Unbelievable Facts

An example of relying on gadgets.
During the Gulf War some sailors were having navigation issues as the US Defense Force was tweaking the GPS readings and at times totally shutting down the systems to disrupt the Enemy.
During a conversation with a fello Yachty around that time apparently some of the crew on a vessel were telling the Skipper that he was off course.
Skipper said he`d been using a sextant for a long time & that he knew what he was doing and where he was.
Turned out the old captain was correct and spot on course.
Gadgets are only good when they are working.

I'm trying to get my pilots license. To go anywhere beyond Cue I will have to get my cross-country endorsement that includes navigation without the fancy EFB's (electronic flight bags}. We used to navigate by map long before GPS came about so I don't think it'll be too difficult but we have to be proficient in an obsolete form of navigation. I guess maps don't suffer too badly from flat batteries or power surges unless it's a direct lightning strike in which case navigation might be the least of your problems. Of course there are areas such as Mount Magnet just 80km down the road, an area where the compass cannot be relied upon.
