Where does the departure flight information for Ronald Reagan Washington National Airport (DCA) come from?
Most flight tracking applications use a single source of data - the US Federal
Aviation Administration's (FAA) Aircraft Situation Display to Industry (ASDI)
data feed. The ASDI data feed tracks flights primarily within the United
States' controlled airspace and contains information for flights controlled
by air traffic control. Pilots file a flight plan with air traffic control
before take off that contains information such as: the expected departure
time, route estimated arrival time Once the flight departs, the FAA publishes
information about the position, altitude and speed of the flight as well
as estimates on arrival times.
For security reasons the information published on the ASDI feed is delayed
for 5 minutes. FlightStats supplements FAA data with data from other sources
including airport and airline data feeds to give you both runway and gate
times whenever possible. Flight information is provided by FlightStats
