So then, someone explain to me why we need ADS-B? We have radar, we don't receive ADS-B where there is no ADS-B, we have Xponders with ALT encoders. It's been working just fine this way for 50 years.. So now, the feds need to know everything about our flights... Ya, nothing here to see.

Take a trip to Alaska, or anywhere else with limited radar coverage, especially low altitude. You will then answer your own question. Suddenly, radar coverage isnít necessary as long as you have ground ADS-B coverage.

Iím very pro-ADS-B for a variety of reasons. Youíre against it, clearly. Different folks, different strokes...

When you get your first letter or fine from the feds.. You let me know. Every right you give up is a right you'll never have again. Think about that. AND I think that anyone that wants ADS-B should have it, but it should not be forced on everyone.

The answer to your question is: money. The FAA wants to save money, by passing on ATC costs to pilots. ADSB-in is just a bone thrown to pilots, to try to make it easier to swallow. The FAAís long term plan is to require adsb everywhere, and then shut down very expensive radar. Long term, ground controllers at the largest airports will be fired, and ground control automated via adsb (Why do you think you have to broadcast your wingspan, and where your nose is wrt the gps antenna? Automated ground control.) Itís all about money.

BTW, if you have adsb-out, there is no option to turn it off. You are required by the current FARs to run it, whether in rule airspace or not.

Default adsb

the FAA is also testing space based adsb. They need it to track across vast spaces like the oceans. VOR's are also going to be leaving for GPS. Its about making things safer. It has been a great help for Houston center for helo traffic on the rigs. Our ground based radar systems are expensive and aging. FYI for ARTCC radar it is mosaic from 5 radar sites and ADSB.

Bad guys = radar.

ADSB needs a backup.

Radar is going nowhere.

I believe the plan is to leave in place radar which is co-shared with DOD, e.g., along the border. Donít be surprised, though, if the FAA tries to get DOD to pick up the entire cost.
ADSB has a backup. Youíre required to keep your transponder, and all the airlines have TCAS - they ping transponders for collision avoidance. For the rest of us, non-airline types ó well, the faa really doesnít care.

Yes. But those long range search radars are owned and completely funded by the DOD, not the FAA. The FAA just has access and uses that DOD radar data. The DOD is not interested in data from the FAA owned and funded approach radars. They serve no long distance air defense purposes and military fighter aircraft carry their own radars for short distance air defense purposes.

Never heard that. Can you cite the section that requires this?
