During my flight training I often heard the term "a company traffic" in radio calls from the ATC like:
N123AB a company traffic is joining downwind runway 24
What does "a company traffic" mean? Why not just mentioning the type of the aircraft like:
N123AB traffic a Piper Archer is joining downwind runway 24
Note: I'm flying in Europe (Switzerland), so maybe it's only used by ATC in my area.
