Reliability of Radar Information
The intended use of this Web site is to display the general location and flow of air traffic in the greater San Diego area. WebTrak information is not intended for navigational purposes or airline schedule information. While ANOMS processes a large quantity of radar data with a very high level of accuracy, in a small number of cases, flight plan and noise data may not be correlated correctly. You may also notice aircraft icons sometimes "dropping off" and/or suddenly doing unusual things. This is especially true in the area immediately around SAN, but could also occur away from the airport as well. These "ghost" aircraft are due to radar and aircraft transponder reflections from the ground and high rise buildings around the airport, and possibly from terrain and meteorological conditions farther away from SAN.
