GENERAL
Overview
The Flight Management System (FMS), in
conjunction with other interfacing
equipment on the aircraft, provides
automatic navigation guidance, map
display, and in-flight performance
optimization. The FMS eliminates many
routine tasks and computation normally
performed by the flight crew.
FMS Functions
The major functions of the integrated FMS
are:
•
Storage of navigation data,
aerodynamic and engine data.
•
Means for entry, storage, and in-flight
modification of a complete flight
plan from the departure gate to the
destination runway.
•
Computations of the optimum
vertical profile based on pilot entries
and the performance database.
•
Storage and transmission of data to
generate maps of the route on the
EFIS ND.
•
Calculation of the aircraft’s position
and transmission of this information
for display on the EFIS ND.
•
Automatic selection and tuning of
DME stations for accurate estimation
of aircraft position.
FMS Components
The FMS consists of one Advanced Flight
Management Computer (AFMC), and two
Multipurpose Control and Display Units
(MCDU).
The AFMC receives input from a number of
sources to compute navigation and
performance information:
•
Attitude Heading Reference System
(AHRS) provides heading, attitude
and acceleration data.
•
Inertial Reference System (IRS)
provides position and velocity data.
•
Captain’s digital clock provides GMT
data.
•
Central Air Data Computer (CADC)
provides airspeed, vertical speed
and pressure altitude data.
•
DME provides data for estimating
aircraft position.
•
VHF stations provide data for
estimating aircraft position.
•
Digital Flight Guidance Computer
(DFGC) provides vertical
accelerations and attitudes (pitch
and roll).
AFMC Database
The AFMC database is divided in two major
sections:
•
Performance data:
o
Airplane drag and engine
characteristics.
o
Optimal speed data.
o
Maximum and minimum
speeds.
•
Navigation data:
o
Published airways,
intersections and navaids.
o
Airports, runways, SIDs and
STARs.
The AFMC navigation database is updated
by maintenance every 28 days.
