- When using FMS guidance for conducting instrument approach
procedures that do not include a GPS reference in the title of the
published procedure, the flight crew must verify that the procedure
specified navaid and associated avionics are operational.
- For airplanes equipped with single FMS, when using FMS guidance
for conducting instrument approach procedures, the procedure
navaid must be tuned and valid, and the raw data must be
displayed in the cockpit, under the following conditions:
- For VOR approaches (where the procedure specified navaid is
a VOR only navaid - no DME capability) and NDB approaches,
without GPS (GPS failed or RAIM out of limits or unavailable).
- For any instrument approach (other than a GPS stand alone
approach), outside the Brazilian Airspace, with GPS as the
navigation sensor.
- ILS, LOC, LOC-BC, LDA, SDF and MLS approaches, using the
FMS for guidance, are prohibited.
- When flying to an airport where GPS (non-overlay) is the intended
approach, prior to dispatch, the crew is required to verify that the
predictive RAIM at the destination ETA is within the approach
criteria. This information (RAIM AVAILABLE), is displayed on the
PREDICTIVE RAIM page, accessed via the GPS STATUS page.
- When the approach at the destination is based on GPS and an
alternate airport is required by the applicable operating rules, the
alternate must be served by an approach based on a navigation aid
other than GPS. The navigation aid must be operational and the
airplane must have operational equipment capable of using that
navigation aid.
- IFR non-precision approach approval is limited to published
approaches in the WGS-84 coordinate datum within US airspace.
Approaches to airports in other airspace are not approved unless
authorized by the appropriate governing authority.
