Default Runway Numbering - Radio Procedure

If you hear 'runway zero', then you know you have missed something in the
transmission.

If one announces "Runway Two Zero" but the "Zero" is cutoff the

this possibility.


...but it introduces the possibility of the listener hearing "runway

zero".
How is that any better?

It's best to use the numbers painted on the runway.

Similarly, if you're in the pattern for runway 20 and you hear somebody
announce "[your airport] traffic, N123 base, runway 2[garbled]", you can
assume you've missed something. You still haven't made a case for using
anything but the numbers painted on the runway.

Well, yes, the case is easy to make.

If everybody used the leading zero all the time, then you KNOW FOR SURE
anytime you hear less than two digits, then you have missed something.

If the leading zero is NOT used and you hear only ONE digit, then you have
no way of knowing whether you missed something, or not.

Shortening a direction-based entity in this way is unnatural and causes
confusion. Even the FAA's own NACO chart-selection web site, uses the
leading zeros in the index, and then omits them on the charts..

How do I know the digits haven't been transposed? If I hear, "Podunk
traffic, Waco niner eight zero one victor, entering downwind runway zero
two, stop-and-go, Podunk", how do I know the pilot didn't mean to say,
"Podunk traffic, Waco niner eight zero one victor, entering downwind runway
two zero, stop-and-go, Podunk." Podunk does have a runway two zero, but it
has no runway designated zero two.

What might I have missed if I hear,"Podunk traffic, Waco niner eight zero
one victor, entering downwind runway two, stop-and-go, Podunk."

That may be only a software requirement.

"Podunk traffic, Waco niner eight zero one victor, entering downwind
runway two ZERO, stop-and-go, Podunk."

He's actually coming the other way, head on to you who hears "runway
two, stop and go..."

How do I know the digits haven't been transposed?


I suppose you don't, and that's the argument for omitting the leading
zero. Further, you could hear it correctly and transpose it in your own
mind.

Which one trumps the other? I don't think either is trump. Do what
other pilots expect to hear, whether by local practice or AIM.

Nope, there wasn't enough room between "runway" and "stop" for "two zero".
He definitely said "downwind runway two, stop-and-go". There was no zero.

Non-use of the leading zero trumps the use of it, no question about it.

Note that all of the scenarios used to support the use of the leading zero
rely on improper phraseology. If proper phraseology is used the leading
zero provides nothing positive, but if it is used it creates the possibility
for confusion as it can be transposed with the other digit. That
possibility is not limited to runway 2/20 either, as the field may have an
intersecting runway it could be confused with, such as runways 1/19 an
10/28.

Bottom line, the leading zero should not be used.

Yes, but =she= (the next week) spoke slower, and with a more varied cadence.

Well, the discussion here shows that there =is= some question about it,
just not in your mind. I tend to agree with you that non-use is
probably better. However, it is not without benefit.

As for being nonstandard, that's just a matter of changing the standard.
Elsewhere they use a different standard, but the laws of physics are
the same.

That
possibility is not limited to runway 2/20 either, as the field may have an
intersecting runway it could be confused with, such as runways 1/19 an
10/28.


Good point.

Two things, actually, the runway and the airport.

Yes, but missing the airport does not imply a transmission error. The
airport simply may not have been transmitted. Poor form, but not a data
error.

Hi Jose. I like your checksum argument. It's two digits for me from now
on, and we should urge everyone to adopt this convention.
