Hundreds of regional flights were canceled due to the navigation system failure

Washington, D.C. - Yesterday, some regional airlines in the United States had to cancel their flights due to error messages from the navigation systems of the planes.

Around 400 scheduled regional flights were canceled due to the problem.

Mesa Airlines, which operates on behalf of American Airlines and United Airlines, Delta subsidiary Endeavor Air, United contractor GoJet, American's subsidiary PSA Airlines and SkyWest are among the airlines affected by the issue.

Delta Air Lines said the company canceled 80 flights by its regional subsidiary Endeavor Air.

The problem was with the navigations systems of the some Bombardier CRJ series jets, which were made by Rockwell Collins.

The issue is currently being investigated by the U.S. Federal Aviation Administration. The Agency thinks that the problem may have resulted from a software update to the aircraft's navigation systems.

Nor Bombardier neither Rockwell Collins commented on the issue.

If we eliminate the software update from the manufacturer, the scariest scenario could be a complete system hack by an external source.
