Figure 1 ADS-B Depiction
When properly equipped with ADS-B,
both pilots and controllers will, for the first time,
see the same real-time displays of air traffic. Pilots
will have much better situational awareness because
they will know where their aircraft is with greater
accuracy, and their displays will show them all the
aircraft in the airspace around them. Pilots will
be able to maintain safe separation from other aircraft
with fewer instructions from ground-based controllers.
At night and in poor visual conditions, pilots will
also be able to see where they are in relation to
the ground using on-board avionics and terrain maps.
ADS-B has been shown to decrease the number of mid-air
collisions, and because all aircraft must be equipped
per the FAA mandate, all aircraft flying will have
this capability.
ADS-B will also increase airspace capacity. By utilizing
more accurate tracking, aircraft will be able to fly
safely with less distance between them. And, because
ADS-B accuracy also means greater predictability,
air traffic controllers will be better able to manage
the air traffic arriving and departing from congested
airports, resulting in even more gains in capacity.
This in turn equates to better routing which leads
to decreases in aircraft operation costs.
