Air Canada briefly grounded its planes Thursday due to a problem with its computer system.
A “technical issue” with the system the airline uses to communicate with aircraft and monitor their performance prompted a halt to operations, the Montreal-based company said.
“There have been some delays as a result, but the system is now returning to normal, and the precautionary ground stop has been lifted,” said spokesman Peter Fitzpatrick in a statement Thursday afternoon.
“The effects were limited.”
More than 200 Air Canada flights, or about 40 per cent, were delayed, according to tracking service FlightAware. That compares with about 35 per cent on Wednesday.
Air Canada said it advised Nav Canada and the U.S. Federal Aviation Administration of the temporary freeze, which lasted about an hour.
