EASY Question #41:

What ATC traffic separation minima is normally applied to heavy aircraft? Which separation minima apply to heavy-category aircraft? What spacing does ATC usually assign to heavy airplanes?

Answer:

Heavy aircraft are typically separated by a minimum of 5 nautical miles when under radar control, but additional wake turbulence separation can be applied. In non‑radar conditions, time‑based separation intervals are used. Also, for takeoff and landing, the necessary interval is 3 minutes.
