What is the minimum separation for a Small aircraft following behind a Heavy aircraft?

The minimum separation for a small aircraft following behind a heavy aircraft is established at 5 miles. This requirement is essential due to the significant wake turbulence generated by heavy aircraft, especially during takeoffs and landings. Small aircraft are particularly susceptible to this turbulence, which can cause loss of control if they fly too closely behind a larger aircraft. The 5-mile buffer provides a safety margin that allows the smaller aircraft to avoid potential turbulence effects, ensuring safer operations in the vicinity of larger aircraft. This guidance is important in maintaining safe distances in the airspace and is a standard practice for aviation safety.
