If I gave the impression that I meant to imply otherwise, I apologize
to N2EY. There are numerous Q-signals that were originally for
aeronautical use, back when CW was used for communications with
airplanes. I was just pointing out that they aren't used anymore.
Comms between aircraft and from air-to-ground are in AM mode. No need
for q-signals there, and as I say, the ATIS tells the flight crew
which runway is in use anyway.
