But when posters come back and promote that GPS is the saviour of navigation.
Has anybody (on here at least) ever actually advocated relying on GPS to the exclusion of all else? I don't remember it, but perhaps somebody could post a link to the relevant thread if there is one.
Personally I use a combination of all the tools that Mr Cessna, Mr Piper or Mr Klapmeier has provided, in all cases backed up with a chart on my lap.
Out of the usual choice of GPS, VOR and ADF as nav aids then GPS (especially with a big screen moving map) seems to me to be by far the easiest tool to use from both the accuracy and workload-reduction points of view. It also maximises the time available for keeping a lookout (if you happen to be in VMC) compared with any other option.
This always seems to turn into a religious debate, but surely in practice most people use at least two navigational aids for non-trivial flights. Perhaps there are some GPS-only fundamentalists out there, but I don't think anybody here is actually advocating that position.
