For CH-46 with RB 85 ft, what are the day and night HLZ values?

Explanation:
HLZ values show how much landing zone length is required for a given helicopter, based on rotor size and lighting conditions. With an 85 ft rotor diameter (RB 85 ft), the daylight requirement is 185 ft because daylight allows pilots to gauge clearance precisely and land with less ebb and flow margin. At night, visibility is reduced, so extra clearance is added to the landing zone to maintain safety during approach, hover, and touchdown, resulting in 235 ft. So for this CH-46 configuration, the day HLZ is 185 ft and the night HLZ is 235 ft.
