The color, lighting, and markings of Aircraft Rescue and Firefighting (ARFF) vehicles are critical to safe airport operation. The FAA Advisory Circular AC 150/5210-5D states: “Yellowish-green is the vehicle color standard.” However, recently the age of this AC has led to questions regarding whether it needs to be re-evaluated in accordance with recent advances in color schemes, paint materials, retroreflective materials, and lighting packages. The resulting FAA-sponsored project is being undertaken cooperatively by Ohio State University, Iowa State University, and Texas A&M University. The attached PDF provides more context and describes initial progress. The group would also like extensive feedback from practitioners who have experience in this area. To achieve this, a survey has been developed to record the broadest possible range of specific experiences with this color while also establishing user perceptions regarding how the AC might be modernized.
