using current flight publications.
8.4.2. En route NOTAMs.
8.4.3. En route weather.
8.4.4. FLIP products. The appropriate FLIP products to ensure compliance with any
special procedures that may apply.
8.4.5. Diversion fields. Emergency diversion fields and approaches.
8.4.6. Compliance. Comply with the jet route or airway system as published on the FLIP
en route charts and air traffic clearances. You must also ensure your aircraft is equipped
and authorized to operate in the airspace along your route of flight. For example, only
aircraft certified through their MAJCOM for RNP-5 may operate in the European Basic
RNAV (BRNAV) structure. Consult your MAJCOM and Mission Design Series (MDS)-
specific guidance if you have any doubts concerning your aircraft’s capabilities.
8.4.7. Enroute Navigation in High Latitudes. Enroute navigation in higher latitude
regions may be based on reference to true or grid north instead of the customary
reference to magnetic north. Procedures vary greatly between aircraft type and avionics
capabilities. Thorough mission planning, including review of applicable aircraft/avionics
specific procedures and limitations, is essential to accurate navigation at higher latitudes.
8.4.7.1. When flying at higher latitudes, review the enroute charts carefully to ensure
you are cognizant of the heading source required by the instrument procedures in the
airspace you are transiting, and the orientation reference of the NAVAID. This is
annotated on the enroute chart as shown in Figure 8.3.
