National Air Traffic Control Service - the need to pursue "Absolute Zero"


The National Air Traffic Control Service (NATS) traces its history back to the early days of commercial aviation in the United Kingdom in its pioneering role utilising a rudimentary form of air traffic control based on flag signals. Modern commercial aviation however demands both the use of complex information management systems and highly skilled human labour with the NATS employing just over 2000 air traffic controllers handling 2.2 million flights annually.  To meet this challenge the organisation is “committed to delivering exemplary service performance and, through consultation with our customers, identifying and implementing new standards in service quality”.

National Air Traffic Control Service £623M Swanwick site which serves as the nerve centre for the management of UK airspace has seen its share of teething problems at its inception and software issues during the summer but the 7th December 2013 witnessed a catastrophic failure of its management systems which Eurocontrol, Europe’s air traffic control monitor, reported "Around 130,000 minutes of delay are currently expected with approximately 1,300 flights (almost 8% of the European traffic today) being severely delayed".

An investigation into the incident revealed that there was a breakdown in the IT systems with "more than a million lines of software" compromised significantly affecting the internal phone network that not only supports interaction between air traffic controllers within the same room but also with regional air traffic control authorities on the European continent. This seemingly straight forward technical issue was blamed on the "difficulty switching from night time to daytime operation" thereby making it impossible to reconfigure voice communication systems which is organised into sectors to cope with the demands of daytime UK airspace traffic.

The inability of NATS to meet its service plan objectives contributed to poor service performance levels with 20% of departures at Gatwick Airport hit by delays and 50% of flights at London City Airport faced disruption.

A cursory review of NATS 10 year business plan reveals a limited emphasis on contingency planning with quality issues shrouded by terms such as efficiency and innovation despite having a quality management system. Unfortunately there has not been a balanced strategic approach to the management of non-financial risk with effort being expounded on safety and emissions reduction to the detriment of the reliability of mission critical information management systems. This was compounded by a failure to test contingency measures or effectively mobilise contingency plans in the event of catastrophic failure.

Increasingly in our technological age firms and nation states are exposed to information risk either through limited access to information, loss of information and inaccurate information that affects not only competiveness but also safety and security. In essence sustainability is now a four legged stool consisting of the economic, ecological, social and information.  Sustainable organisations must combine the goals of "zero errors” and “zero emissions” into the pursuit of the strategic goal of "Absolute Zero" the point at which no more adverse risk can be removed from a system which is a benchmark upon which sustained customer satisfaction can be achieved.
