As FAA is well aware, important sectors of the NAS often approach
– and sometimes exceed – current capacity limits, especially when
weather affects the system, which causes flight delays,
inefficient routings and increased fuel consumption, in order to
maintain the highest level of system safety. ADS-B deployment and
NextGen offer significant improvements over the existing outdated,
radar-based ATC system. These additional reasons drive ATA’s
interest in this rulemaking proceeding.

See what I mean?


Yet the FAA NPRM does not guarantee that implementation of ADS-B Out
will result in system capacity improvements...particularly en route
separation standards.

Here are words from the NPRM:

"At this time the FAA cannot determine the extent to which separation
standards might be reduced."

"The FAA may examine the possible reduction of separation standards
once ADS-B has been certified to meet existing separation standards
safely and consistently.

Right. It sort of makes one wonder about the competence of the ATAA.
