How long
It is not for the RT Examiner to decide the pace of the test. If the candidate wishes to use real time then they may without explanation. I explain this to all candidates during the pre-brief so they do not feel under pressure to move on without being ready.
Recording the test is an option of the Examiner. It is not mandatory and I rarely do it. When i have recorded all or part of a test it is to be a helpful tool during a post-flight brief rather than evidence of failure. If a candidate arrives with shortcomings and leaves without them i am satisfied. All this is in accordance withe the CAA brief to Examiners.
Any incident that appears to need assistance requires a 'PAN' call.
