Get back to the point everyone, the instructor shortage.
When the JAA modular training was proposed just prior to 2000 the aviation press predicted this would result in an instructor shortage as the need to build 700 hours to hold a CPL was removed; this is exactly what has happened now. The BCPLs holding self improvers were a major source of instructors to the industry.
SAS, far more people in the eighties were obtaining PPLs than they are now, therefore these "inexperienced" AFIs/QFIs were by and large making a reasonable job of PPL instructing.
To make PPL instructing a viable career option you will need to start paying PPL instructors the same as Commercial instuctors, so the price of a PPL will start becoming well over 10,000, so please don't tell me that this is going to help the industry or encourage popular flying.
Oddone,
At Denham you have technically advanced aircraft, your catchment area is London, where disposable incomes are high, there are reasons why TAA are based at Denham and not in Plymouth. That is a marketing idea that will work in London not at Plymouth or many other parts of the country.
It is simple eveyone, the biggest contributor to the instructor shortage has been the introduction of the JAA modular system.
