D. During testing, the GPS signal may be unreliable or unavailable
within a 320NMR centered
at 323652N/1061722W or the BWS VOR 230.5 degree radial at 19 NM at
FL400 and
above, decreasing in area with decrease in altitude to 265NMR at
FL250, 185NMR at
10,000 FT MSL, 190NMR at 4,000 FT AGL and 155NMR at 50 FT AGL.
E. 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.
The NOTAMs discussed in this advisory may change with little or no
notice. Pilots are
advised to check NOTAMs frequently for possible changes prior to
operations in the
area. NOTAMs will be published at least 24 hours in advance of any GPS
tests.
