(CNN) Pilots transitioning to the Boeing 737 Max 8 aircraft from older 737 models were given a short, self-administered online course that made no mention of a new system now at the center of two crash investigations, pilots’ unions spokesmen for two American carriers told CNN.
Pilots of Southwest Airlines and American Airlines took courses — lasting between 56 minutes and three hours — that highlighted differences between the Max 8 and older 737s, but did not explain the new maneuvering characteristics augmentation system, know as MCAS, the spokesmen said.
