Hands up all those who have flown FJs with TCAS. How many of you found you get over-saturated with TCAS alerts in normal training and wish you could turn it off?
In my experience it is a great SA tool when transiting around congested airspace, but it becomes a massive pain in the butt whenever you are doing any dynamic manoeuvring. Constant TCAS alerts from within your formation tend to cause you to become deaf to the system and ignore it at times. "Oh it's just no3 etc...)
There's still a way to go before it becomes truly useful in FJ ops in my opinion.
