UNS-1K FLIGHT MANAGEMENT SYSTEM
- The Universal UNS1 Operator’s Manual or an Operating Manual
accepted by the Certification Authority must be immediately
available to the flight crew whenever navigation is predicated on
the use of FMS. The software status stated in the Operator’s
Manual must match that displayed on the FMS Control Display Unit
(CDU).
- Universal FMS Software version 603.0 (or later approved version)
must be installed.
- FMS instrument approaches must be accomplished in accordance
with approved instrument approach procedures that are retrieved
from the FMS navigation data base. The FMS data base must
incorporate the current update cycle.
- Instrument approaches must be conducted in the approach mode,
and GPS integrity monitoring (when using GPS for approach
guidance) must be available at the Final Approach Fix, as indicated
to the pilot by the INTEG amber annunciator being off and APP
annunciator displayed on PFD.
- Use of FMS guidance for conducting instrument approach
procedures is prohibited with the FMS operating in the dead
reckoning mode (DR annunciation set on PFD).
- The pilot must review the complete transition-approach, comparing
the waypoints and altitudes displayed on the FMS with those on the
published procedure prior to activation to insure that the correct
procedure and transition are selected.
- VNAV is advisory only, and the aircraft altimeter should be the
primary source of altitude information at all times.
- 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.
