Kalavo,
I have RNP transitions to CAT 3 Autoland with GBAS....
You tout the WAAS procedures numbers, like you are with the FAA, but in reality, there are NO or very, very few, WAAS procedure plates. The only ones I know of are helo ops in the Gulf.
I would love to hear from anyone who has a commercial AC is certified to use WAAS, has used WAAS IFR, or even, where in the hell they used it in the US!
Obviously, you have NO idea what it takes to certify an AC for WAAS. It is a different antennae system, different MMR, and different requirement for crew training.
I will certainly agree with you WAAS, SBAS, LAAS, etc, are a waste of money...
Do you understand that WAAS is an augmentation system, that it just broadcasts a correction factor through a sat? GBAS does exactly the same thing, just through a ground based receiver, at the airport you are flying to?
Why spent the $2 billion floating a sat for WAAS, when you can spend $2 million for a GBAS, and have better accuracy?
I also suppose you also werent aware that ASA is a 50% owner of the GBAS system....
