The MEL will not advise you always on the interconnectivity of different items will it ?
Perhaps not on Airboos aircraft, and indeed on some Boeing types, however if one was to glance at a Lockheed TriStar MEL, one finds
all the relevant information.
Having said this, the TriStar positively has more systems redundancy than most any other type, so perhaps is a bad example...
When you combine poor pilot systems training together with inadequate information from the manufacturer, the Commander is between a rock and a hard place, and certainly is ill-prepared to make a reasonable decision. This is very unfortunate.
It all comes down to cost, doesn't it?
It costs money to have detailed systems knowledge taught, so this item is overlooked for expediency.
