Introducing more efficient departure operations can help to increase throughput at capacity-constrained airports. SESAR is looking at ways to define a reduction in wake separations for a following aircraft between consecutive departures using dynamic real-time data. 

The solution sees the dynamic suspension of wake separation minima, based on the predicted differentiation between the leader and follower departure trajectories. 

The concept may be applied to departure pairs where the following scenario is predicted:
- Leader: Aircraft with a late airborne position and shallow climb profile (most commonly Medium, Heavy and Super Heavy types);
- Follower: Aircraft with an early airborne position and steep climb profile (most commonly Medium, Small and Light types. 

Expected benefits are expected in terms of runway throughput capacity.
