USA - Airline pilots on at least two US-flown Boeing 737 Max 8 planes had reported that the automated system caused the aircraft's nose to tilt down sharply and suddenly after take-off. The pilots said they were able to recover quickly following the aggressive dive - descending as fast as 1,500 feet per minute - by disconnecting the autopilot. However, the tilting problem did not appear related to the new automatic anti-stall system that's suspected of contributing to the deadly Indonesia crash on that aircraft model in October. The pilot reports were filed last year in a database compiled by NASA. They are voluntary safety reports and do not publicly reveal the names of pilots, the airlines or the location of the incidents. The Boeing Max 8 jet is now at the center of a growing global ban after more than 40 countries grounded the model following the second fatal crash in five months.
