It's not about paper vs online/computer charts.
It's not about GPS vs sextant + Nautical Almanac.
It is about willingness to learn a skill and discipline.
It is about knowledge. Knowledge is power.
It is critical for a pilot or sea captain to be able to do this.
The FAA knows this, it is sort a right of passage.
Ever been in a situation where your supporting technology has suffered a total electrical failure?
Ever been lost in the desert far away from WiFI/cell service?
Ever read about the 10-20 folks a year that drive down dead end roads or into a river/lake by blindly following their GPS?
It is not about being able to read a chart in the above situations.
It is about being mentally prepared to deal with the unknown, right now, not in five minutes when you can pull over to the side of the road and ponder your situation...
Yes, the right of passage and
tradition perpetuates the knowledge-required for chart use and interpretation. But I don't need that broad a knowledge to safely navigate hundreds of miles across open water, nor presumably to fly VLOS, below 400', etc, etc.
There is no accounting for some of the stupid things people do by
blindly using technology for results, and I am not saying that one should abandon situational awareness in favor of electronics systems. As a matter of fact, IF the GPS system was down, I'd use my chartplotter as a chart for (at minimum) a DR (dead reckoning) plot.
I hear, and have heard for 15 years in the CG Aux, about the possibility of loosing my complete electrical accessory system or other failure to my technology-laden vessel. IF that happened, I would get out my battery powered backup GPS; if that failed, I would use my tertiary battery powered GPS.
Again, I am not saying that one should abandon mental preparedness, and that you shouldn't be prepared to think on your feet, but the use of charts for situations I encounter
at sea, or in the air, is overkill.
