Dom:
I do not have a crystal ball and I would not presume to say that I know the ultimate outcome. I can only say what I believe. I believe strongly that if Galileo goes up and the safety of life services we envision are made mandatory for airplanes in the EU, that amateur radio operators in Europe in particular will lose all of L band. I believe this because the manufacturers will not want to have to provide highly selective front ends that will reduce the near/far problem to manageable levels. There are simple laws of physics that dictate the nature, size, etc. to get these filters to operate with the required Q that will allow us to continue to aim thousand of watts into high gain antennas and point them up. Possibly the aviation control bodies such as our FAA will force them to include them. But the manufacturers will not do it willingly when only a few hams are in the way of a multi-billion dollar industry.
Again, for the record, these are my opinions based on an understanding of what it will take to make them immune to interference from us.

Hi Bob, N4HY
You said"
What will happen if the Galileo goes up is that no European airport will allow a commercial jetliner to land without the Galileo system. This will inevitably lead to this basic system being in world wide use for navigational purposes.
Does this imply that all 23 cm EME stations have to be moved away from 1296 MHz ?
