The FAA announced that it will be conducting testing on the GPS network over the next several days that will affect large areas of the southeastern United States.
During testing, the GPS signal may be unreliable or unavailable within a 335NM radius centered at 300500N/0800500W or the OMN VOR 055 degree radial at 71 NM at FL400 and above, decreasing in area with decrease in altitude to 285NMR at FL250, 220NMR at 10,000 FT MSL, 182NMR at 4,000 FT AGL and 139NMR at 50 FT AGL. Pilots are strongly encouraged to report anomalies during testing to the appropriate ARTCC to assist in the determination of the extent of GPS degradation during tests.
