All daytime single-light aircraft use which TDP size?

The correct answer indicates that all daytime single-light aircraft use TDP Size 5. TDP stands for Touchdown Point, which is critical for ensuring that the helicopter has a designated area to safely land and take off. TDP Size 5 is specifically sized to accommodate the unique needs of single-light aircraft during daylight, considering their reduced size and weight compared to larger helicopters.

This TDP size ensures that there is adequate space for maneuvering, reducing the risk of obstacles or terrain issues affecting the helicopter's landing. Additionally, using this size helps standardize landing procedures, contributing to overall operational safety and efficiency. Choosing the appropriate TDP size is essential for mission success, allowing for recurring operations in various environments without compromising safety.
