You may be right about the prosecution side of things.
But what concerns me is that over the past 2 years the number of reports of incursions on the monthly report around certain large airfields has gone up.
I would doubt that is due to a worsening of pilot skills (although quite possible) but rather due to greater reporting.
Why would that be? Possibly so that NATS can go to the CAA and beg for more CAS to protect the self-loading freight.
I think a more reasoned approach would be to look at why incursions happen and redesign the airspace to improve things - being restrictive is something different.
There are a whole lot of 'pinch spots' (Luton -Stansted gap for one) where airspace design is poor and minor errors in navigation can put you in the brown stuff fairly quickly.
This questionnaire, well-meaning as it may be, isn't going to help make us feel 'loved' by NATS, but will probably be seen as a pre-emptive attack on many of us (just as the TMZ was)
