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


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.

Not a data error? If the pilot doesn't identify the airport I may have to
ask him where he's going. If he does identify it and it's not the airport
I'm going to I can ignore him. The location is important data.

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

Roger,... landing on runway 2 over L
or wooould that be.. runway 2 divided by L?

For everyone else.. That would be Runway Two Left
I hate it when people call "on the downwind for two" or "two zero", and
don't specify Left or Right downwind or Left or Right Runway

If one announces "Runway Two Zero" but the "Zero" is cutoff the listener
thinks "Runway Two". Announcing "Runway "Zero Two" prevents this
possibility.


Why does announcing "Runway Two Zero" allow the last digit to be cut off
while announcing "Runway "Zero Two" prevents the last digit from being cut
off?

It doesn't. It prevents the last digit from being cut off =unawares=.
It acts as a checksum of sorts. If all runways are two digits, then any
transmission missing a digit is suspect. If some are one and some are
two, then there are some cases where an error would not be noted; this
is especially the case with runway 2-20, both of which exist on most
airports for which one exists.

I once flew to an ratehr rundown airport with a 2-20. The Unicom was
so badly garbled that I even after asking Unicom to "say again" three
or four times, I had no idea whether the guy was saying "zero two" or
"two zero."

No wind tee, wind sock to bedraggled to make out from pattern
altitude.

Based on winds in the general area, I suspected he was saying "zero
two" so I asked him "Runway 2?" and he came back with the same number
of garbled sylables as before.

Hearing no other traffic after two circuits, I finally just landed on
runway 2 and tried to teach the guy how to announce runways.

Had he said "Runway two," I would have known from the number of
syllables which runway he meant.

"Runway one plus one, or runway ten plus ten?"

You don't think it's likely that the Unicom guy would say anything
like that, do you? If he had it wouldn't have helped; same number of
syllables either way.
