MP, you should have told the CAA that you were not P1 and quoted the PPrune posts last year were quite a lot of the self appointed experts on here were adamant that if you were engaged on a check ride as an instructor with a qualified pilot you could not be P1, funny how none of them have picked up on this!
Also not mentioned is that you could have brought down a public transport flight with disasterous consequences, I wonder how the 'experts' would have viewed your incursion then?
Your conviction will shew on a CRC check, so I would be very suprised if any major airline would employ you and I speak as a retired ex management pilot. If you were involved in an incident with an airline and your prosecution came to light it would not look very good for that company would it?
The commader is decided before flight but the role of commander needs to be understood at a much earlier stage as this incident proves.
