Now, if we had more rational criteria by authorities, .....
I'm sure CASA will lead the way in THE rational use of the current GPS constellation - NOT!
As for the future with Galileo - the term "pie in the sky" comes to mind.
It is CASA and our Government with their head in the sand for proposing GBAS, and for missing out on SBAS, especially with much of the hardware for SBAS already paid for by Japan.
CASA appears to be trying to repeat the DME(A) going it alone with an orphan system with GBAS. GBAS has no future, except in Australia, where we waste money on stupidity, and a re parsimonious when it comes to common sense.
