TIS-B / ADS-B will be MUCH better, but we have to protect TIS until
those systems are fully operational with equivalent coverage.

Isn't the source of the traffic information the same for both TIS (mode-S) and
TIS-B (the traffic part of ADS-B)?

What is it that's being decommissioned? Is it the mode-S (which TIS-B doesn't
use) transmitters? ...or is the data being cut off at the source?

Thanks. Dave
