Important Notice
iii
The Global Positioning System (GPS) is operated by the United States Department of Defense which is solely
responsible for the accuracy, daily operation, and maintenance of the satellite constellation. System accuracy is
affected by the Department of Defense’s Selective Availability (SA) and the Dilution of Precision (DOP) attributed to
poor satellite geometry.
Due to implementation of Selective Availability by the United States Department of Defense (DoD), all GPS receivers
may suffer degradation of position accuracy. The DoD has stated that 95% of the time horizontal accuracy will not be
degraded more than 100 m and 99.9% of the time accuracy will not be degraded more than 300 m.
Installations of TSO C-129a authorized Apollo GX50/60’s and TSO-C-129 authorized GX55’s may be approved for
supplemental navigation only. The Apollo GX50, GX55, or GX60 may be used as the primary navigation data
display, however, other means of navigation appropriate to the intended route of flight must be installed and
operational. It is not required that these other systems be monitored.
