The strongest wake turbulence vortices are generated by which type of aircraft?

Explanation:
Wake turbulence strength comes from the energy in the wingtip vortices created by lift. The heavier the aircraft, the more energy is put into those vortices, and the slower the aircraft flies, the less quickly those vortices dissipate, making them stronger and longer-lasting. A clean configuration (flaps up) tends to preserve that strong, compact vortex rather than dispersing it more quickly with extended lift devices. So the combination that yields the strongest wake is a heavy aircraft flying slowly in a clean configuration.
