The TBS Transitional Step proposes a change in the current ATM procedures that will enable ATC controllers to apply a 0.5NM fixed reduction of the ICAO wake turbulence distance-based radar separation minima between wake turbulence separated aircraft pairs in specified headwind conditions and/or delivering Spacing Minimum at a distance from threshold defined as a function of wind. Compression beyond the delivery point will result in reduction of spacing at threshold that allows time spacing to be maintained even in strong headwind. The level of operational applicability and benefits will depend on local wind conditions and runway orientation.
