In the Fenix A320 how do you reduce Tcas Range??, I am getting a message asking me to do this

Use the dial to the right of the clear button. The term 'range' doesn't mean distance, it means 'the range of targets' it will monitor, such as 'only those above you' or 'only those below you' etc. So what it is referring to when asking you to set the 'range', is to put it on the most suitable mode for a climb, or a descent or level flight etc, so it will only consider threats which you are likely to come into conflict with. Setting the range of targets it will monitor may also refer to putting it on standby so you don't get warnings which are of no consequence to you at the time, for example, when taxying about on the airfield, where if you had it on 'all' it would probably be going mental; it is usually why flights on stuff such as flight radar 24 which you may have tracked will probably disappear when they have landed, which can also be a problem for flight sim add-ons which use real world transponder data to generate A.I aeroplanes which then disappear instead of taxying it on your sim's airfield. So be aware that because this is so, it is possible to put your transponder data transmission on standby as a result of some of the possible selections, which would mean ATC would lose you off their scopes as well as the TCAS mode not working. This would probably be an issue for things like VATSIM too I should imagine.

I always thought it transponder squawk code with ident button underneath. Are you sure about range?

Correct, I realised what I originally typed looked confusing because I was writing something about the transponder code as well and the post activated before I'd sorted that out properly when I was loading the image into imgur lol, That's what you get for tabbing around too may windows I guess, so I tweaked my reply. See correct post. The range is a misleading term, it actually refers to above/below/all/immediate threats etc, and is basically automatic, with it dropping stuff which doesn't matter in the background as well unless it considers it a threat. How it does that and the distance it considers is different on various airbus models too, just to make things even more fun. ✈️ As far as international standards go, TCAS is supposed to be reliable out to about 14 miles or so, but more modern systems can read stuff out to about 100 miles.

No worries 🙂

From FCOM:

 

I’m pretty sure you are supposed to reduce the range on the ND knob. That’s from what I know!

As far as I'm aware, reducing the range on the ND will reduce the range it will be displaying to you, but not changing overall range, or elevation, of targets it will be considering for collision avoidance messages, since it basically a passive system which works off the transponder as opposed to working like a radar scanner or some such, although I could be wrong about that. Guess I might have to dig my manual out...

Well, not much help from the real A320 CEO manual it would seem, here is all I can find from that one, where it basically says the same as what I had suggested, i.e. using the elevation selector to filter stuff out:

Exactly. I got a TCAS warning the other day.  Range was set to 80 mi. Saw the traffic on the ND painted right over top of me with that message.  I turned it back to 10 miles, which cleared the message and showed the target at 2 o'clock and +100' about 2 miles away.  I looked to the right, and there it was flying right along with me.

Yep that’s how I know it, I think some responses here over complicated it.

TCAS detects 80 nm ahead and 30 nm wide with different symbols and state, range can be set with ND... See video's below maybe helpful for some 😉
