Perfecting the checklist is our passion.

We all try to be the best pilot we can be, with safety as our first concern. No doubt you've put in the requisite time, money, and effort to keep your aircraft's powerplant, airframe, and avionics in pristine condition. Maybe you religiously use a checklist, or occasionally glance at it to make sure you hit all the high points.  

Qref checklists support smooth, streamlined execution and constant situational awareness the entire time you're at the controls. Qref's staff of Master CFIs have pooled their over 40 years of active industry experience to develop a checklist system that promotes industry best practices throughout every phase of operation. Since 2008, Qref checklists have been sold worldwide.

We sell direct and through an extensive network of over 200 pilot supply shops, FBOs, avionics companies and pilot training facilities.
