The pressure to increase airport capacity and throughput requires extreme accuracy and surveillance reliability in terms of approach to parallel runways to ensure that aircraft do not enter the high-risk zones between the arrival and departure corridors.

​

The high accuracy and high update rates (1 second or even less) of the multilateration system guarantee safety at even the busiest airports with parallel runways.

​

Parallel Runway Monitoring is therefore an important application of the multilateration system with its verified and proven ability to provide greater safety while significantly increasing landing capacity.
