I wasn't aware CHC were teaching that condition. I don't demonstrate or train AP off flying with students (either VMC or IMC) unless they can first complete all the other training sequences with both AP on. If we complete all the syllabus training within the allocated time to an acceptable standard then we will attempt AP off flying. I don't recall ever seeing a student get from IMC to VMC with both AP off. After double AP failure in IMC the students are usually totally out of control within about 10 seconds.
