FAA Mission and Vision
Safety  The foundation of everything we do
Mission
Our continuing mission is to provide the safest, most
efficient aerospace system in the world.
Vision
We strive to reach the next level of safety, efficiency,
environmental responsibility and global leadership.
We are accountable to the American public and our
stakeholders.

Required Navigation Performance
(RNP) Approaches
Consistent, controlled
approaches
Substantially shortened flight
path length (green vs. blue)
Noise exposure reductions
with accurate routings over
less noise sensitive areas
(e.g. Elliott Bay)
Reduced greenhouse
emissions
Minimized operational costs

Federal Aviation
Administration

Greener Skies - An Example of RNP -
- Goals and Objectives -
Reduce track miles to minimum possible
Reduce noise exposure and emissions to
Seattle / Puget Sound region
No level-offs - Idle thrust from cruise altitude to
final approach
Absorb delays at cruise altitude
Reduce/eliminate low altitude radar vectoring
Reduce fuel burn

Delivering NextGen 
Automatic Dependent Surveillance - Broadcast
ADS-B
Uses GPS technology to determine an
aircraft's location and airspeed, and
broadcasts that information to controllers
and other equipped aircraft via a
nationwide network of ground stations.
ADS-B provides surveillance where radar
can not be deployed, such as remote
areas of Alaska and the Gulf of Mexico.
ADS-B also enables aircraft-to-aircraft
surveillance.
Benefits                          Moving Forward
Baseline radio stations are in place
Provides more frequent position update-
nationwide
rates than radar = precise location
Surveillance coverage available 
information of aircraft
En Route in 2015 - Complete
Provides in-cockpit traffic and weather
Terminal and Surface by 2019
information
Reduced separation
Improves safety for pilots
Oceanic in-trail altitude changes
