COVID-19 compels aviation industry to speed up the modernisation of the ATM system and prioritise business continuity

Frequentis emphasises benefit of SESAR virtual centre concept during pandemic

Today’s operational ATC concept does not allow other sectors to immediately take-over operations, if area control centres (ACCs) are taken out of service. This calls for a modernisation of the ATM system, building on virtualised ATC centres for ACCs and tower, with built-in business continuity, beyond national or regional borders.
