The HUD allows each pilot to see the big picture and critical flight information at the same time. By allowing lower takeoff minimums, the head-up display helps minimize costly ground delays during periods of low visibility. The HUD enhances safety, and it provides a platform for future advancements in flight guidance and navigation displays. 3-4 right, maintain 2000 till established.
