ability to escape through dense smoke as "highly speculative". As a result of analysis of the crash, the FAA instituted new flammability standards for seat cushions which required the use of fire-blocking layers, resulting in seats which performed better than those in the test. It also implemented a standard requiring floor proximity lighting to be mechanically fastened, due to the apparent detachment of two types of adhesive-fastened emergency lights during the impact. Federal aviation regulations for flight data recorder sampling rates for pitch, roll and acceleration were found to be insufficient. NASA concluded that the impact piloting task was of an unusually high workload, which might have been reduced through the use of a heads-up display, the automation of more tasks, and a higher-resolution monitor. It also recommended the use of a microwave landing system to improve tracking accuracy over the standard instrument landing system. In practice, the Global Positioning System-based Wide Area Augmentation System came to fulfill this role.
