AI Safety is Big News (Oct 23)

There have been many significant announcements about AI safety, the biggest of which is from the US today. This initiative has potentially huge consequences for those developing and deploying AI worldwide. It is also the week of the UK government AI Safety Summit at Bletchley Park which could have some useful outputs. Note that at SSS'24 in February we have a special "Can we make safe AI" session with talks and panel of experts, All our 1-day seminars are AI-themed next year too, starting with the first one in April.

NATS Outage (Sep 23)

The recent air traffic control disruption at NATS due to a flight plan has made many headlines and details of the causes are now being made public.

Both the upcoming SCSC Working Group meetings on Data Safety and Complex Systems will discuss the incident. However we shouldn't forget that the whole arrangement of aircraft and crews, rosters and allowable hours contributed to the problems - highlighting an astonishingly fragile complex system (in fact a service). From a robustness perspective, there should have been contingencies at every level so that the knock-on effects were reduced. We await the formal reports into the matter but there are clear lessons already: expect the unexpected and have backups which are diverse in nature.

It makes interesting reading - there are quite a few systems-related risks, for instance: Rail Accident, Aviation Collision, Malicious Drone Incident and Deliberate disruption of UK space systems and space-based services. It is probably worth considering if your risk register should include some of these wider risks...
