CONCEPT
We all know that not everything in existence on this earth is
perceivable with our senses…( radio waves, x-rays, whale song, etc. ) .
Yet it exists.
We need a medium to make these phenomena perceivable to us.
In my case, it was an air traffic control radar station that made the
lines I drew in the air with my Robin 300 visible. Like the lines drawn
by a pencil when it touches paper, the secondary traces of radar are
captured when the transponder is on.
The printout of these radar blips ( RDR RDQC ) makes it all visible.
An individual transponder code is necessary so that only the traces of
a single plane are registered ( X-3704)
We are still left with one problem….that of perception.
Actually, to be precise, there are two problems.
Due to the size of these drawings, a person is not able to view it
fully, just as one is not capable of discerning the melody in an
extremely slow piece of music.
Our vantage point only allows us to see an airplane flying above us.
It is radar plotting that makes it all tangible for humans.
