To identify the differential contributions of these factors, three baseline conditions without HUD localizer guidance symbology and two conditions with HUD localizer guidance symbology were used. Currently, only about 30% of the CAT I runways in the NAS are equipped with CLL. Therefore, the human factors considerations in using HUD localizer guidance in lieu of CLL in low visibility conditions were of principal interest. The results of this study have the potential to inform operational credit changes that would allow more reduced visibility takeoffs and increase the number of viable airports available for takeoff under low visibility conditions. The research was conducted on a Boeing 737- 800NG Level D simulator at the FAA Flight Technologies and Procedures Division facility in Oklahoma City, Oklahoma.119
