Many thanks to everyone who has (implicitly and politely
) pointed out the flippancy in my point about GPS jamming. I have no way of proving my credentials to you but they do include a 'reasonable amount' of EW and GPS experience, promise.
Let's keep it short. I personally think that whatever means you choose to make landing this thing easier might well be 'jammable' and will never be certified as 100% reliable. So one will have to train for the worst case and as that amount of training will be what the SMEs deem 'just good enough to be safe in all reasonably anticipated conditions' you will probably find that the training burden is pretty much the same.
