Re: I'll tell you one thing...
I think the problem is that CFIT sensors can be fooled, throw false alarms, or be overridden
Such alarms are regularly ignored.
When I was doing my retractable undercarriage training, the aircraft I was flying had an alarm that sounded below a certain height if the wheels were still up and the engine revs dropped below a certain level.
During the week, we fly a lower circuit than at weekends. So as soon as I reduced power, the alarm would sound. Every single circuit. And so the alarm gets ignored.
 Thruxton is situated within the Boscombe Down / Middle Wallop CMATZ, so on weekdays, when Boscombe is active, we have to keep low to make sure we don't interfere with anything they might be flying.
