It's not required to plan an alternate that has a non-GPS approach if you have a WAAS-enabled GPS receiver, which is almost all of them these days. You can file a primary and alternate with only RNAV approaches.

WAAS won’t help you when the GPS signal is being jammed. It’s ground-based navaids, pilotage, or stay home.

That's a non-sequitur. The person I was replying to said you always have to plan at least one airport with a non-GPS approach.

You’re right of course. I was addressing the larger question of the impact of GPS jamming tests on aviation in general. Less of a reply to you and more of a note to anyone else reading.

But you are still required to check GPS availability and these jamming tests are published way in advance.

I don't remember saying you didn't... Of course you still have to check RAIM availability, but you don't have to plan an alternate with a different approach type.
