Firstly, you should check to see if your training has been properly documented i.e. each flight has been recorded together with comments regarding your performance. Has the training followed the published syllabus, and if not why not? Which exercises have you had to repeat, how many times, and what are the reasons given. Training records will either identify your weak areas, or alternatively, will show up the organisation training you as not doing the job properly. Have you been debriefed after each flight, and have you ever been asked to sign the debrief to acknowledge that you have been told about your performance and any shortcomings?
