OUR INTERMITTENT GPS FUTURE

摘要

Discussions about the veracity of GPS as a sole-source navigation mechanism for the future have intensified. I've written about this before and my views haven't changed, but let me express them a bit more stridently. Until and unless various official agencies, led by the military, find some alternative to widespread GPS interference, GPS as the primary means of general-aviation navigation is a singularly bad idea. No, I'm not one who laments the loss of VHF-nav skills. My objection lies solely with GPS practicality.
