Suggested Literature for A.S.E.S. Rating

Set yourself up for success.

By familiarizing yourself with the FAA-H-8083-23 Seaplane, Skiplane, and Float/Ski Equipped Helicopter Operations Handbook, you will be prepared for your first day of Airplane Single Engine Sea training. We recommend reading and familiarizing yourself with Chapters 1-6 and 8 , as well as memorizing the Vspeeds for our Cessna 172M.

CIGARS and FCARS are two flowchecks that are important to familiarize yourself with before starting your A.S.E.S. training. Being familiar with these two acronyms and the Vspeeds will save you time and money and allow you to focus on the techniques and skills specific to flying floatplanes.
