3) APR ACTV mode m ust be ann unciated at the Final
Approach Fix.
4) Accomplishment of I LS , LOC, LOC-BC, LOA, SDF, and
M LS approaches are not authorized.
5) When an alternate airport is required by the applicable
operating rules, it must be served by an approach based
on other than G PS or Loran-C navigation .
6) The KLN 89B can only be used for approach guidance if
the reference coordi nate datum system for the i nstrument
approach is WGS-84 or NAD-83. (Al l approaches in the
KLN 89B database use the WGS-84 or the NAD-83
geodetic datum).
e. For BRNAV operations in the European region :
1 ) With 23 (24 if the altitude input to the KLN 89B is not
available) or more satel lites projected to be operational for
the flight, the aircraft can depart without further action.
2) With 22 (23 if the altitude input to the KLN 898 is not
available) or fewer satellites projected to be operational for
the flight, the availability of the G PS i ntegrity (RAIM) should
be confirmed for the i ntended flight (route and time). This
should be obtai ned from a prediction program run outside
of the aircraft. The prediction program m ust comply with
the criteria of Append ix 1 of AC90-96. In the event of a
predicted contin uous loss of RAIM of more than 5 minutes
for any part of the i ntended flight, the flight should be
delayed, cancelled, or rerouted on a track where RAI M
requirements can b e met.
AlliedSignal 's Preflight, Version 2.0 or later computer based
prediction program may be used for the RAIM prediction .
Alternate methods should be submitted for approval i n
accordance with Advisory Circular AC90-96.
