NAV Canada says thunderstorm, flooding caused flight plan system issue

The organization that provides air navigation services in Canadian airspace says a severe thunderstorm and flooding at its Ottawa facility is to blame for knocking its automated flight plan system offline.

NAV Canada said the system which primarily handles flight plans for flights coming to Canada from Europe was knocked offline shortly after midnight on July 15. Staff were evacuated to a nearby facility where backup systems are located.

In a statement, NVA Canada president Neil R. Wilson says flight plans were processed manually and while there were delays due to problems reinstating connectivity of the system with neighbouring air navigation service providers, safety was not compromised during the outage.

The system was restored around 3:30 p.m. Saturday afternoon.
