OK chaps this is very interesting - So far no one has answered the questions posed BUT one reply said that PPLs dont get enough flying to stay current in his opinion and that it will get worse, another said that the syllabus isn't good enough to teach navigation properly but it is not their fault. Another said that its really demanding flying in the SE of England and yet another said that flying within 1/4mile of a CAS boundary is fine.
One reply suggested that if pilots monitored APP frequencies then a blind call might stop an infringememts.
Recently an approach controller did just that - the infringing pilot switched off his altitude encoding TXPDR and continued through the zone. Not only did he cause a lot of avoiding action, he also took away the other pilots last line of defence for stopping collisions - TCAS.
It is actions like that that turn controllers in to cycnical people
But seriously for the education of people who read this forum - just what is the real number of infringements, have you infringed, were you traced and what happened - or is it too traumatic?
