I'd also like to know what new policy is referenced. I sit on the Gatwick Local Airspace Infringement Team (pretty much all large airports have a problem and hence a local team) and haven't heard from the CAA representatives that policy has changed / is changing. I guess Fuji is saying he has heard that more and stricter consequences are going to be enforced.
Infringements should be and always have been taken seriously and our aim is to try and prevent them because we have to fight hard enough to keep some airspace to fly in as it is; without abusing what we don't have.
Education encouraging "better" behaviour is the key to that. The aim of the team is to improve the situation and simply doling out punishment is not going to either endear us or promote participation in better infringement avoidance.
