TCAS for low level traffic avoidance????
Hello everyone. I'm a tower controller from Ireland and I've a wee question for you.
Recently I've noticed that when i pass traffic info to VFR Helis transiting through the zone, some of them (1 in particular) replie "yeah, we have him on TCAS".
Now, I'm spending nearly all my time on the ground and even though I'm familiar with TCAS, TAs and RAs, and even though it's reliant on mode C, I'm thinking it's not exactly a surveilance radar.
So can someone tell me, is TCAS useful in a Low level VFR situation?
More to the point, Is using TCAS considered an acceptable substitute (by anyone) for having traffic in sight? (I say No)
And finally, does anyone have any further to add...
