Step Turn:I am having difficulty understanding how you can "push the P1 responsibility onto the other pilot" yet still retain the RIGHT to intercede in the control of the aircraft. To follow your logic let us say, for example, you intercede incorrectly and there is an accident. Do you think that the "P1" and his lawyers would be happy for him to shoulder all of the blame and for you to walk away scott free?!!!!
This is not an attack on you - its just extrapolating the arguement to show its flaws.
