The current issue with 737Max had me thinking about how easy it is to overtrim and rely on the ap to correct. Trim is a really important topic, as it stresses the airframe and controls speed and airplane posture.
Effective trimming reduces wear, fuel consumption, eases takeoff and landing, and makes for a more graceful flight. how about putting pink bars on the trim tab so we can see how much physical force we would need to hold the plane level, and to know it is trimmed correctly?
