Re: Boeing 737MAX Grounded Worldwide Q2 2019

The exact quote of balancing the forces is in the FCOM I think. However, the NNC says to use the main electric trim to control the pitch attitude in step 2. No, it does not. If the pilots could adequately control "airplane pitch" with just the control column, there would be no need to eve...

Re: B737MAX Grounded Worldwide

The 737 MAX will fly when it is safe. With a political delay. Why would you expect a political delay? Seems to me that any advantage that could possibly be gained from this grounding by Boeing's competitors would be far outweighed by the damage caused to airlines from having parts of their fleets g...
