Scenario: A private instrument rated pilot is working on their commercial. They need to get the 10 hours of complex time and come to an FBO to fly those 10 hours. They fly with a CFI. The weather becomes IFR. Can that CFI give dual in IMC in the complex plane if he is giving instruction on the complex and not giving instrument instruction? I have had mixed answers with this question and wonder if the instructor needs to be a CFII. I read 61.193 and 61.195 paragraph c and am asking for some clarification. Thank you.
