Having read back through the thread it appears that only two posts are critical of the pilots. It is clear from his terminology that one has never been within 1000 miles of Oxford. The other, it would appear, has registered for the express purpose of making his first Pprune post on this subject, a post which is very defensive of the (not yet literally) fatally flawed system in use at Oxford - Doesn't that, combined with the significant lack of detail in his profile, tell us all something?
The fact is that cost-cutting has resulted in an overall drop in the experience level of Oxford instructors. This is, in itself, not a problem provided that adequate training and support is given. However, the amount of initial orientation training offered to new instructors has also been cut. Similar cost-cutting has decreased the effectiveness of ATC by handing it to an outside contractor. As if this were not sufficient recipe for disaster, the pressure is on to force more and more aircraft into already overloaded airspace.
The fault clearly lies with the money-grabbing senior management, not with the instructors who did not get the support they deserved to compensate for their inexperience.
