What are the markings used for Night Operations in helicopter landing zones?

For night operations in helicopter landing zones, the correct markings include the inverted Y and NATO T. These specific symbols are essential for guiding pilots during low-visibility conditions, allowing them to identify the landing zone accurately. The inverted Y marking provides a clear indicator of the centerline of the zone, which aids in alignment for landing. Meanwhile, the NATO T serves as an additional reference for direction and orientation.

These markings are recognized internationally, ensuring consistency and safety in helicopter operations, especially while conducting missions that require precision and clarity in challenging visual environments. Proper use of these symbols can significantly reduce risks associated with night landings, thereby enhancing operational effectiveness and safety for both the aircrews and ground personnel.
