What Does HAC Stand For?
HAC stands for Heading Alignment Cone
HAC, or Heading Alignment Cone, is a navigational tool used in aviation and maritime industries to visually represent the optimal alignment of a vehicle's heading relative to a predetermined flight path or course. The cone-shaped projection assists pilots and navigators in maintaining accurate directional guidance, enhancing safety and efficiency during travel. By indicating acceptable deviation limits, the HAC aids in situational awareness and decision-making processes when adjusting headings.
