What is the separation time required in a non-radar environment if departing from a farther point than the heavy aircraft’s departure?

• A. 4 minutes
• B. 2 minutes
• C. 3 minutes
• D. 1 minute

Answer: (C)

In a non-radar environment, the separation time required for aircraft departing from a point farther away than a heavy aircraft's departure is essential for safety considerations, particularly due to the wake turbulence generated by larger aircraft. The correct separation time in this scenario is indeed three minutes. This separation interval is recommended to ensure that the leading heavy aircraft has time to generate enough distance and altitude to mitigate the wake turbulence effects on the trailing aircraft. Wake turbulence can linger in the flight path of an aircraft for a significant amount of time, and three minutes helps to provide adequate spacing, reducing the risk of a trailing aircraft encountering hazardous conditions. While a longer separation time could enhance safety further, it is essential for air traffic management to balance safety with operational efficiency, which is reflected in the established three-minute rule in non-radar environments for this specific situation.
