Which MTOW threshold defines the HEAVY Wake Turbulence Category?

Explanation:
Wake turbulence categories are defined by maximum takeoff weight to reflect how strongly an aircraft can generate vortices. Heavily weighted aircraft produce stronger wake vortices, so they require larger separation from following aircraft. The dividing line places Medium between the lowest category (Light) and the heaviest category, with Heavy starting at 136,000 kg and above. So, any aircraft with MTOW of 136,000 kg or more falls into the HEAVY category, because its wake is powerful enough to demand greater spacing for safety. We typically say lighter aircraft are up to 7,000 kg (Light) and then 7,000 kg up to 136,000 kg (Medium), with Heavy beyond 136,000 kg. Therefore the correct threshold for defining Heavy is 136,000 kg or more.
