How to Preflight Your Airplane:
In this topic, we’ll cover how to do a proper preflight on a Piper Cherokee. You’ll find preflighting any airplane is almost the same, with just a few differences between each one depending on the specific systems installed on that particular plane.
Luckily, each airplane has a manual with it you can find inside the airplane called the POH or Pilot’s Operating Handbook. Inside the POH you’ll find a section of how specifically to inspect your particular airplane and in what order.
An example of the preflight section in a POH is below.
About the Fuel
Your airplane most likely only runs on one specific type of fuel. You should see what type listed in the POH and/or on a placard (sticker) next to the fuel cap.
WHAT YOU NEED TO KNOW ABOUT FUEL TYPES:
Jet A = Clear
100LL = Blue
100 = Green
80 = Red
Careful! Water is clear too!
