Final answer:
In aviation, a small aircraft landing behind a large aircraft conducting a low approach must maintain a separation of six miles for safety from wake turbulence.
Step-by-step explanation:
In aviation, specifically in air traffic control, the separation between landing aircraft is critical for safety and efficiency. As per standard aviation protocols, when a small aircraft is landing behind a large aircraft conducting a low approach to the same runway, they must be separated by a minimum of six miles to ensure safety from wake turbulence. The wake turbulence generated by large aircraft can pose significant risks to smaller aircraft following too closely, potentially leading to loss of control.
