I'm having a little trouble understanding which one I should learn. I want to eventually get a job as a pro pilot like most pilots, but I have a very big question. What is the proper way to perform the checklist. I understand the callout checklist, but is that 24/7. Who uses the flow process because I kno comair teaches it. I'm debating whether I should change instructors for my multi engine training to learn the flow, but I don't kno...is it the way to go or should I just stick to reading the checklist??
