Transport Canada confirmed this morning that the now validated modifications embody extra coaching that offers pilots the choice to disable a “stick shaker” — that’s, “a loud and intrusive warning system when the system has been erroneously activated by a failure within the angle of assault sensor system,” based on a press launch.

Issues with anti-stall system
Transport Canada has been working with different regulators all over the world, however stated it carried out its personal unbiased evaluate of the modifications to the plane to find out if it is secure to fly once more. The U.S. has already cleared the airplane secure to fly once more and Boeing carried out its first flight once more with media on board on Dec. 2.

The committee discovered that Transport Canada had questions concerning the 737 Max as early as 2016, however Canada did not get solutions from Boeing, the producer, or the U.S. Federal Aviation Administration earlier than it accepted the airplane as secure to fly, based on authorities paperwork.
The priority paper, which is a part of the certification course of, is an opportunity for the federal government to lift inquiries to its U.S. counterpart. It is not used to flag issues of safety however as an alternative is a technique to perceive the work the U.S. is doing to certify the airplane to clear it to fly, based on Transport Canada.
The paperwork present Transport Canada’s take a look at pilots requested for extra details about the airplane’s automated anti-stall system, however didn’t get a response earlier than the plane was cleared to fly.
