For night operations, what size is preferred for additional touchdown points for cargo aircraft?

The preferred size for additional touchdown points for cargo aircraft during night operations is 10 meters by 10 meters. This size is optimal because it provides a sufficient area for the aircraft to make safe landings while minimizing the risk of accidents or damage to the aircraft. A 10m x 10m touchdown point adequately accommodates various cargo aircraft dimensions and allows for potential lateral movement needed during landing, particularly in low-visibility conditions that are common at night.

Choosing this size balances operational efficiency and safety, ensuring that the aircraft can land appropriately without endangering the crew, cargo, or surrounding personnel. In contrast, the other size options may either be too small, leading to increased risk during landing, or larger than necessary, which might complicate the logistics and planning of night operations.
