When utilizing the NATO T, how many lights are used to mark the touchdown point?

In utilizing the NATO T for marking a touchdown point, five lights are used as part of the established protocol. The NATO T consists of a specific arrangement designed to guide aircraft accurately during landing operations, especially in conditions where visibility may be limited. The use of five lights enhances the visibility of the touchdown point, providing clear guidance to pilots. This configuration allows for a distinct and recognizable formation that is crucial for safe and effective air operations, ensuring that the landing area is unmistakably marked. The effectiveness and safety in landing operations are paramount, and the five-light system plays an integral role in achieving that standard.
