My idea arose from the concept of fly-by-wire side sticks on the Airbuses. An A380 pilot on YouTube suggested that physically connecting the side sticks could have prevented an accident such as Air France Flight 447. While this theoretically makes sense, Airbus probably has its own reasoning for making the side sticks independent, which I can not currently think of. I was envisioning the same concept applied to the minimums selectors for greater consistency. Then again, perhaps a notification or a change in the color of the minimums text in the case of an inconsistency would be effective.

Maybe Boeing foresaw that the min selector could be use in other situations too, so different selection between left and right mins wouldn't necessarily be a bad thing. For example, the min can be used during takeoff to mark the acceleration/climb trust altitude.

Then again, perhaps a notification or a change in the color of the minimums text in the case of an inconsistency would be effective.

 

I actually deleted a point that touched on this in order to make my post shorter yesterday, but I'll say it here:

Sometimes, all of the features of an aircraft are used not as designed, but as best suits the situation. As an example, some of the aircraft I fly have autopilots, and one of those in particular reminds you of the altitude. Because of this, I use the altitude selector in the autopilot as a reminder for intermediate altitudes on approaches, even though I never even engage the autopilot.

 

While the color change could be helpful, keep in mind that sometimes the discrep would be intentional (then again, if it were intentional, it would be easy for the pilot to look at the different color and just know it's okay).
