Approach Procedures
Operations
You should always plan the route and approach to any required
alternate airport such that a supplementary navigation system, such as
GPS or Loran-C may not be available. The traditional en route and
approach Navaids must be operating and the aircraft must have the
required avionics to use for required alternates. You may use a
supplementary system, such as GPS to navigate to an alternate airport.
You may execute a GPS approach to a required alternate, but you must
plan for the possibility that GPS navigation will not be available.
FAA guidelines on IFR use of GPS and GPS approaches are contained
in an FAA Advisory Circular (AC), AC 90-94. You should be familiar
with the information in this AC before attempting GPS approaches.
In order to use the Apollo NMS for an approach, the approach must be
selected from the NMS database and loaded into the active flight plan.
Only approaches found in the Apollo NMS database may be flown
with the Apollo NMS.
