Generally there seems to be 2 sides to this discussion.
1) What are Brymon doing laying down entry requirements such as these?
2) They are the employer so they can demand what the hell they want.
Both sides are quite understandable. Scroggs has said:
The bottom line is that in BA's opinion (and experience), the recent graduate from an integrated course is more likely to pass their demanding training than a low-hour modular graduate, hence the insistence on the (still low) hours for modular candidates.
This is why 1) has arisen.
Now this opinion has presumably been formed from historical analysis, when people would have been on the old 'self-improver' route.
Re 2) - If I was the CP of a company with this knowledge then of course I would want to minimise my risk (read maximise long term growth/profit) for the company. The lack of need to process 100's of additional CV's therefore would be quite justified and the ad would be appropriate.
However the new JAA modular route is addressing the concerns of the previous system. Namely, in some cases people could scrape through the course taking for ever at a non-approved FTO, and some of them may not have been taught to the same standard/or be as current as a 509'er would be.
The problem is that industry has not seen nearly enough of these JAA Modular folk to form an opinion any different from their current one.
If this does happen then we should not see adverts like this in a couple of years time plus. However, if we still do, then it can be concluded that the industry is still short of respect for the qualification, and in which case there is an argument that it should not be offered at all, as it is of little use.
Speaking from within my current position, I personally feel that somebody who has 250 hours from the modular route would be a
better choice than a 509'er.
I remember when at University having an informal chat with the admissions tutor for our course. It went along the line of number of (A level) points needed for entry. If a public school candidate had the same number of points as the 6th form college student (all other things being equal) the the college person won the place. This was because in the University's experience the person who had worked off their own back was less likely to drop out that the person who was continually spoon fed/kicked up their @rse.
I suspect as somebody else mentioned the demography of what type/age of people took which course had a great deal to do with the situation rather than the course content itself.
Not that any of that is going to help you folk with JAA Modular ATPL's I know, but it is just a little something to chew on.
No apparently 750 hours blasting a hole in the US skies in a C152 will get you an application form, and make you more trainable, because of course you will then be far less likely to have learned bad habits than when you had 250 hours

.
However folks there is no point in bitching, as it will not change the situation. I bet the Oxford marketeers et al must be in heaven reading this!
