National Risk Register

The government has published its 2023 edition of the National Risk Register. 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...

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. It looks like some unexpected data in the plan caused the primary and backup software to fail. 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.

The IET has announced the Young Women Engineer of the Year Awards 2023, https://youngwomenengineer.theiet.org

Time Set for National Mobile Phone Emergency Alert Test (Apr 23)

On Sunday 23rd April 2023 at 3pm UK time there will be a test of the national mobile phone emergency alert system which should send a message to about 90% of phones in the UK. In the future true alerts could be more localised to a specific area. This could be a very useful system. Any info about how it is being implemented, and presumably assured, would be appreciated. mike.parsons@scsc.uk
