that all the examples happen to use runway numbers in the
range 10-36, and that they never happened to use runway numbers which
point northeast?

Convenient, no?

Strickly speaking the runway names are names and not headings. For
example at Denver, runway 16L is 170 degrees magnetic due to their
being a runway 17L and R already with the same magnetic heading.

As for the runway 8 or zero 8, it seems to be always written 8 and not
08, but I don't think it is a big error, though apparently some pilots
are being taught this way, because you do hear it.

The magnetic heading of Runway 5 is zero five zero.


The magnetic azimuth of Runway 5 could be significantly different than 050.
A runway with magnetic azimuth of 045 through 054 would normally be
designated Runway 5. But magnetic azimuth changes over time, and as I
recall the directives allow for a difference of six degrees before
redesignation and repainting are required. But that's not adhered to very
closely. The ATW airport diagram shows the azimuth of RWY 29 to be 297.9
degrees. Runway 7L at MKE had an azimuth of 053 degrees before it was
rebuilt some ten years ago or so, no doubt to prevent confusion with Runway
7R.

Not just to you Bill but..............when you are on short final to a
runway heading about 010 degrees does it have "1" or "01" painted on it?
