Every now and again I'll get an opportunity to ride along right seat in a king air and work the radios and get a chance to fly a deadhead leg. The guy I fly with is a current MEI so I log the flight dual received and no PIC, even though I'm MEL rated on my commercial cert. So far I have about 13 hours of king air time. If I'm getting ready to send out resumes and prep for interviews, should I be concerned with technical questions over the king air if I continue to build dual received? The majority of my MEL time is in a seminole.
