NSA’s assessment of capacity performance

Traffic is still significantly above the planned traffic in the performance plan.

En route capacity performance was achieved.

Monitoring process for capacity performance

NM statistics used for monitoring.

Capacity planning

Performance was appropriate, all delays casued due to weather.

Application of Corrective Measures for Capacity (if applicable)

The ANSP has implemented additional shift and increased training of ATCOs to handle increased traffic demand.
