According to DOC 4444 (ICAO), what is the required wake turbulence radar separation minima for a MEDIUM and LIGHT aircraft using the same runway?

• A. 2 NM.
• B. 4 NM.
• C. 3 NM.
• D. 5 NM.

Answer: (D)

The correct answer reflects the requirements set out by ICAO in DOC 4444 regarding wake turbulence separation minima between different aircraft categories. In this case, when a medium aircraft is followed by a light aircraft, a separation of 5 nautical miles is mandated. This distance takes into account the wake turbulence created by the medium aircraft, which has a higher potential to disturb the airflow around the light aircraft when departing or landing on the same runway. This requirement is crucial for safety, as wake turbulence can significantly affect the performance and control of the trailing light aircraft. The 5 nautical miles ensures sufficient distance to allow the light aircraft to operate safely without being adversely affected by the wake turbulence. Understanding that this specific distance is defined by ICAO illustrates the emphasis on maintaining safe operations in various flight conditions.
