Under the new system why a debrief, you don't get that at commercial level. You sit an exam, result pass or fail. If fail is there any guidance on where a candidate went wrong.
You miss the point entirely. There are significant differences between theoretical knowledge exams at private and professional level:
- Theoretical knowledge actually necessary for every day operations will soon become familiar to the professional pilot through company SOPs and ‘on the job training’ (OJT). However, there is no OJT for private pilots, so they may well continue their flying with blissful ignorance of why they failed a particular question, even though they passed the exam. Which could be fairly critical.
- Private pilot exams are invigilated by an Examiner who is available to debrief the applicant after the exam has been completed. Whereas professional exams are conducted en masse with oversight provided by an invigilator whose primary responsibility is to prevent cheating.
- Unlike an automated system, an Examiner can assess whether a failed question was due to a genuine gap in knowledge, or simply the result of a mistake - e.g. a question concerned fuel loading in US gallons and the applicant used the SG value for Imperial gallons.
