Navigation Databases

How do I load the navigation database into the FMS using SCN 801/901 and later (DTU-100 or SSDTU)?

Instructions for loading navigation database updates into the FMS are contained in the applicable FMS Operator’s Manual Section IV (SCN 60X/70X/80X/90X), or the FMS Reference Guide Section 2 (SCN 803/903/1000/1100). These manuals are available for download through UniNet and should also be maintained in the aircraft accessible to the crew.
