The Backseat Pilot Reference Card;

We're pilots, we get it, there's a mountain of knowledge to keep straight in order to ensure the safest flight possible. That's why we tirelessly scoured the FAR/AIM and picked the brains of flight instructors and flight students in order to establish the most critical, difficult to retain, and useful information for any pilot to have on hand at any time. We then compiled this information into a simple, organized, and attractive reference card which would not be oversized or obtrusive in the cockpit, or on the kneeboard, and finally had it digitally printed on the most durable and suitable material we could find. We have never seen anything as useful, organized, and thorough on another reference card or kneeboard.
