Air traffic control systems are almost completely safe from the millennium bug, the group that runs communications networks for the world?s airlines and airport authorities said last week.
However, the group refused to completely rule out the risk of failures, and admitted there almost certainly will be problems in some parts of the world.
John Watson, director general of SITA - which operates a voice and data services network for 650 airlines, airport authorities and aerospace manufacturers in over 180 countries worldwide - told Reuters last week that its network was ?99 per cent compliant".
Watson said SITA is in the final stages of testing and contingency planning for the network, which transmits more than 100 trillion bits of information each month. SITA has spent more than $30 million on its compliance programme.
Contingency planning was necessary, Watson conceded, because of the risk of failure in ?more remote parts of the world".
