If you read through the available information on emergencies, there is but one conclusion. Everything is covered, several times, in the millions of words written about this but much, even most, of it revolves around the legalities. Logic suggests that if you are up to your ears in gators, what counts are results and if you get a good result you can think about the legal part later.
Are there fewer thunderstorm-related private airplane crashes now than there were before Nexrad was beamed into almost every cockpit? The answer is yes, no and maybe. The reason for the vacillation is the simple fact that we have little or no information on exposure.
I am convinced that screens full of information are not a key to operating an airplane safely. The most important picture of all is not on a screen, it has to be in the pilot’s mind. A mental picture of where you are, where you are going, and how you are going to get there simply can’t be replaced by a picture on a screen. Nor will a screen show the churning inside a cumulonimbus.
