What minimum separation does ATC provide for a small aircraft landing behind a heavy jet due to wake turbulence?

When a small aircraft is landing behind a heavy jet, air traffic control (ATC) must ensure proper wake turbulence separation to avoid hazardous conditions. Heavy jets generate significant wake turbulence due to their size and weight, which can particularly affect smaller aircraft.

The minimum separation that ATC provides in this scenario is typically 6 miles. This distance helps ensure that the smaller aircraft is clear of the turbulent wake that can descend and drift with the wind. Wake turbulence can pose a serious risk, making this precaution essential for safety during takeoff and landing.

The other options do not meet the established safety standards set by aviation authorities for wake turbulence separation behind a heavy jet. Therefore, the correct answer reflects the safety protocols needed to ensure that small aircraft can safely operate in the vicinity of larger jets.
