Figure 16-85. Database Units
To use the USB port (DBU-5000), the FMS
data and IFIS data must first be loaded onto a
computer and then moved to a USB drive. The
USB device must not have preinstalled soft-
ware which manages passwords or security, as
this can interfere with the proper loading of
the database. If Jeppesen charts are involved,
it is recommended to have a device at least
1GB in size. This drive is then plugged into the
USB port in the aircraft. The generated
prompts are displayed on the CDU. In this
case the laptop does not need to be connected
to the aircraft.
FMS INITIALIZATION
The FMS must be initialized prior to each
flight. The initialization may be accomplished
using the following acronym:
V – V erify FMS database coverage and
effective dates
I – I
nitialize FMS position
P – P lan the flight (build the flight plan)
P – P
erformance initialization
For further explanation of these steps, refer to
the FMS quick reference guides and FMS
manuals.
VERIFY
Verify the coverage of the database and verify
the currency of the database. Flight with an
out of date database is allowed, but the use of
FMS / GPS dependent procedures are not au-
thorized.
INITIALIZE
Initialize the FMS position, or verify that the
current position is correct. This position needs
to be in a latitude / longitude format and can
be retrieved / verified using airport reference
point (ARP), a pilot defined point or the
GPS.The GPS should be able to update the
system quickly unless the aircraft was moved a
significant distance (>40nm) with the FMS in-
operative or the FMS was removed and re-
placed. This step will consist primarily of
verifying the known position as opposed to ac-
tively entering the position.
PLAN
The flight plan will be loaded on the FPLN
page. ORIGIN, DESTination, and fixes along
the route of flight may be entered. Instrument
Departures or Arrivals may be loaded as nec-
essary. Loading a origin and destination,
ONLY gives you a straight line distance and
allows the system to retrieve departures, ar-
rivals, and approaches for those two airports.
It is has not loaded a “flight plan.”
PERFORMANCE INITIALIZATION
Performance is initialized by entering the de-
sired weights for passengers, cargo, fuel, etc.
The CRZ ALT is an optional entry and helps
the unit forecast a descent point later in the
flight. CRZ ALT does not change any fuel cal-
culations when changed or updated.
VERTICAL NAVIGATION
The FMS-3000 is capable of creating and dis-
playing a descent profile or a glidepath to com-
ply with crossing altitude restrictions issued by
ATC, or an associated instrument procedure.
The Flight Guidance System is able to use this
information to capture and track the com-
puted glidepath.
VNAV altitude restrictions are displayed in
magenta along the right side of the LEGS
page (Figure 16-86). A VNAV altitude will be
automatically entered if it is part of a database
derived procedure. The pilot can manually in-
sert an altitude associated with any waypoint.
