"The bulletin reinforces existing procedures which all Air Canada crews are now trained on", Fitzpatrick said. A preliminary report is expected at the end of the month.
This measures at what angle an aircraft is flying and air is passing over the wings.
The Lion Air 737 Max 8 jetliner plunged into the Java Sea minutes after takeoff from Jakarta airport on October 29, nosing downward so suddenly that it may have hit speeds of 96 km/h before slamming into the water.
"The aircraft and pilot are grounded for investigation purposes", he said.

"If the nose is trimmed down on an aircraft, it becomes hard for the crew to hold it", a source briefed on Boeing's OMB told the paper. The company did not respond to a request for comment.
The jet's airspeed indicator malfunctioned on its last four flights, and that problem was related to the sensor issue, said Soerjanto Tjahjono, chairman of Indonesia's National Transportation Safety Committee, on Wednesday. The cause of the crash is still unclear.
The Angle of Attack sensor, shown to reporters at a press conference in Jakarta on Wednesday, was manufactured by Minnesota-based Rosemount Aerospace Inc.
Data from the black box of the Lion Air 737 Max that fell into the sea with 189 people onboard has confirmed there was an issue with the plane's airspeed indicator. "If there are urgent findings to be delivered, we will convey them to the operators and to the manufacturer", he said, according to AP.

"We are still focusing on handling the families of the victims, including returning their remains to their home", Sirait said by phone. "Is this fatal? NTSC (National Transportation Safety Committee) wants to explore this", he said.
This warning extends to both Air Canada and WestJet pilots, since both the airlines use 737-Max planes regularly. The audio device may be crucial to unraveling what happened during the flight's final moments.
Pilots can counteract this for up to 10 seconds at a time by pushing a switch on the airplane's controls. In addition, a system known as elevator trim can be changed to prompt nose-up or nose-down movement. In the early days of the jet age, the elevator trim system was linked to several accidents.
He said the pilot had landed the plane safely on that occasion.
"Lion Air has failed", said a man who identified himself as the father of passenger Shandy Johan Ramadhan, a prosecutor in a district on the island where the flight was headed.
