Safety assessment activities to support the introduction of new safety nets

Deep Blue performed the functional hazards assessment (FHA) and preliminary system safety assessment (PSSA) associated with the introduction or improvement to ground-based safety nets.

We conducted these assessments in support of different air navigation service providers.


For example, one study concerned the adaptation of the short-term conflict alert (STCA) concept to the specific needs of a Belgian military service provider (ATCC Semmerzake).


Another study aimed at improving the performances of the minimum safe altitude warning system in the Swiss service provider Skyguide.
