"One thing though I think needs to change is airline pilot trainers examining their own pilots. There is a potential incentive for company type rating examiners, TREs, to get their pilots through their SIM exams. I personally think that SIM exams should be conducted by aviation authority examiners, who do not know the candidates. This might help reveal issues, if they existed."
I asked in the Air India accident thread if this system applied in India or if they still used the government examiners as we used to. but it was passed over without comment.
My adviser from within the industry is disappointed with our system as it stands. He feels that the authorities really have little power to control or improve the quality of airmanship when type rating checks are done by company pilots...
