I will not try to convince you that TCAS is suitable for ACT sorties. That’s because I don’t believe it is. But I don’t make the rules.
The warnings are annoying. However, as I said, after the Moray Firth crash it is hard to argue that it should ever be turned off.
Every argument you are about to say has already been considered. We are all aware of its limitations but it also has its benefits at times. In IFR airspace it has obvious uses but it has also proved it’s worth at low level when big sky theory has let us down.
I’m sure Distant Voice would remind us that, despite it’s drawbacks, it probably would have prevented the Moray Firth collision even in its present form.
