Sorry, I was addressing collision risk assessment, which involves an understanding of Hazard logs, Risk registers and Risk clasifications (Frequency and Severity) etc.
I am sure that you appreciate it is not just a case of understanding the functioning of TCAS but what protection it provides when the risk of collision is realised (Loss of safe seperation with another aircraft in class G airspace). At that point TCAS is the only "recovery control" that can prevent a collision/near miss from occurring. I am please to note, from the lastest MAA "bow tie" diagram of Nov 2014 (After the event of 2012), that this has now been recognised by the MAA.
