Video Tip: How to perform a Cessna 172 exterior preflight
The airplane preflight inspection is performed before each flight to ensure that all the required paperwork is on board, that the airplane systems are working properly and that the correct amount of fuel and oil are in the tanks. It’s your chance to really look the airplane over inside and out to assure yourself that it’s ready to fly, because once you’re airborne, you just can’t pull over in case something goes wrong.
