How long must Category E through I aircraft wait to land behind a departing Category B, C, or D aircraft?

Category E through I aircraft must wait 2 minutes to land behind a departing Category B, C, or D aircraft to ensure safe separation and to prevent wake turbulence that could adversely affect the stability of the following aircraft. The 2-minute interval accounts for the time required for the wake turbulence to dissipate and for the aircraft to gain sufficient altitude and distance from the runway, reducing the risk of encountering hazardous wake vortices. This established time frame is based on aviation safety protocols and helps maintain operational efficiency at airports while prioritizing safety for all aircraft in the airspace.
