Ground instructor qualifications for ATPL
One ground school instructor at an FTO I attended in 2004 was one of their own ex-students who had only completed the ATPL groundschool course a year or so earlier and did not even have a CPL.
Actually, the person concerned was very good, really knew the stuff and was good at teaching it. But I found myself wondering about the reliability of the CAA's vetting process if someone with no professional experience of any sort could get the job and keep it on the basis of just one lecture given with a CAA henchman present.
