TCAS vs Alt Adjust
I did some research over the forum and couldn't find out anything related to this, so...
Can anyone enlighten me on a issue about the TCAS and the altimeter setting? I've been flying the bus for some time and never heard of this before.
During cruise flight, while performing the approach briefing, I momentarily pushed the altimeter setting knob to adjust the QNH at destination, as I always do.
The captain told me that I should never do that again, because doing so I can cause a RA on another aircraft nearby.
I know that I can make the altimeter alert sing, but that's just annoying and won't do any warm, but I wasn't aware that I could make the TCAS shout.
Does anyone know if it's true?? I learnt that the transponder uses the standard setting to work out the TCAS and changing the QNH won't change anything on that matter.
Where I can find some reading about it??
Thanks.
