• Abstract:
  The International Civil Aviation Organization (ICAO) has suggested using a continuously illuminated bar of red in-pavement lights at Land and Hold Short Operations (LAHSO) locations; however, the United States currently uses a pulsing bar of white in-pavement lights. Since a bar of red lights usually means a go-no-further signal to a subject pilot, the ICAO suggested system would need to be automated to indicate between LAHSO and non-LAHSO operations. The purpose of this effort was to determine the critical flight situations, from the subject pilot's viewpoint, under which the LAHSO red light bar must be on and off during high-capacity operations at an airport. The objectives of the evaluation were to (1) determine the appropriate clearance distance, 1 nautical mile (nm) versus 2 nm, under which the LAHSO red light bar should be turned on and off; (2) determine if there were any differences in the landing distance when clearance to land was given at 1 or 2 nm; (3) determine the subject pilot’s reaction under malfunction(s) of the LAHSO red light bar; and (4) determine if subject pilots considered the LAHSO red light bar to be an effective visual presentation for communicating a go-no-further boundary. The evaluation was conducted at the Federal Aviation Administration Mike Monroney Aeronautical Center using the Boeing 737-800 simulator. Twenty-five subject pilots that were rated in a B-737-800 aircraft and familiar with the simulator participated in the study. Each subject pilot was presented with ten different scenarios alternating between LAHSO and non-LAHSO clearances, with eight reflecting normal operations and two reflecting malfunctions deviant from normal operations. Malfunction scenarios were added to test any potential mishaps that may be encountered with an automated system. All test scenarios were conducted in visual flight rule conditions during dusk and night. The entire setup and testing of the system took approximately a year and a half to complete. The results indicated that 44% of the subject pilots expressed concern about not receiving clearance during 1-nm clearance scenarios with a possible conflicting state of the LAHSO red light bar. All subject pilots were comfortable with the 2-nm clearance scenarios regardless of the state of the LAHSO red light bar. There were no significant differences between 1- versus 2-nm clearance and landing distances. Regarding the malfunction scenarios, all subject pilots viewed the illumination of the automated LAHSO red light bar and considered the change of state as a change of clearance from non-LAHSO to LAHSO. When the LAHSO red light bar was off, all subject pilots maintained that they were still under a LAHSO clearance and were able to come to a complete stop prior to the hold short line. All subject pilots considered the LAHSO red light bar to be effective, with 72% rating it as very effective.
