The links are for official documents published by the UK CAA, they are the ones in charge, the documents are there for a reason, and not to be used as toilet paper, although you may choose to use them for this purpose, democracy rules in the UK after all.
The CAA may, in the future , change itīs view on the use of GPS for VFR flights, untill they do, they expect GPS not to be used as primary mean of navigation when flying VFR, if you do, you are not following the rules, thus flying ilegally, wether it makes sense to you or to me, it is a different matter, we are talking about what is legal or not.
Of course GPS gizzmos are nice and reliable nowadays, and a very useful tools too, same for VORīs & DMEīs, but they are not accepted by the CAA as primary means for VFR navigation.
If that sounds an absurd, Beagle, you may want to refresh your knowledge on very basic regulations, which any FI should be familiar with.
