the developments of “speed trim” to MCAS and probably many other developments of the 737-100 to the 737 max are being done due to cost.
so who does the maths. Cost of safety?
There is additional lights on each side of the main instrument panel. One for Cabin Altitude and one for Takeoff config. The audio warning is still the same intermittent horn for both.
Just to clarify. Each light is on both sides. 4 lights in total.
