The computer system that alerts airlines and pilots flying in Canadian airspace to potential hazards suffered a brief crash on Wednesday.
The system, called Notice to Air Missions (NOTAM), is managed by Nav Canada, a private not-for-profit organization that owns and operates Canada’s air traffic control system.
Nav Canada said it began experiencing problems with its NOTAM input system Wednesday morning, leaving it unable to send new updates to airlines.
No flights were delayed as a result, Nav Canada said, and the system was back online in the early afternoon.
“We continue to monitor our systems and investigate the cause,” the company tweeted.
Prolonged outage in the US
A number of Canadian flights to and from the US were disrupted on Tuesday and Wednesday due to a failure in the US NOTAM system.
A computer outage that began Tuesday night has caused thousands of delays and hundreds of canceled flights, quickly cascading through the U.S. airport system
The US Federal Aviation Administration said the cause of the outage was still unclear. Nav Canada said it does not believe its own outage is related to the one south of the border.
