Pilot's Manual
FUEL — Before takeoff, the fuel quantity signal conditioner provides
the FMS with fuel quantity on-board. The pilot must accept or change
the transmitted fuel quantity on the CDU fuel page. After engine start,
the FMS receives real time fuel flow information independent of the air-
craft indicating system. Specific range and endurance are provided
along with fuel, time and distance predictions for the destination.
PERF (performance) — A performance program in the FMS can com-
pute takeoff speeds, takeoff N takeoff distance and landing speed.
1 ,
The operator enters pertinent data such as takeoff configuration and
environmental conditions mostly through menu selections. V Speeds
and balanced field data is calculated and displayed. For landing, Vref
is calculated along with approach speeds for different flap settings.
NAV (navigation) — All pertinent en route navigation data is dis-
played on the first NAV page of the CDU. This page along with the
PFD/MFD displays provide complete integrated real time information
on flight progress.
DTO (direct to) — A dedicated function key can be used to navigate
from present position directly to any point on or off the present flight
plan.
VNAV (vertical navigation) — Vertical navigation pages allow the op-
erator to define waypoints with altitudes or flight levels. Features such
as computed top-of-descent, target vertical speed and vertical direct-to
are included. The FMS outputs vertical commands to the flight director
when selected.
HOLDING PATTERNS — Holding patterns may be programmed at
any waypoint on or off the flight plan or stored in the navigation data
base as part of a SID, STAR or approach procedure. The holding pattern
page provides a graphic depiction of the holding pattern. The pattern
is defined with some crew inputs, and when the ACTIVATE line select
key is pressed, the aircraft will proceed from its present position direct-
ly to the fix and make the appropriate entry (direct, parallel or tear-
drop), all automatically calculated and flown by the FMS.
