Boeing will now make the disagree light standard in all new 737 Max planes, and will provide the indicator free of charge for customers who want it.
“All primary flight information required to safely and efficiently operate the 737 Max is included on the baseline primary flight display,” Boeing said. “All 737 Max airplanes display this data in a way that is consistent with pilot training and the fundamental instrument scan pattern that pilots are trained to use.”
If everything required was already fitted, why the change to include extra instruments ?
And likewise, if all for safety and efficiency was already included, the stockholders of the US airlines who spent not inconsequential sums on buyig these extra options will presumably ask their board why money was "squandered" on extra frippery.
Someone at Seattle really needs to tell the seemingly totally disconnected
PR-corporate media managers in Chicago a home truth or two.
