An aircraft fueler has many job duties, all of which are completed outdoors in a wide variety of weather conditions. Some companies refer to this position as a fuel handler instead of an aircraft fueler, but the job duties are the same. As an aircraft fueler, you work diligently to refuel airliners and jets with either aviation gasoline or jet fuel, depending on the model. You climb ladders or step stools to access the fuel port on the planes you are refueling, attach a large hose to the aircraft, and pump the fuel into the plane from trucks on the ground. This job can be dangerous, and some of the responsibilities associated with it are considered hazardous.
