Unfortunately that is and has been shown inadequate for aviation use. Both fluids are the same color. Jet fuel and avgas are different colors, are dispensed with different sized nozzles. Even auto gas and diesel fuels have different nozzle sizes to prevent misfueling for road vehicles. The FAA has already taken numerous steps to avoid misfueling. In the end misfueling is easily prevented by pilots physically monitoring the fueling process. Knowing whether the proper fluid has been placed in the prist dispenser of a fuel truck is not! NTSB needs to call for getting the EPA out of aviation regulation, that is FAA responsibility. There have already been lawsuits filed on the two air ambulance aircraft that had airborne engine shutdowns due to this. Just imagine the lawsuits involved if an aircraft crashes and someone gets killed. Since my behind is flying in the cockpit of business jets, I can garantee this comment and the first one I submitted is not a “knee jerk right wing reaction”!!!
